1. The GHRSST_PP ALADIN DW data base Emmanuelle Autret*, Mark Fillipiak**, Pierre LeBorgne***, Hervé Roquet*** *Ifremer, Brest; **Univ. of Edinburgh; ***M-F/CMS, Lannion Presented at the 8th GHRSST meeting, Melbourne, Australia, May 2007

2. Foreword  The ALADIN model outputs available in this database have been provided by Météo-France on request of the Director of the GHRSST-PP Projret Office (Craig Donlon) and are restricted to research activities within the GHRSST-PP.  Database available though: ftp://ftp.ifremer.fr/ifremer/cersat/projects/ghrsst-dvwg/aladin-dw/

3. Data base content overview  Coverage 35N-55N; 11W_17E, 0.1° resolution  Daily files from the 1st April till the 30th September 2006  lat,lon  landmask, analyzed_sst) HOURLY VARIABLES:  ALADIN outputs (U_wind, V_wind, net_ssi, net_dli, latent_heat, sensible_heat)  ECMWF* outputs (as above)  mw wind (speed, time, origin)  dt_analysis (DT, error)  reference SST  MSG derived radiative fluxes (ssi, dli)  MSG derived Saharan Dust Index (sdi) *ECMWF fluxes at 6, 12, 18 and 24 only
