CCRN CanRCM4-WFDEI-GEM-CaPA

In this file, the details of the dataset is explained.

Location of Dataset Files

The CanRCM4-WFDEI-GEM-CaPA dataset is located under the following directory accessible from Digital Alliance of Canada (formerly Compute Canada) Graham cluster:

/project/rpp-kshook/Model_Output/280_CanRCM4_Cor_WFDEI-GEM-CaPA

and the structure of the dataset hourly files is as following:

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:
