Cloud Products Inter-comparison exercise:
Temperature and humidity sounding data are now assimilated in clear conditions at many operational meteorological centers, providing good impact on forecast skill. However more than 80% on the whole globe is covered by clouds and NWP centers began to handle cloud-affected data, the first step being to detect and characterize the clouds in the footprint of the sounder.
One way of investigating the limitations of a particular methodology is to perform a careful inter-comparison of the results of different processing schemes for the same observations. For this exercise, cloud detection and characterization schemes from NOAA, EUMETSAT, NRL, LMD, MetOffice, Météo-France/CMS, Météo-France/GMAP and CMC centers were applied to a 12 hour global METOP acquisition on 18 November 2009.
