RainFARM.jl is a Julia library and a collection of command-line interface tools implementing the RainFARM (Rainfall Filtered Autoregressive Model) stochastic precipitation downscaling method. Adapted for climate downscaling according to (D'Onofrio et al. 2018) and with fine-scale orographic weights (Terzago et al. 2018).

RainFARM (Rebora et al. 2006) is a metagaussian stochastic downscaling procedure based on the extrapolation of the coarse-scale Fourier power spectrum of a spatio-temporal precipitation field to small scales.

Requires

julia (>=5.0), cdo (>=1.5)

Julia packages: Interpolations, ArgParse, NetCDF

Installation

You will need an implementation of the Julia language on your machine.

RainFARM is a registered package, so to install it just launch julia and from the REPL type the following:

  • in Julia >= 0.7: ] add RainFARM
  • In Julia 0.6: Pkg.add("RainFARM")
  • If you wish to try the very latest development features from this repository do: Using Pkg; Pkg.clone("https://github.com/jhardenberg/RainFARM.jl") (the using Pkgstep is only needed for Julia versions >= 0.7)

Test from the julia REPL calling using RainFARM

In the tools subdirectory (under .julia in your home) you will find the command line tools. Link or copy these to somewhere in you path in order to use them.
