Coordinate Variables and Time-stamps
Coordinate Variables
The coordinate variables of the CanRCM4-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
Each NetCDF file belongs to a single variable. 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 the Lowest Model
Level (sigma=0.995), 2) surface pressure, 3) air temperature at the
Lowest Model Level, 4) wind speed at the Lowest Model Level
(sigma=0.995), 5) precipitation, 6) downward short wave radiation, and
7) downward long wave radiation. These variables are available through
CanRCM4-WFDEI-GEM-CaPA dataset and their details are described in
the table below:
