Decisions

  • Invitations to external experts for the Feb 2010 GSICS meeting in Toulouse will be limited to 1 for ATSR and 1 for microwave instruments, plus 1 or 2 from the ARA group of Chedin and Scott.
  • T. Hewison's proposal to invite David Llewellyn-Jones (University of Leicester) as an ATSR expert was supported.
  • It is more difficult to identify a single expert to represent both microwave sounder and imager inter-calibration. This will be done by email outside the meeting.
  • It was agreed that GPRCs are free to include additional data in the GSICS Correction Coefficients files for their instruments (for example Look-Up Tables to convert counts to brightness temperatures) SO LONG AS the basic regression-based correction coefficients (and their covariances) are specified in the file in terms of radiances.
  • It was agreed to refer to the instrument for which calibration corrections are being produced as the Monitored Instrument (MON for short) and the instrument providing the calibration reference as the Reference Instrument (REF for short).
  • The question of whether correction coefficients applicable to extended time periods should be included in a single file will be defered until the Toulouse meeting (as opposed to including results for only 1 time period in each file).
  • In terms of the GSICS Product Acceptance Procedure (GPPA), each instrument pair being considered forms a new product and each new product must be complete the GPPA.
  • The GPPA should be tested with a "guinea pig" product. Progress will be reported at the Toulouse meeting. The outcome of the test of the GPPA should be reported to the next GSICS Exec Panel in April 2010.
  • A standard acknowledgement paragraph should be provided with every GSICS product, which authors should be obligued to include when they publish any results which use GSICS products.

Actions

  1. X. Wu to check with M.Goldberg whether minutes of UsersWorkshop2009 were approved by Executive Panel for circulation to attendees.
  2. D. Blumstein to advise whether it will be possible for participants to attend the Toulouse meeting remotely by teleconference.
  3. D. Blumstein to issue invitation to David Llewellyn-Jones (University of Leicester) identify an ATSR calibration expert to attend Toulouse meeting.
  4. T. Hewison, B. Iacovazzi, X. Wu and F. Weng to identify and invite external expert able to present issues of microwave instrument inter-calibration by teleconference at Toulouse meeting.
  5. T. Hewison to circulate proposal for the number of ATBD steps to all GRWG and GDWG for approval/objection by 8 December 2009.
  6. A. Jelenak to provide demonstration of Wiki-based ATBD documentation system at Toulouse meeting.
  7. B. Iacovazzi to resend GSICS Products Roster to GRWG and GDWG for review at Tolouse.
  8. T. Hewison to set up a new web meeting dedicated to the discussion of the strategy for inter-calibration of solar channels. This should be held on 8 December 2009. B.J. Sohn and CNES should be invited to attend.
  9. V. Gärtner to set up another web meeting to review the agenda in preparation for the Toulouse meeting. A tentative date of 26 Jan 2010 was set for this meeting.
