how to select predictors for statistical downscale? Because the downscale output did not give peak values and zero values as in the Predictand Series. Please anyone knows this I need a kind help to solve this for my research
1. First select the study domain over which the predictor data shows highest spatial correlation with predictand.
2. Forward and backward multiple regression between observational data and potential predictors using 6-7 leading EOF of predictors. Check the p-value for individual predictors.
3. To validate the results downscale the predictand using best predictor and compare the downscaled signal as well as correlation (Scatter plot) with predictand.
