Projects

The Planetary Aeronomy Division of IASB-BIRA is involved in the different national and international projects:

 

ExoMars Trace Gas Orbiter 2016 and the NOMAD instrument

Started in 2010 - to be launched in 2016

ExoMars is the name for 2 missions to Mars and IASB-BIRA began their contribution in 2010. NOMAD is a 3-channel spectrometer developed by an international team that was selected from many proposals for the Trace Gas Orbiter that will launch in January 2016. The aim of NOMAD is to better characterize the atmosphere of Mars - measuring vertical profiles of various species at different longitudes, latitudes and seasons; mapping possible sources and sinks of rarer gaseous species - for example methane; examining aerosols and their fluctuations over a Martian year.

In Belgium, there are teams at IASB-BIRA, ROB, CSL and Université de Liège involved in the scientific preparation for exploitation of this mission. Engineers are involved at IASB-BIRA, CSL, OIP, Lambda-X and Thales Alenia. The expertise required ranges from mechanical engineer and CAD designer to hardware and software electrical engineers and calibration technicians. The design is already well advanced and NOMAD will pass from Phase C to Phase D via Critical Design Review (ESA chaired) in September.

The data exploitation pipeline will also be prepared at IASB-BIRA, and operations will be planned from here.

UPWARDS

March 2015 - February 2018

The goals of the UPWARDS project match the topics, challenges and scope of the Compet-8-2014 call (Horizon 2020). The UPWARDS Consortium undertake five grand science themes which challenge our current understanding of the complex couplings of the Mars’ climate:

  • exchange of trace species between subsurface & atmosphere;
  • global cycle of Martian water;
  • surface properties and behaviour of suspended aerosols and dust storms;
  • drastic changes at the day/night terminator;
  • coupling of the lower and upper atmosphere and escape to space.
All topics are addressed by experts in the field, exchanging results and knowledge in a truly synergistic and interdisciplinary collaboration.

The Planetary Aeronomy group of IASB-BIRA is a partner of the project.

SCOOP, a BRAIN-be network project

December 2014 - March 2019

The goals of the SCOOP (Towards a SynergistiC study Of the atmOsphere of terrestrial Planets) project match the topics, challenges and scope of the BRAIN-be call 2014 of the Belgian Science Policy (BELSPO). SCOOP has as its overarching objective the revision and exploitation of data from the European Mars Express (MEX) and the European Venus Express (VEX) missions as well as other Martian missions such as NASA’s Mars Atmosphere and Volatile Evolution (MAVEN).

It will use a synergistic approach by combining different fields of research in aeronomy and integrating the different layers of the Mars and Venus atmospheres from the surface to the upper atmosphere. It will address major open science questions regarding the atmospheric system by seeking to comprehend the interactions between its various elements. SCOOP will also 1) prepare for ESA’s ExoMars 2016 Trace Gas Orbiter (TGO) data analysis and exploitation by developing tools to be tested on selected data from current missions and on the first returned data of TGO; and 2) deliver enhanced scientific context and datasets for defining and designing future missions to our neighbour terrestrial planets.

The Planetary Aeronomy group of IASB-BIRA is coordinating the project. The LPAP of the Université de Liège and ORB are also partners of SCOOP.

EuroVenus: a FP7 European project

2014 - 2016

EuroVenus stands for European Unified Research on Observations of Venus using coordinated Space- and Earth-based Facilities. It is a project funded by the EU within the Seventh Framework Programme for Research and Technological Development, EU's main instrument for funding research in Europe.

Venus is Earth's closest sibling, but it has ended up with a radically different climate. Venus atmospheric science is thus increasingly important in an era in which we are trying to understand the divergent evolutionary outcomes for terrestrial planets, whether we are considering the future of our Earth or the habitability in other solar systems.

The goal of this proposal is to investigate in detail the dynamics and composition of the middle and lower atmosphere of Venus by combining data from Venus Express instruments (VIRTIS, VMC, SOIR) with simultaneous data acquired from several ground-based telescope facilities during the course of ESA's Venus Express mission.

We will perform coordinated observations to provide a detailed analysis of dynamical and chemical couplings between different levels of the atmosphere that are probed simultaneously by different instruments.

The IASB-BIRA contribution to EuroVenus occurs through the SOIR channel of the SPICAV instrument on-board Venus Express. The temperature structure of the upper atmosphere and the light absorption due to aerosols in the mesosphere derived from SOIR data at terminator will help resolving the latitudinal dependency of the aureole observed with a set of coronagraphs during the Venus transit in June 2012.

In addition, this project gives access to a platform of complementary ground-based observations and of data from other Venus Express instruments for cross-validating SOIR vertical profiles of temperature, aerosols and minor constituents.

InterUniversity Attraction Pole (IUAP) Planet TOPERS

2012 - 2017

PLANET TOPERS stands for Planets, Tracing the Transfer, Origin, Preservation, and Evolution of their ReservoirS.

The group is an Inter-university attraction pole (IAP) financed by the Belgian Science Policy (BELSPO) and addressing the question of habitability in our Solar System.

Based on the only known example of Earth, the concept of habitability refers to whether environmental conditions are available that could eventually support life, even if life does not currently exist.

Terrestrial life requires liquid water. The stability of liquid water at the surface of a planet defines a habitable zone around a star. In the Solar System, it stretches between Venus and Mars, but excludes these two planets. If the greenhouse effect is taken into account, the habitable zone may have included Mars in the past while the case of Venus is still debated. Important geodynamic processes affect the habitability conditions of a planet. The group works in an interdisciplinary approach to understand habitability. The dynamic processes, e.g. internal dynamo, magnetic field, atmosphere, plate tectonics, mantle convection, volcanism, thermo-tectonic evolution, meteorite impacts, and erosion, all impact on the planetary surface, the presence or not of liquid water, the thermal state, the energy budget and the availability of nutrients.

The Space Physics Division and the Planetary Aeronomy group of IASB-BIRA are involved in the part of the project that deals with the thermal-chemical evolution of planetary atmospheres (net loss, sources and chemical reactions) and its interaction with surface, hydrosphere, cryosphere, and space to determine the evolution of pressure, temperature and composition in time, and the existence or not of liquid water. This includes the greenhouse effect and the regulating role of a magnetosphere on atmospheric losses. The comets and asteroids volatile mass influx from space into the atmosphere are dealt with as well.

 

BeMind : collaboration with ISRO (India)

2012 - 2015

In 2012, IASB-BIRA was selected for a small amount of funding to start cooperation with India. The Indian Space Research Organisation (ISRO) is planning to send an instrument that resembles NOMAD to Mars in 2014 and was looking for collaborators with experience in radiative transfer models for Mars. A first meeting took place after the International COSPAR conference in July 2012 in Mysore.

Further to this positive interaction, more funding was requested to allow more interactive interchange. The BeMind proposal was approved and will allow more face to face meetings in India and Belgium. We hope to have students from India participate in NOMAD calibration experiments and to be able to test NOMAD pipeline on PRISM data after launch!

8-10 May 2013 - A BeMInd meeting took place in Bangalore in May 2013. This was the First ISPA workshop (Infrared Spectroscopy of Planetary Atmospheres) jointly organized by ISRO and BISA. IASB-BIRA researchers presented the Planetary Aeronomy activities of the Institute while their Indian colleagues presented their space activities. Two 'hands-on' workshops were held on how to use the SOIR/VEX data and the ASIMUT-ALVL software.

May 2014 - The next meeting organized within the BeMInd project will take place at the Kodaikanal solar observatory in India. The 2d ISPA workshop will be again organized jointly between IASB-BIRA and Indian scientists from ISRO (Indian Space Research Organisation) and IIA (Indian Institute for Astronomy).

June 2014 - Finally, the 2014 meeting was organized once more at Bangolare at the ISITE site of ISRO. The agenda comprised 3 full days of presentations, mainly from Indian researchers on Venus and the possibility to build a next Venus mission ! The last 2 days of the week were reserved for 'Hands on': one day on ASIMUT and How to use the SOIR data; the second day: same for VMC and VIRTIS data, plus a very interesting First Course on radar telemetry.

 

HiResMIR

2012 - 2015

HiResMIR is the acronym of the Groupement de Recherche International (GDRI) called "High resolution microwave, infrared and Raman molecular spectroscopy for atmospheric, planetological and astrophysical applications".

The aim of this "Groupement" is to promote the exchange of ideas between researchers of eight laboratories belonging to five countries (Belgium, France, Germany, Italy, and Spain). Each institute brings its own worldwide-recognized expertise, complementary to the other HiResMIR partners. Broadly, these expertises are of two natures, centered on Molecular Spectroscopy and its application in atmospheric, planetological and astrophysical research.

Some of the HiResMIR members (Aachen, Bruxelles-ULB, Madrid, Namur, and Paris) are experts in the generation of accurate reference spectroscopic information (such as positions, intensities and shapes of spectral lines) for molecules of atmospheric, planetological and astrophysical interest. For that purpose, they combine various experimental high-resolution spectroscopic techniques (microwave, infrared or Raman) with high-level theoretical treatments.

Other HiResMIR partners (Bologna and IASB-BIRA) are concerned with the detailed study of the Earth and planetary atmospheres using optical remote sensing techniques. They are therefore users of reference spectroscopic parameters.

The multidisciplinary activities of the partners of the HiResMIR GDRI are therefore strongly linked. However, interactions between these two kinds of expert groups occur on too rare occasions. Discussions and exchanges of ideas to be promoted by the HiResMIR GDRI is an opportunity to contribute to filling this gap.


Current activities.

An international thematic school will be organized in the framework of this project in Fréjus from 3 to 7 June 2013. HiResMIR@CAES-Frejus-2013 will focus on high-resolution spectroscopy and its application for investigating physical or chemical processes taking place in the atmosphere of the Earth and of other planets as well as in the interstellar media.

 

SIROCCO

Started Nov 2012 - 18 month duration

SIROCCO is a 18-months ESA project focusing on "Development and performance assessment of synergetic retrieval algorithms for near-surface concentrations of CH4 and CO from SWIR and IR passive remote sensing measurements for Earth and Mars atmospheres".

The consortium is led by J. Chimot at NOVELTIS. It includes M. De Mazière's team at IASB-BIRA, J. Landgraf's team at SRON, P.-F. Coheur's team at ULB, M. Giuranna's team at IAPS and A.C. Vandaele's team at IASB-BIRA.

The study objectives are summarized here:

  • To specify the user requirements in terms of remote sensed Level 2 products (TIR and SWIR single measurements), derived from the user needs associated with clear applications for the two planets ;
  • To make a critical review of the already existing datasets and retrieval algorithms dedicated to CO and CH4 ;
  • To develop synergetic retrieval algorithms for deriving near-surface concentrations of CH4 and CO from SWIR and TIR passive remote sensing channels obtained by current and planned Earth and Mars satellite missions ;
  • To foster as much as possible the cross-fertilization between the Earth and planetary scientific expertise
  • To compare the usefulness and accuracy of the synergetic retrieval methods with the direct assimilation of SWIR and IR measurements in chemical transport models ;
  • To provide recommendations on the needs and specifications for co-located SWIR and IR measurements for the monitoring of near-surface CO and CH4 concentrations.

 

Venus Express and the SOIR instrument

Launched in 2005 - Lost in Dec. 2014

Venus Express is ESA's first mission to Earth's nearest planetary neighbour, Venus. The mission was born after ESA asked for proposals, in March 2001, suggesting how to reuse the design of the Mars Express spacecraft. Venus Express was launched in November 2005 and inserted into orbit around Venus in April 2006. The sapcecraft was finally loast in Dec. 2014.
IASB-BIRA is has designed the SOIR instrument, one of the 3 channels of the SPICAV/SOIR instrument on board Venus Express. IASB-BIRA was also responsible for the data pipeline and archiving of the SOIR data.


Current activities.

  • Archive : new batch (v4.0) ready for release to ESA

 

Mars Express and the SPICAM instrument

Launched in 2003

SPICAM is a space instrument onboard of ESA's mission Mars-Express, which has been orbiting around Mars since 2003. SPICAM has been observing since then and is still operating now. The instrument was partly built here at IASB-BIRA, in collaboration with the LATMOS (France) and IKI (Russia). It is a double spectrometer composed of an ultraviolet (UV) and a near-infrared (NIR) channel.
The UV channel is mainly used to measure Ozone, CO2, and O2 and the NIR channel is used to study water vapor, CO2 and O2. Other components/parameters can be estimated by analysing SPICAM data such as pressure, temperature, aerosol's loading (dust or clouds), surface properties, etc. SPICAM is able to work with different viewing mode, which are Nadir, Limb and solar/stellar occultation. These different viewing modes allow different types of results. For exemple, nadir gives good spatial coverage of the planet and is used to obtain mappings of the studied quantities. Limb or occultations do not have such a good spatial resolution but have the advantage to investigate the atmosphere at different altitudes.

We are developing at IASB-BIRA a retrieval algorithm in order to analyse the nadir UV data of SPICAM. The goal is to deduce the quantities of Ozone, aerosol's loading and surface albedo. We will obtain maps giving the evolution of these quantities over the period of SPICAM activity. We will also attempt to derive some optical properties of dust in the UV range. The developement of this retrieval program is also a preparation for the future missions. We will be ready to analyse data of the IASB-BIRA instrument's NOMAD which will be part of the future Trace Gas Orbiter mission.


Current activities. Preparation of the SPICAV/SPICAM Team Meeting, Catania, Sicily, June 16-19 2013 - Preliminary agenda available

 

Mars-GCM

The development of a Global Circulation Model (GCM) for the atmosphere of Mars started in 2006. The GM3 model developed at York University (Canada) was applied at BISA from 2007-2009. In 2010 BISA started to extend and redevelop the GCM under the name GEM-Mars.

ASIMUT - ALVL

ASIMUT is a modular program for radiative transfer calculations in planetary atmospheres. The ASIMUT software has been developed to exploit the synergy existing between the growing number of different instruments working under different geometries. The main particularities of the software are:

  • The possibility to retrieve columns and/or profiles of atmospheric constituents simultaneously from different spectra, which may have been recorded by different instruments or obtained under different geometries. This allows the possibility to perform combined retrieval, e.g., of a ground based measurement and a satellite-based one probing the same air mass, or from spectra recorded by different instruments on the same platform;
  • The analytical derivation of the Jacobians;
  • The use of the Optimal Estimation method (OEM), using diagonal or full covariance matrices;
  • Its portability;
  • Its modularity, hence the ease to add future features.
Initially developed for the Earth atmosphere, its applicability has been extended to extra-terrestrial atmospheres, such as those of Mars and Venus.

ASIMUT has been coupled to SPHER/TMATRIX and (V)LIDORT codes to include the complete treatment of the scattering effects into the radiative transfer calculations.

A more detailed description of the ASIMUT - ALVL software can be found here.



Current activities.
  • Version 10.0 frozen
  • Implementation of the latest f90 version of LIDORT to replace the old f77 version
