Abstract

The The FIDelity and Uncertainty in Climate data records from Earth Observations (FIDUCEO) project Upper Tropospheric Humidity (UTH) Climate Data Record version 1.2 dataset is derived from satellite brightness temperatures and uncertainties from the FIDUCEO Microwave Fundamental Climate Data Record (FCDR). The instantaneous observations from the FIDUCEO Microwave FCDR are used to derive a spatio-temporal averaged data record, which contains monthly mean UTH and brightness temperature mapped to a regular latitude/longitude grid covering the tropical region (-30° to 30° N), with a spatial resolution of 1° x 1°. It covers all mission years of the Special Senson Microwave for Temperature (SSMT2) instrument on the F11, F12, F14, F15 satellites, the Advanced Mircowave Sounding Unit (AMSU-B ) instrument on the NOAA 15-17 satellites and the Microwave Humidity Sounder (MHS) instruments on the NOAA18, NOAA19, MetopA, Metop-B satellites.

File Format:
The file format is netCDF, and each UTH CDR file for this version contains:Longitudes and Latitudes of grid cell centres and grid cell boundaries; Observation and satellite overpass counts for ascending and descending branches; Earliest and latest time of day of pixel contribution to the monthly average, for ascending and descending branches;; Monthly average and standard deviation of 183.31±1 GHz brightness temperatures that were used to derive UTH (excluding cloudy pixels), for ascending and descending branches;Monthly average of all 183.31±1 GHzbrightness temperatures (including cloudy pixels), for ascending and descending branches;Monthly average and standard deviation of UTH (derived from channel 3 brightness temperatures);Independent, structured and common uncertainty for monthly averages of brightness temperatures and UTH, for ascending and descending branches;The dimensions of the variables in the NetCDF file are xand y, indicating east-west and north-south direction, respectively. For further information see thefile format specification in the documentation.
