I have GCM global CORDEX data from 1950-2100 (Model Historical data[1951-2005] and RCP 4.5&8.5[2006-2100]) and for IMD data from [1950-2016] 1. Now I need to do extract this data for India separately model wise and then do "Delta" method bias correction and plot the time series graph to see the data before and after the bias correction. 2. The above method has to be done on daily and monthly scale separately. 3. I have precipitation data with units kg m-2 s-1 need to convert this mm/day and mm/month.

Can any one help me doing this?

dowload the downTrain function. Go to the google ant write 'dowloadTrain.m'

clear all; close all;

% For precipitation

method = [];

method.type = 'DELTA'; % or 'SCALING', 'EQM', 'AQM', 'GQM', 'GPQM',...

method.properties.CorrectionFunction = 'multiplicative';

[model_Precip,Ypred_Precip]=downTrain(ptrPrecip,ptnPrecip,method,'datesTrain',datesTrain,'datesTest',datesTest);
