[!important] Not all models have the same number of scenarios, enesmble members, and variables. Each individual model needs to be investigate individually. [!caution] Currently, ``datatool`` is NOT capable of identifying various versions of dataset files. In this dataset, as can be observed files for ``v1.1`` (those indicated with a ``_v1.1_`` in their file names) are ignored. This will be addressed in the future versions. ``nex-gddp-cmip6`` Climate Models --------------------------------- This dataset offers downscaled outputs of various climate models.

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: .. list-table:: :header-rows: 1 * - # - Scenarios (keyword for ``--scenario``) - Temporal extent * - 1 - ``historical`` - ``1950-01-01`` to ``2014-12-31`` * - 2 - ``ssp126`` - ``2015-01-01`` to ``2100-12-31`` * - 3 - ``ssp245`` - ``2015-01-01`` to ``2100-12-31`` * - 4 - ``ssp370`` - ``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. Dataset Variables ----------------- The NetCDF files of the dataset contain various variables. You may see a list of variables by browsing the dataset’s directory: .. code:: console foo@bar:~$ ls /project/rrg-mclark/data/meteorological-data/nasa-nex-gddp-cmip6/NEX-GDDP-CMIP6/ACCESS-CM2/ssp126/r1i1p1f1/ hurs huss pr rlds rsds sfcWind tas tasmax tasmin Spatial Extent -------------- The ``nex-gddp-cmip6`` dataset spatial extent is global. Short Description on ``nex-gddp-cmip6`` Climate Dataset Variables ----------------------------------------------------------------- This dataset offers 9 climate variables: 1) precipitation, 2) mean air temperature, 3) daily maximum temperature, 4) daily minimum temperature, 5) specific humidity, 6) relative humidity, 7) shortwave radiation, 8) longwave radiation, and 9) wind speed. Since the frequency of this dataset is daily, including daily time-series of precipitation and air temperature, it could be potentially used for forcing conceptual hydrological models that only need daily time-series of these variables. Furthermore, with common existing disaggregation methods existing in the literature, one can generate sub-daily time-series of each variable and use them for forcing physically based models that may need more climate variables as their forcing data. The table below, summarizes the variables offered by this dataset: .. list-table:: :header-rows: 1 * - Variable Name - Variable (keyword for ``--variable``) - Unit - IPCC Abbreviation - Comments * - maximum temperature@2m - ``tasmax`` - K - tasmax - near-surface 2m level * - minimum temperature@2m - ``tasmin`` - K - tasmin - near-surface 2m level * - precipitation - ``pr`` - mm/day - pr - surface level * - relative humidity - ``hurs`` - % - hurs - near-surface level * - specific humidity - ``huss`` - 1 - huss - near-surface 2m level * - longwave radiation - ``rlds`` - W/m^2 - rlds - surface level * - shortwave radiation - ``rsds`` - W/m^2 - rsds - surface level * - wind speed@10m - ``sfcWind`` - m/s - (N/A) - near-surface 10m level * - mean air temperature@2m - ``tas`` - K - tas - near-surface 2m level For the most up-to-date information please visit `NASA’s NEX-GDDP-CMIP6 project website `__.
