ATASF: Tri-hourly anomaly of tropical atmospheric surface fluxes.

<strong>ATASF dataset</strong> is a product that contains the tri-hourly surface anomalies of the entire tropical region (180°W - 178.125°E/33.3328°S – 31.4281°N) of the heat fluxes and of the incident and reflected radiation. These are calculated from 20th Century Reanalysis V2c data provided by the NOAA/OAR/ESRL PSD, Boulder, Colorado, USA, from their Web site at http://www.esrl.noaa.gov/psd/. This product contains the variables: Tri-hourly convective precipitation rate (kg m^{-2} s) Tri-hourly downward longwave radiation flux at surface (w m^{-2}) Tri-hourly downward solar radiation flux at surface (w m^{-2}) Tri-hourly upward longwave radiation flux at surface (w m^{-2}) Tri-hourly upward solar radiation flux at surface (w m^{-2}) Tri-hourly latent heat net flux at surface (w m^{-2}) Tri-hourly sensible heat net flux at surface (w m^{-2}) All these 3D grids have a period of time from 1851-01-01 00:00:00 to 2014-12-31 21:00:00, with a spatial resolution of 1.875 x 1.904732 degrees. The objective of this dataset is to facilitate researchers to study the anomalies of these 7 parameters on the ocean surface during the occurrence of short and medium duration physical processes such as low pressures, cold fronts, hurricanes and others.
