What ‘s up since we met in Paris ?<br />

Cloud maks and properties from GEO: validation with CALIOP<br />

The elaboration <strong>of</strong> coherent cloud mask, cloud type classification and cloud top pressure maps with a<br />

high spatial and temporal resolution in the tropics using geostationary satellite data (GOES-E, GOES-W,<br />

MTSAT and SEVIRI/Meteosat) and the SAFNWC algorithm.<br />

An evaluation <strong>of</strong> these clouds fields: comparison <strong>of</strong> cloud cover, cloud cover types and cloud top<br />

pressure with CALIOP lidar data. Use <strong>of</strong> mean and instantaneous statistics (G. Sèze et al., to submit to<br />

QJRMS)<br />
