Summary
Abstract: These data are the Goddard Satellite-based Surface Turbulent Fluxes Version-2b (GSSTF2b) Dataset recently produced through a MEaSURES funded project led by Dr. Chung-Lin Shie (UMBC/GEST, NASA/GSFC), converted to HDF-EOS5 format. The stewardship of this HDF-EOS5 dataset is part of the MEaSUREs project, http://earthdata.nasa.gov/our-community/community-data-system-programs/measures-projects/surface-turbulent-fluxes-esdr

This is the Yearly Climatology product; data are projected to equidistant Grid that covers the globe at 1x1 degree cell size, resulting in data arrays of 360x180 size. The yearly product is a result of averaging of monthly climatologies, GES_DISC_GSSTFMC_2b. As with the Daily product, there are two sets of Combined data, "Set1" and "Set2". They are different for being produced using a different combination of individual satellite products. Set1/Set2 may contain a larger/smaller global temporal trend in latent heat flux, but with less/more missing data. They are stored together in the yearly HDF-EOS5 files, under two separate Grids, SET1 and SET2. The Yearly Climatology HDF-EOS5 file also contains one extra grid of NCEP Climatology, "NCEP".

SET1 and SET2 grids each contain 9 variables:

"E" 'latent heat flux' (W/m**2),
"STu" 'zonal wind stress' (N/m**2),
"STv" 'meridional wind stress' (N/m**2),
"H" 'sensible heat flux' (W/m**2),
"Qair" 'surface air (~10-m) specific humidity' (g/kg),
"WB" 'lowest 500-m precipitable water' (g/cm**2),
"U" '10-m wind speed' (m/s),
"DQ" 'sea-air humidity difference' (g/kg)
"Tot_Precip_Water" 'total precipitable water' (g/cm**2)

The NCEP grid contains 4 variables:
"SST" 'sea surface skin temperature' (C)
"Psea_level" 'sea level pressure' (hPa)
"Tair_2m" '2m air temperature' (C)
"Qsat" 'sea surface saturation humidity' (g/kg)

The double-quoted labels are the short names of the data fields in the HDF-EOS5 files.


The GSSTF2b was originally released in binary format, and more details on the methodology, and relevant references, can be found here:

The previous GSSTF dataset (GSSTF2) has been widely used by scientific communities for global energy and water cycle research and regional and short period data analysis since its official release in 2000/2001. Accurate sea surface fluxes measurements are crucial to understanding the global water and energy cycles. The oceanic evaporation that is a major component of the global oceanic fresh water flux is particularly useful to predicting oceanic circulation and transport. Remote sensing is a valuable tool for global monitoring of these flux measurements. The GSSTF algorithm has been developed and applied to remote sensing research and applications. We are looking forward to serving the scientific communities with another useful dataset in GSSTF2b.
