Europe: Cloud top height
Cloud Top Height (CTH) is part of the Cloud Products (CRR) which is one of the EUMESAT ‘s (European Organisation for the Exploitation of Meteorological Satellites) SAF NWC (Satellite Application Facility on support to Nowcasting) products. The National Observatory of Athens has installed and operates the 2013 version, since 2015.
CTH is estimated every 15 minutes, using imagery from the geostationary meteorological satellite Meteosat and auxiliary data from the non-hydrological numerical model WRF v3.6.1 (Weather Research and Forecasting Model). CTH is an instant parameter, providing the height of the cloud top at the nominal time of the satellite image.
