Vertically Integrated Water Vapour, Humidity and Temperature at Pressures Levels and Layers from ATOVS - Daily Means / Monthly Means

Abstract:
The CM SAF ATOVS data set offers 13 years (01 January 1999 - 31 December 2011) of water vapour and temperature satellite-derived global products. Different parameters generated simultaneously are available: vertically integrated water vapour (kg/m2), vertically integrated water vapour (kg/m2) and mean temperature (K) in 5 layers, specific humidity (g/kg) and temperature (K) on 6 levels. Also available are number of valid observations and an uncertainty estimate. The data set was derived from ATOVS onboard the NOAA satellites, NOAA-15, NOAA-16, NOAA-17, NOAA-18, NOAA-19 and onboard the European Metop-A satellite. ATOVS is composed of three instruments: HIRS, AMSU-B/MHS and AMSU-A. After application of a kriging routine, the products are available as daily and monthly means on a cylindrical equal area projection of 90km×90km. Grid information is given for centre position. Layers are (hPa): 200-300, 300-500, 500-700, 700-850, 850-surface. Levels are: 200, 300, 500, 700, 850, 1000 hPa. Products covered by this are: Vertically integrated water vapour, Layered water vapour and temperature , Specific humidity and temperature at pressure levels from ATOVS. This is a Thematic Climate Data Record (TCDR). The assigned DOI for this dataset is: 10.5676/EUM_SAF_CM/WVT_ATOVS/V001.
