< 6th TROPOSAT workshop



The Use and Usability of Satellite Data for Tropospheric Research

Report from the 7th Workshop


The seventh workshop took place in the Main Conference Room at ESA/ESRIN,
Frascati Italy on Thursday and Friday 8th & 9th of May 2003

Workshop Report

1.         Welcome, approval of the agenda. Ulrich Platt, the subproject coordinator opened the workshop at 11.15 with a welcome for the 27 participants present. A list of those attending and who sent apologies is attached. The agenda, which had been previously circulated was approved. Claus Zehner added a welcome on behalf of ESRIN.

2.         External initiatives for the future

a.         TROPOSAT and ACCENT. John Burrows, deputy coordinator, described the structure of the network of excellence, ACCENT, a proposal for which had been submitted to the European Commission (EC) by the coordinator Sandro Fuzzi and a group of European atmospheric scientists.

-           It is expected that the TROPOSAT community will contribute to the tasks on remote sensing, modelling and intercomparisons.

-           There are only 15 partners in the network but it was expected that the other participants would be included as "associate" partners with the same accessibility as the partners.

-           It is hoped that there would be funds available to help with the coordination and to run workshops etc.

-           The proposal should be decided later in 2003.

« -      The workshop thanked John Burrows for the time and effort he had spent in securing the admission of the community to ACCENT.

Note item 4, below, on the future of TROPOSAT

b.         ESF Workshop. Peter Borrell reported that a draft application had been prepared to hold a workshop, sponsored by the European Science Foundation (ESF). The deadline had now passed for 2004.

« -      The application should be held over until 2004.

c.         European Physical Society. Albert Goede reported that the EPS sponsors workshops and that it might be worthwhile to take advantage of their facilities.

d.         GMES. Albert Goede, reported that several proposals had been made to ESA to deliver operational products for GMES. None had been selected, mainly on the grounds that there was little contribution of the potential users of the data products to the proposals.

3.         News and Reports

a.         ESA/ESRIN. activities and plans. Claus Zehner reported that ways were being explored to interact more with the users of the data, and that user requirements would figure largely in the selection of future missions.

It was pointed out that exclusive concentration on immediate users of data would stifle the scientific initiatives which had lead to such successful long term projects in the past.

ESA expected a final report from TROPOSAT in the near future in addition to that being published by Springer (see below). It should address the questions in the proposal and should specify if possible future needs and organisational lessons.

« -      Peter Borrell was asked to circulate the group to ascertain future needs and include the results in the final report that he would be preparing in July.

b.         SCIAMACHY. John Burrows reported that:

-           the instrument is working well and delivering good data to the ground;

-           several scientific groups were making their own validation of the raw data and producing scientific results which demonstrated the success of the mission;

-           unfortunately there are still problems with the delivery of the official data products and with the contracts of the groups employed to validate the official data;

-           it is expected that data of improved quality will be released before the end of 2003 (one year late);

-           it is hoped that the initial validation will be complete by the end of 2004.

The discussion highlighted problems experienced by principal investigators who have short-term national contracts to use the data

« -      Principal investigators with short-term national contracts who have problems with the delivery of data should contact the ENVISAT Mission Manager for a supporting statement of the situation to support their cases for extensions to the national funding agencies.

c.         MIPAS. Gabrielle Stiller reported that:

-           the situation had much improved since the previous workshop;

-           the target height uncertainty was much reduced but may still have a small bias;

-           it is hoped that the level 1 products would be released in June 2003,

-           it is hoped to have level 2 products by the end of the year;

-           early results gave O3, ClO and ClONO2 for the polar vortex in 2002.

d.         TROPOSAT final report. Patricia Borrell thanked everyone for providing the material promptly. However Springer, the publisher, had their own format so that it had been necessary to re-edit the whole book in fine detail. In fact, we seemed to be doing everything except actually printing it!

Peter Borrell reported that the book would probably go for printing at the beginning of June. The costs (ca €4000) were being paid by the Bremen & Heidelberg groups.

The overview had been printed in volume 2 of the EUROTRAC-2 final report in February, 2003. A comment was made that it was a pity that the individual authors names had been relegated to the end of the TROPOSAT contribution.

«        The meeting thanked Patricia and Peter Borrell for their sustained efforts to publish the final report.

e.         EGS Session on instrumentation: Gabrielle Stiller reported that there had been about one hundred presentations and posters, mainly on GOME, SCIAMACHY and MIPAS results. It was reckoned to be a most successful session.

f.          IGACO. Peter Borrell reported that he and John Burrows had attended the second meeting at the WMO in Geneva. A theme report is being prepared which should set the scene for global observation of the troposphere for the next ten years. Peter Borrell has been employed to help with the writing and to edit the various drafts.

It was commented that the integration of data from different platforms and models would be easier if a common format could be devised to accommodate the information from the diverse sources.

i.          Geostationary satellite. John Burrows reported that:

-           the proposal for GeoTROPE is in limbo;

-           it is possible that continuation studies will take place;

-           the German government is considering funding a geostationary earth observation satellite (this would use funds that could have gone to GEOTROPE).

4.         Future TROPOSAT organisation and activities. There was prolonged and vigorous discussion on the possibilities for the future and the relationship to accent. The general tenor was that TROPOSAT should be continued and the following resolutions were passed.

«        There should be a TROPOSAT Phase 2, which would be a new project.

«        Present principal investigators and others interested would be invited, later in the year, to provide a single page statement of their proposed work in order to apply to join.

«        There should be three task groups – algorithms, uses and validation (presently 1,2 & 4).

«        A decision should be made later about dispersing the present task group 3 (synergy) between the other groups or forming a fourth task group.

«        A decision should be made later about whether to subsume the present underpinning activity of data assimilation in the present task groups 2(uses) and 4 (validation).

«        There should be an associated activity to define "Future needs for satellite data for atmospheric research and monitoring".

«        The first meeting of the TROPOSAT-2 would take place on the 19th & 20th February 2004 in Heidelberg.

«        It was recognised that some of the decisions might have to be modified if ACCENT is approved.

The immediate action now required are as follows.

«        Each of the present task groups should provide, before 30th September 2003, Peter Borrell with the following

a.         a list of achievable aims on two time scales:

i.          short term (18months) for use with ACCENT if approved;

ii.         long term (3 to 5years) for use with TROPOSAT-2.

b.         any suggestions for the future organisation of the project or task groups. (e.g. should task goup 1 have "subgroups"; should task group 2 have "cross cutting tasks"; should task group 3 be distributed; should data assimilation be "assimilated"?)

«        The following principal investigators and task group leaders were delegated to provide the information requested in the preceding item before 30th September 2003. The agreement of the principal investigators marked with an asterisk* was obtained from their representatives. PIs who were not at the meeting are invited to contribute too.
