Coordinate Variables and Time-stamps
Coordinate Variables
The coordinate variables of the RDRSv2.1 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 NetCDF files of the dataset contain 28 variables. You may see a list
of variables by using the ncdump -h command on one of the files:
foo@bar:~$ module load cdo/2.0.4
foo@bar:~$ module load nco/5.0.6
foo@bar:~$ ncdump -h /project/rpp-kshook/Model_Output/RDRSv2.1/1980/1980010112.nc
Spatial Extent
The spatial extent of the RDRS v2.1 is on latitutes from +5.75
to +64.75 and longitudes from -179.9925 to 179.9728 covering
North America. The resolution is 0.09 degrees (~10km).
Temporal Extent
The time-steps are hourly covering from January 1980 to
December 2018.
Short Description on RDRS v2.1 Variables
In most hydrological modelling applications, usually 7 variables are
needed detailed as following: 1) specific humidity (@1.5-2.0m or @40m),
2) surface pressure, 3) air temperature (@1.5m-2.0m or 40m), 4) wind
speed (@10m or @40m), 5) precipitation (surface level), 6) downward
short wave radiation (surface level), and 7) downward long wave
radiation (surface level). These variables are available through
RDRS v2.1 dataset and their details are described in the table
below:
