[!important] Not all models have the same number of scenarios, enesmble members, and variables. Each individual model needs to be investigated individually. However, ``datatool`` can ignore invalid choices automatically upon job submission. Coordinate Variables and Time-stamps ------------------------------------ Coordinate Variables ~~~~~~~~~~~~~~~~~~~~ The coordinate variables for this dataset are ``rlon`` and ``rlat`` representing the longitude and latitude points, respectively. ### Time-stamps The time-stamps are included in the original files. ``MRCC5-CMIP6`` Climate Models ------------------------------ This dataset offers downscaled 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 | Scenarios (keyword for ``--scenario``) | | | ``--model``) | | +===+========================+==========================================+ | 1 | ``CanESM5`` | ``historical``, ``ssp126``, ``ssp245``, | | | | ``ssp370``, ``ssp585`` | +---+------------------------+------------------------------------------+ | 2 | ``MPI-ESM1-2-LR`` | ``historical``, ``ssp126``, ``ssp245``, | | | | ``ssp370``, ``ssp585`` | +---+------------------------+------------------------------------------+ | 3 | ``CNRM-ESM2-1`` | ``historical``, ``ssp126``, ``ssp245``, | | | | ``ssp370`` | +---+------------------------+------------------------------------------+ ``MRCC5-CMIP6`` Climate Models’ Ensemble Members ------------------------------------------------ This dataset offers downscaled outputs of various climate models.

You may see a list of variables by browsing the dataset’s directory: .. code:: console foo@bar:~$ ls /path/to/dataset/dir/CanESM5/ssp126/r1i1p2f1/CRCM5/v1-r1/1hr/ hurs huss pr ps rlds rsds tas uas vas Spatial Extent -------------- The spatial extent of the ``MRCC5-CMIP6`` is on latitutes from ``+6.33`` to ``+82.84`` and longitudes from ``-179.99`` to ``179.99`` covering North America. The resolution is 0.11 degrees (~10km). Temporal Extent --------------- The time-stamps are already included in the original files. The dataset offers **hourly** time-series of climate variables. The following table describes the temporal extent for senarios included in this dataset: .. list-table:: :header-rows: 1 * - # - Scenarios (keyword for ``--scenario``) - Temporal extent * - 1 - ``historical`` - ``1950-01-01`` to ``2014-12-31`` * - 2 - ``ssp245`` - ``2015-01-01`` to ``2100-12-31`` * - 3 - ``ssp370`` - ``2015-01-01`` to ``2100-12-31`` * - 4 - ``ssp585`` - ``2015-01-01`` to ``2100-12-31`` * - 5 - ``ssp585`` - ``2015-01-01`` to ``2100-12-31`` .. note:: Values of the ``Temporal extent`` column are the limits for ``--start-date`` and ``--end-date`` options with the main ``datatool`` script. .. note:: ``CanESM5`` model reports all variables at the beginning of the hour ``(YYYY-mm-ddTHH:00:00)``. .. note:: ``MPI-ESM1-2-LR`` and ``CNRM-ESM2-1`` report ``pr``, ``rlds``, ``rsds`` at the middle of the hour (YYYY-mm-ddTHH:30:00), while all other variables are reported at the top of the hour.
