Stochastic Precipitation Downscaling with the RainFARM Method |
Description: |
An implementation of the RainFARM (Rainfall Filtered
Autoregressive Model) stochastic precipitation downscaling
method (Rebora et al. (2006) <doi:10.1175/JHM517.1>). Adapted
for climate downscaling according to D'Onofrio et al. (2018)
<doi:10.1175/JHM-D-13-096.1> and for complex topography as in
Terzago et al. (2018) <doi:10.5194/nhess-18-2825-2018>. The
RainFARM method is based on the extrapolation to small scales
of the Fourier spectrum of a large-scale precipitation field,
using a fixed logarithmic slope and random phases at small
scales, followed by a nonlinear transformation of the resulting
linearly correlated stochastic field. RainFARM allows to
generate ensembles of spatially downscaled precipitation fields
which conserve precipitation at large scales and whose
statistical properties are consistent with the small-scale
statistics of observed precipitation, based only on knowledge
of the large-scale precipitation field. |
