Coordinate Variables and Time-stamps
Coordinate Variables
The coordinate variables of the WFDEI-GEM-CaPA simulations are
lon and lat representing the longitude and latitude points,
respectively.
Time-stamps
The time-stamps are included in the original files.
Dataset Variables
The list of variables included in the dataset is descriped in Short Description on Dataset Variables
Spatial Extent
The spatial extent of the dataset is on latitutes from 31.0625 to
71.9375 and longitudes from -149.9375 to -50.0625 covering
North America. The resolution is 0.125 degrees.
Temporal Extent
The time-steps are 3-hourly covering from January 1951 to
December 2100.
Short Description on Dataset Variables
In most hydrological modelling applications, usually 7 variables are
needed detailed as following: 1) specific humidity at 40 meters, 2)
surface pressure, 3) air temperature at 40 meters, 4) wind speed at 40
meters, 5) precipitation, 6) downward short wave radiation, and 7)
downward long wave radiation. These variables are available through
WFDEI-GEM-CaPA dataset and their details are described in the table
below:
