The MPIC/DLR climate water vapor product

Project: GOME Evolution - Within the ESA GOME Evolution project, two different total column water vapor (TCWV) products are developed and applied to the satellite instruments GOME, SCIAMACHY, and GOME-2: 1. The "climate" product with focus on consistent time series of monthly means 2. The "advanced AMF algorithm" (A3) product with focus on accurate retrievals for individual pixels. The GOME Evolution project is funded by European Space Agency (ESA) under contract no. 4000110429 Summary: The MPIC/DLR "climate" water vapor product, developed within ESA's "GOME Evolution" project, provides a consistent time series of monthly mean H2O columns from the satellite instruments GOME, SCIAMACHY, and GOME-2 (MetopA). Consistency amongst the different instruments (including cloud treatment) is substantially improved by (1) merging SCIAMACHY and GOME-2 observations to GOME pixel size, and (2) reducing the GOME-2 swath width to GOME/SCIAMACHY swath, thereby mimicking GOME-like observation conditions for all three sensors. WARNING: Version 1.0 is based on spectral analysis settings which have slightly changed during the GOME-2 timeseries, introducing a small but clear "jump" in the TCWV timeseries at the turn of the years 2012/2013. This version should not be used any more! Use version >2.2 instead! doi:10.1594/WDCC/GOME-EVL_water_vapor_clim_v2.2
