Downscaled data.
Using delta method, pattern scaling with ClimGen, with MarkSim, and dynamical downscaling from 1 RCM - PRECIS. |
- AR4 downscaled data
- TMAX, TMIN, MeanT, precipitation
For some methods - rainy days, solar radiation and diurnal tempertaure range are available;
|
- monthly or daily depending on method;
- PRECIS – S.American Andes; 50 km resolution
- at least 4 GCMs per SRES scenario for each method; |
- already prepared files – use a GUI to download.
- ARC-Grids, ARC-ASCII formats;
- WGS84 datum;
|
- Spatial downscaling –
Including delta method (baseline data WorldClim), pattern scaling with ClimGen – 7GCMs and A1b (1/2 degree resol, 2006-2010 period), pattern scaling with MarkSim weather generator (daily data, B1, A2, A1b, 4 GCMs, 2030s, 2050s, 2080s), dynamical downscaling PRECIS model for SAmerican Andes;
- Plots of projections by SRES emissions scenario and method
- Spatial disaggregation - based on delta method and WorldClim baseline data (about 24 models, 3 SRES emissions scenarios) at 30 arc-seconds, 2.5 arc-minutes, 5 arc-minutes, and 10 arc-minutes resolutions; monthly Tmax, Tmin, meanT, precip and bioclimatic variables;
- Useful documentation about the methods can be found here
- Tutorial to generate 19 bioclimatic variables from monthly datasets
