The 11th Tropospheric Emission Spectrometer (TES) Science Team meeting was held at the San Juan Institute in San Juan Capistrano, CA, on May 24 1995, preceded by the Data Analysis Working Group (DAWG) on May 23.
Larry Sparks began the DAWG meeting with a discussion of the latest improvements in Sequential Evaluation Algorithm For Simultaneous and Concurrent Retrieval of Atmospheric Parameter Estimates (SEASCRAPE), among which is an improved memory management scheme that has significantly improved the speed of the algorithm.
Tony Clough showed that pre-computing absorption coefficient tables have had a major impact on the speed of the line-by-line radiative transfer model (LBLRTM) algorithm. The subsequent discussion led to a decision that we should convene a special meeting of solely the formal co-investigators to discuss both this subject and the possible development of a joint "community" algorithm whose elements would be "owned" by individual team members, thereby giving them a greater stake in this entire process [this meeting was subsequently held in Denver in late June]. It was further decided that the DAWG has outlived its usefulness. Instead, the Co-Is will meet in executive session at all future team meetings in order to lay plans for the following months and will have a monthly teleconference starting in the fall. The rest of this final DAWG session was primarily given over to discussions of the status of the spectroscopic databases, including the beta release of HITRAN 1995.
At the main, open session on the 24th, following a TES & Airborne Emission Spectrometer (AES) project update by Tom Glavich, most of the day was given over to a discussion of the Work Package Agreements between the TES project and the co-investigators. In view of the previous day's discussion, it was not possible to reach closure on this issue, and it is clear that the topic will require further discussion at the next team meeting.
Helen Worden described the analysis of last year's AES wildfire data that pointed to several deficiencies in the existing spectral databases when high-temperature sources such as fires are being observed. This work, which was presented earlier at the Chapman Conference on Biomass Burning in Williamsburg, VA (March 13-17, 1995), is now complete and is currently being prepared for publication in the Journal of Geophysical Research.
It was agreed that the next team meeting will be held in Cambridge, MA, at Atmospheric Environmental Research, Inc. on November 7-9, 1995.
