1. L4 SST analysis of Diurnal cycle J. Tournadre, J.F. Piollé, E. Autret IFREMER, Laboratoire d’Océanographie Spatiale

2. L4 FIELDS Daily 2km SST foundation Can we use the L4 SST fields as a base to analyse the SST variations during day and night. Seviri : L2P field every 3 hours Analysis of Seviri L2PSST – L4 SST as a function of time difference from Analysis time

3. Night time analysis for two period Seviri –L4 Two periods March 2006 May 2006 Weak night cooling 0.2 K during the night - 5h +5h - 5h +5h Strong night cooling >0.4 K during the night

4. Analysis of diurnal warming Seviri –L4 Max - min

5. Annual DW
