Hi dear
Is this place available to predict the future period of temperature and precipitation variables (sub-basin of the watershed) based on the sixth IPCC report (SSP scenario), used SDSM and Lars - WG software for the downscaling the CMIP6 models?
Dear Parvin,
Yes, you can definitely downscale the CMIP6 GCM model outputs with free software like Statistical DownScaling Model (SDSM). SDSM is a user-friendly software package designed to implement statistical downscaling methods to produce high-resolution monthly climate information from coarse-resolution climate model (GCM) simulations. The software also uses weather generator methods to produce multiple realizations (ensembles) of synthetic daily weather sequences. SDSM can be used while impact assessments require small-scale climate scenarios, provided quality observational data and daily GCM outputs for large-scale climate variables are available.
The key inputs on daily data for both local-scale and large-scale climate variables to calibrate and validate the statistical model(s). Daily GCM outputs for large-scale variables for the future climate to drive the model(s). The current version (2.3) contains observed data libraries for use in model calibration, and GCM data for making future projections, but only for selected regions (currently Europe and Canada). Later versions will expand these databases.
The key outputs are site-specific daily scenarios for maximum and minimum temperatures, precipitation, humidity. SDSM also produces a range of statistical parameters such as variances, frequencies of extremes, spell lengths.
New users can register and download the software package at https://sdsm.org.uk/software.html
