Although the native temporal resolution of the Salient Blend model is weeks, months, and quarters, Salient offers a downscaling feature to create a realistic time series from day 1 to day 365 at a daily and hourly resolution for numerous variables.
Salient uses forecast anomalies for temperature, precipitation, or winds speed to select analogs, or past years with the most similar weather conditions. Analog selection depends on the variable that is being requested. For example, we use 10m wind speed to select analogs related to wind speed.
The hourly data is selected from the historical analogs for the daily timeseries.
Hourly downscale is available for the following variables:
temp, precip, rh, wspd, wdir, wspd100, wdir100, wgst, cc, tsi, dni, dhi, snow, sm, st
