Editor's Corner

Michael King, EOS Senior Project Scientist

l recently ereceived the repmt of the visiting committee that examined 13 algorithm theoretical basis documents (ATBDs) prepared by the ASTER, LIS, MO PITT, and Sea Winds Science Teams. The oral portion of this review followed a written review consisting of approximately 5 written reviews of each document. The Project Science Office has synthesized the inputs from both the written and oral reviews, visiting committee summaries, and discussion with some algorithm developers, team leaders, and the AM Project Scientist (Piers Sellers). As a consequence of this analysis, the at-launch/post-launch specifications for each product have been revised and clarified in greater detail. An overall indication of both the importance of the product(s) and the maturity of the algorithm(s) to date has been determined, with particular attention paid to the following categories addressed by the external reviewers: (i) degree to which product meets Mission to Planet Earth (MTPE) priorities, (ii) soundness (feasibility /practicality) of the algorithm's approach, and (iii) the planned schedule for generating useful at-launch products.

As done previously with the ATBD report and analysis for the MODIS, CERES and MISR Science Teams, each ATBD was placed into one of four categories. Revised algorithms for all category A and B ATBDs (those with a particularly sound basis, extreme relevance to global change research, and either minor or major modifi-...
