Editor's Corner

Michael King—EOS Senior Project Scientist

All EOS AM-1, PM-1, ACRIM, Data Assimilation, LIS, SAGE III, and Sea Winds science teams developed Algorithm Theoretical Basis Documents (ATBDs) that were recently reviewed by peer review panels in November and December 1996, and March 1997. These documents, developed for each data product, consist of a detailed physical and mathematical description of the algorithm, variance or uncertainty estimates, and practical considerations, such as calibration and validation, exception handling, quality assessments, and diagnostics. In addition, seven of these teams have also developed validation plans that describe in considerable detail their pre-launch and post-launch validation activities. Once updates resulting from the written reviews and panel report recommendations are integrated, revised versions of these documents (80 ATBDs and 10 validation plans) will replace the older versions currently residing on the EOS Project Science Office Web site.

This peer review process is extraordinarily valuable to the science teams and engages the larger scientific community, both nationally and internationally, in the process of providing feedback on approaches to routine data reduction from EOS sensors.
