2008 New Release of Satellite Turbulent Fluxes

Published on 6 february 2008

The new turbulent fluxes are estimated using Fairall et al (2003) bulk algorithm. The resulting weekly and monthly 10-m wind speed (W), 10-m specific air humidity (Qa), 10-m air temperature (Ta), wind stress (tau), latent heat flux (LHF), and sensible heat (SHF) flux fields are first validated against weekly and monthly averaged in-situ data.
