The Use and Usability of Satellite Data for Tropospheric Research

Report from the fifth Workshop

The fifth TROPOSAT workshop took place in the Kongresszentrum Garmisch-Partenkirchen on Wednesday 13th March 2002


1. Welcome. The workshop opened at 09.00 with a welcome from the subproject coordinator, Ulrich Platt, for the 52 PIs, students and guests attending. An attendance list is attached.

2. TROPOSAT: present status. The subproject coordinator; Ulrich Platt, reported briefly on the current situation which was satisfactory. He emphasised that the point of the present workshop was to outline a plan for the future of the project when it comes to its formal end in the Spring of 2003.

3. News

a. ENVISAT instruments

SCIAMACHY: John Burrows (Deputy Coordinator) reported that ENVISAT had been launched successfully into an excellent orbit on February 28th/March 1st. The instruments were out-gassing at present and would be switched on gradually during the next few weeks. The first data is expected in July 2002 and the first data products should be released generally in the second half of 2002. There is a web page now devoted to SCIAMACHY:

MIPAS: Gabrielle Stiller (PI, task group 1) reported that MIPAS will be switched on in about two weeks (end of calendar week 12) and that the first data for Cal/Val activities are expected in June. Geophysical data should be available at the beginning of 2003.

b. TROPOSAT, Peter Borrell, deputy coordinator, reported the following.

Items from the last meeting

4. Structure of the TROPOSAT Final Report and allotment of tasks. The appended structure was largely that supplied to the ISS. The following points were made about the report.

*5. The future.

a. Future of EUROTRAC: Ulrich Platt, subproject coordinator, introduced a summary of the paper prepared by Ǿystein Hov on a possible project to follow EUROTRAC-2. It advocated a move from atmospheric pollution to atmospheric sustainability and proposed a project named

EUROTRAC-Atmospheric Composition Sustainability or EUROTRAC-ACT.

b. Future possibilities for TROPOSAT: John Burrows, deputy coordinator, introduced a number of points and suggestions.

i. Good quality annual and final reports are essential if TROPOSAT is to continue.

ii. A proposal will be made to ESRIN to prolong the support for the co-ordination of TROPOSAT which we have enjoyed in the first phase. The aim will be to exploit fully the new data becoming available from the various satellites, preferably in combination with modelling, ground based and flight initiatives to explore scientific and technical problems of current interest, such as aerosols, stratosphere/troposphere exchange and enhancement of air quality.

iii. The possibility of having TROPOSAT explicitly included in the Global Measurement of Environment and Sustainability (GMES), a joint EU/ESA/EUMETSAT initiative will be explored.

iv. TROPOSAT would seem to be well placed to take advantage of the new EU initiative establishing "networks of excellence" within Europe. It is expected that a first call will be made shortly and it has been suggested that some 50000 per annum will be available to groups participating in an approved network.

v. The first call for proposals for the 6th EU Framework programme is expected at the beginning of 2003.

6. Presentations by leaders of task group 1. Andreas Richter and Thomas Wagner.

Progress is satisfactory and most annual reports have been received. Not much validation has been done yet.

7. Presentations by leader of task group 2. Martin Dameris.

Good progress with nice examples emerging.

8. Presentations by leaders of task group 3. Hermann Smit and Paul Monks.

Need to develop a strategy for integrated observation. PIs from all groups should contribute if they are doing "synergistic " work.

9. Presentations by leader of task group 4. Albert Goede on behalf of Hennie Kelder.

Reasonable progress. It is hoped to produce a list of data which suitable for satellite data validation purposes.

10. Presentations on Underpinning activities

a. Specifications for future satellite instrumentation, Albert Goede.

The proposal for GeoTROPE is under review as is the EU GMES proposal.

There will be an ESA GMES call for proposals later in the year.

b. Data assimilation techniques, Hendrik Elbern.

PIs engaged in data assimilation had been approached but only one had responded. Two techniques were being explored: the Kalmann filter (Builtjes) and 4-D data assimilation (Elbern).

11. Future Activities

Next TROPOSAT workshop: 21st & 22nd November, KNMI, de Built, NL.

Final Workshop of this phase: ESRIN, Frascati, I; March 2003

12. Summing up & closing remarks: John Burrows, deputy coordinator, expressed the view that it had been a most successful workshop. The future was now a bit clearer. If only some of the actions planned came off we would be able to extend into a second phase. Ulrich Platt, coordinator, closed the meeting at 12.30 with thanks to the PIs and guests attending.
