The ESA GOME-Evolution “Climate” water vapor product: a homogenized time series of H<sub>2</sub>O columns from GOME, SCIAMACHY, and GOME-2
We present time series of the global distribution of water vapor columns over more than 2 decades based on measurements from the satellite instruments GOME, SCIAMACHY, and GOME-2 in the red spectral range. A particular focus is the consistency amongst the different sensors to avoid jumps from on...

| description | We present time series of the global distribution of water vapor
columns over more than 2 decades based on measurements from the satellite
instruments GOME, SCIAMACHY, and GOME-2 in the red spectral range. A particular
focus is the consistency amongst the different sensors to avoid jumps from
one instrument to another. This is reached by applying robust and simple
retrieval settings consistently. Potentially systematic effects due to
differences in ground pixel size are avoided by merging SCIAMACHY and GOME-2
observations to GOME spatial resolution, which also allows for a consistent
treatment of cloud effects. In addition, the GOME-2 swath is reduced to that
of GOME and SCIAMACHY to have consistent viewing geometries.<br><br>Remaining systematic differences between the different sensors are
investigated during overlap periods and are corrected for in the homogenized
time series. The resulting <q>Climate</q> product v2.2 (<a href="https://doi.org/10.1594/WDCC/GOME-EVL_water_vapor_clim_v2.2" target="_blank">https://doi.org/10.1594/WDCC/GOME-EVL_water_vapor_clim_v2.2</a>) allows the study of the temporal evolution of water vapor over the
last 20 years on a global scale. |
