  1. The GHRSST_PPALADIN 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
