Open Source - Yes

Downscaling on the fly using analogs and linear regression, so far.

- Downscaled on the fly GCM data
- Results from downscaling method validation

- Tmax, Tmin, total daily precip

- stations or gridded data at required resolution

- Daily

- Main focus on Europe; potentially can downscale rest of the world

- Station and gridded data

- A1b, A2, B1

- BCM2, CNCM3, HadGem2, ECHAM5

Predictor fields -
dataset ERA 40 Reanalysis or NCEP/NCAR Reanalysis, period, region, variable, level, time (00z or 12Z);
Downscaling method;
Downscale – choose scenario, model and decade.

Output – time series in a csv format

- Downscaling on the fly
- Extensive validation section which includes results from cross-validation on the 25% of the available data – validation on a daily scale or 10-day aggregated scale – IQR, percentiles, variance, median, max, min and mean values; metrics of “accuracy” (Correl. coeff, MAE, RMSE, etc.) and “reliability” (Bias KS p-score, PDF score, etc.)

- Allows for ensemble approach
-Downscaling performed separately for each experiment and by decade
- User can upload proprietary dataset
