GEOS Forward Processing (GEOS-FP) patch May 22, 2024


GEOS-5.29.5-p6 was implemented starting with the 12:00 UTC cycle on May 22, 2024. An update was made to the assimilation system that improves the use of several microwave data-types and incorporates an additional source of ozone data. The changes include an improvement to the data-selection process for bias-correcting GMI radiances; reinitialization of the bias correction coefficients for AMSU-A and ATMS radiances; and active assimilation of OMPS-LP ozone observations (which were previously implemented as a passive data-type). Collectively, these changes provide a small but measurable improvement in the overall quality of the analysis.
