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...
