Surface Turbulent Fluxes, 1x1 deg Daily Grid, Satellite F13Entry ID: GES_DISC_GSSTF_F13_2b
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-progr...
This is a Daily (24-hour) product; data are projected to equidistant Grid that covers the globe at 1x1 degree cell size, resulting in data arrays of 360x180 size.
The daily fluxes are produced for each individual available SSM/I satellite tapes (e.g., F08, F10, F11, F13, F14 and F15), and then serve as input to the Combined daily fluxes (GES_DISC_GSSTF_2b).
These HDF-EOS5 files contain one grid that have 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 double quotes shows 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:

Quality Caution: Fluorometry is measured differently on each vessel and are thus not directly comparable between vessels. See the summary for further details.
The end of each sampling segment is geocoded with latitude and longitude calculated from the one minute time-stamped GPS data. "Segment Length" is the distance in nautical miles for each segment, which is calculated ... as the cumulative distance between each 1 minute interval. In theory, all segments are 5 nautical miles long. However, this wasn't always the case with early RSV Aurora Australis tows, where it was assumed that the silks advanced at a predetermined rate of 1 cm per nautical mile, whereas each tow had subtle variations in silk advancement, depending on local condition, e.g. whether the CPR was travelling with or against a current. True segment length has since been recalculated. At other times, some silks have been incorrectly cut and the true length has again been recalculated. The last segment of each tow is rarely exactly 5 nautical miles. It is usually less. In this situation we apply the following rule: if the last segment is longer than 2.5 nautical miles it remains as a segment in its own right and can be between 2.5 and 4.99 nautical miles, whereas if it is less than 2.5 it is added to the penultimate segment making the last segment 5 to 7.49 nautical miles. Users of the data can elect to dismiss the last segment. The "Segment Length" field can be used to standardise species counts. Dividing abundance values by the respective segment length will produce numbers per nautical mile, which is equivalent to 0.3 cubic metres based on 1 nautical mile being 1852 m multiplied by aperture area (12.7 x 12.7 mm). A 5 nautical segment is equivalent to 1.5 cubic metres.
