Abstract:

This data set contains a series of land surface parameters simulated from the Variable Infiltration Capacity (VIC) Model in the Global Land Data Assimilation System (GLDAS). The data are in 1.0 degree resolution and range from 1979 to the present. The temporal resolution is 3-hour. This simulation was forced by combination of NOAA/GDAS atmospheric analysis fields, spatially and temporally disaggregated NOAA Climate Prediction Center Merged Analysis of Precipitation (CMAP) fields, and observation based downward shortwave and longwave radiation fields derived using the method of the Air Force Weather Agency's AGRicultural METeorological modeling system (AGRMET). The simulation was initialized on 1 January 1979 using soil moisture and other state fields from a GLDAS/VIC model climatology for that day of the year. WGRIB or other GRIB reader is required to read the files. The data set applies a user-defined parameter table to indicate the contents and parameter number. The following table shows a list of parameters, their Product Definition Section (PDS) IDs and units. PDS_IDs Full_Name Unit 001 Surface pressure Pa 011 Near surface air temperature K 032 Near surface wind magnitude m/s 051 Near surface specific humidity kg/kg 057 Total evapotranspiration kg/m^2 065 Snow water equivalent kg/m^2 071 Total canopy water storage kg/m^2 085 Average layer soil temperature K 086 Average layer soil moisture kg/m^2 099 Snowmelt kg/m^2 111 Net shortwave radiation W/m^2 112 Net longwave radiation W/m^2 121 Latent heat flux W/m^2 122 Sensible heat flux W/m^2 131 Snowfall rate kg/m^2/s 132 Rainfall rate kg/m^2/s 138 Average surface temperature K 155 Ground heat flux W/m^2 204 Surface incident shortwave radiation W/m^2 205 Surface incident longwave radiation W/m^2 234 Subsurface runoff kg/m^2 235 Surface runoff kg/m^2 There are 3 vertical levels each for the Soil Moisture (PDS 086) and Soil Temperature (PDS 085) in the GRIB file.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The data are provisional and subject to change as model improvements are implemented and new input data sets become available. Due to the fact that forcing data for Greenland are unreliable and the lack of a glacier/ice sheet model, snow water equivalent accumulates indefinitely in Greenland and a few other Arctic points. Therefore it is highly recommended that Greenland and other points with abnormally large snow water equivalent values be masked out when performing global analyses.
