Description
The Interim Climate Data Record (ICDR) SEVIRI Clouds provides cloud properties derived from the SEVIRI sensor onboard METEOSAT second generation (MSG) satellites. It is the routinely continuation of the second edition of the CM SAF CLoud property dAtAset Using SEVIRI (CLAAS-2, DOI:10.5676/EUM_SAF_CM/CLAAS/V002), but only includes the product subset Cloud Fractional Cover (CFC) and Cloud Top Temperature/Pressure/Height (CTO). The ICDR SEVIRI Clouds features daily and monthly CFC/CTO averages aggregated on a regular 0.05° x 0.05° latitude/longitude grid. Monthly mean diurnal cycles on a 0.25° x 0.25° latitude/longitude grid are included as well. Although the algorithms used for the ICDR SEVIRI Clouds are identical to the ones used for CLAAS-2, some input data and intercalibration procedures had to be changed to facilitate a routine operation. Furthermore, a critical bug affecting monthly mean cloud top parameters in CLAAS-2 has been fixed for the ICDR SEVIRI Clouds. The ICDR SEVIRI Clouds is complemented with comprehensive documentation: Product User Manual (PUM), Validation Report (VAL) and Algorithm Theoretical Baseline Document (ATBD), find links below.
