When deriving the precipitation data from NETCDF files of CMIP5 GCMs, should I interpolate or just get the nearest point ?

In the climate change studies, we have to use CMIP5 data sets in NETCDF files. Should we interpolate between two points when getting prcp data for a point OR get the nearest point ? What is the...

In bias correction, Quantile mapping is not improving my results?

I am trying to do bias correction for CORDEX rcm data using qmap in R. But the results are poor. The CDFs are matching and the Variance is improving. But the mean values of each months are not...

Can we use rainfall forecasting model directly ?

Many drought forecasting models use SPI values directly as the predictand ? Instead of that can we make a rainfall foresting model and then calculate the drought indices?
