Summary
Abstract:
This data set contains a series of land surface parameters simulated from the Catchment model experiment 001, for Version 2 of the Global Land Data Assimilation System (GLDAS-2). The data are in 1.0 degree resolution and range from January 1948 to the present. The temporal resolution is 3 hourly. The model simulation was initialized on simulation date January 1, 1948, using soil moisture and ... other state fields from the LSM climatology for that day of the year. The simulation was forced by the global meteorological forcing data set from Princeton University (Sheffield et al., 2006). The simulation used the common GLDAS data sets for land cover (UMD: Hansen, 2000), soil texture (Reynolds, 1999), and elevation (GTOPO30).
The main objective for Version 2 is to create more climatologically consistent data sets using the Princeton forcing data sets extending from 1948. In Version 1, forcing sources switched several times throughout the record from 1979 to present, which introduced unnatural trends and exhibited highly uncertain forcing fields in 1995-1997. Other enhancements made in Version 2 include initialization of soil moisture over desert and bottom layer temperature.
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 numbers. The following table shows a list of parameters, their Product Definition Section (PDS) IDs and units.

Quality
Current Water Year data provided by the Washington State Department of
Ecology - including stream discharge and water level values are
automatically generated by remote equipment and have not been reviewed
or edited for accuracy. Inaccuracies in the data may be present due
to instrument malfunctions or physical changes to the discharge
measurement sites. End of water year review may result in significant
revisions to the data.
Access Constraints
The operation of Ecology stream flow stations falls into three types:
Telemetry, Stand Alone, and Manual Stage Height. The specific type
determines the availability of data for each stream flow station.
Use Constraints
None
