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); Predictand; 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
