It consists of two vertically-integrated steady-state advection\nequations describing: (i) the cloud water density and (ii) the hydrometeor\ndensity. Solving these equations using Fourier transform techniques,\nderives a single formula relating terrain and precipitation.\n\nPlease refer to the original manuscript of `Smith \u0026 Barstad (2004)`_ to understand\nthe model physics and limitations.\n\nInstallation\n------------\n\nRequired dependencies:\n\n* Python 3.9 or later\n* `numpy`_\n\nOptional dependencies (required for fastscape extension):\n\n* `fastscape`_\n* `xarray-simlab`_\n\n.. _`numpy`: https://numpy.org\n.. _`fastscape`: https://github.com/fastscape-lem/fastscape\n.. _`xarray-simlab`: https://github.com/benbovy/xarray-simlab\n\nTo install the package simply go to terminal and use pip to install the latest version from our GitHub repository:\n\n.. code:: shell\n\n    pip install git+https://github.com/fastscape-lem/orographic-precipitation.git\n\nUsage\n-----\nSome examples are shown in the `notebooks`_ folder (Jupyter Notebooks).\n\n.. _`notebooks`: https://github.com/fastscape-lem/orographic-precipitation/tree/master/orographic_precipitation/notebooks\n\nAcknowledgement\n---------------\n\nThis project is supported by the `Earth Surface Process Modelling`_ group of\nthe German Research Centre for Geosciences in Potsdam, Germany.\n\n.. _`Earth Surface Process Modelling`: http://www.gfz-potsdam.de/en/section/earth-surface-process-modelling/\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffastscape-lem%2Forographic-precipitation","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffastscape-lem%2Forographic-precipitation","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffastscape-lem%2Forographic-precipitation/lists"}
