Alberta Government Climate Dataset (ab-gov)

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

Location of Dataset Files

The ab-gov dataset is located under the following directories accessible from Compute Canada (CC) Graham Cluster:

/project/rpp-kshook/Climate_Forcing_Data/meteorological-data/ab-gov # rpp-kshook allocation
/project/rrg-mclark/data/meteorological-data/ab-gov # rrg-mclark allocation

and the structure of the dataset yearly files (containing daily time-steps) is as following:

ab-gov Climate Models

This dataset offers outputs of various climate models. Table below summarizes the models and relevant keywords that could be used with the main datatool script:

# Model (keyword for --model) Scenarios (keyword for --scenario)
1 BCC-CSM2-MR historical, ssp126, ssp370
2 CNRM-CM6-1 historical, ssp126, ssp585
3 EC-Earth3-Veg historical, ssp126, ssp370
4 GFDL-CM4 historical, ssp245
5 GFDL-ESM4 historical, ssp585
6 IPSL-CM6A-LR historical, ssp126, ssp370
7 MRI-ESM2-0 historical, ssp370, ssp585
8 Hybrid-observation no keyword necessary

Coordinate Variables, Spatial and Temporal extents, and Time-stamps

Coordinate Variables

The coordinate variables of the ab-gov climate dataset files are lon and lat representing the longitude and latitude points, respectively.

Temporal Extents and Time-stamps

The time-stamps are already included in the original files. The dataset offers daily time-series of climate variables. The following table describes the temporal extent for senarios included in this dataset:

# Scenarios (keyword for --scenario) Temporal extent
1 historical 1950-01-02 to 2015-01-01
2 ssp126 2015-01-02 to 2101-01-01
3 ssp245 2015-01-02 to 2101-01-01
4 ssp370 2015-01-02 to 2101-01-01
5 ssp585 2015-01-02 to 2101-01-01

Note

Values of the Temporal extent column are the limits for --start-date and --end-date options with the main datatool script.

Note

The Hybrid-observation model does not accept any --scenario values, however, it covers climate date from 1950-01-01 to 2020-01-01.

Dataset Variables

The NetCDF files of the dataset contain 3 variables. You may see a list of variables by using the ncdump -h command on one of the files:

foo@bar:~$ module load gcc/9.3.0
foo@bar:~$ module load cdo/2.0.4
foo@bar:~$ ncdump -h /project/rpp-kshook/Climate_Forcing_Data/meteorological-data/ab-gov/BCC-CSM2-MR/Downscaled_BCC-CSM2-MR_MBCDS_ssp126_pr_tmn_tmx_2015.nc

Spatial Extent

The ab-gov dataset covers the entire Canadian province of Alberta (AB), in addition to northern parts of British Columbia (BC), western parts of Saskatchewan (SK), and northern parts of the American State of Montana (MT).

Short Description on ab-gov Climate Dataset Variables

This dataset only offers three climate variables: 1) daily precipitation time-series (surface level), 2) daily minimum temperature time-series (@1.5m, near-surface level), and 3) daily maximum temperature time-series (@1.5m, near-surface level). Since the frequency of this dataset is daily, and only offers precipitation and temperature values, therefore, it could be potentially used for forcing conceptual hydrological models that only need daily time-series of these variables.

The table below, summarizes the variables offered by this dataset:

Variable Name Variable (keyword for --variable) Unit IPCC Abbreviation Comments
maximum temperature tmax °C tasmax
minimum temperature tmin °C tasmin
preciptiation pr mm/day pr
