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 <##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:
