DATASET
➤ netCDF format
➤ spatial: global area
➤ temporary resolution?
CMIP5 simulation data
Multi-annual averages are of interest

R-MINDED APPROACH
1) set the items’ ids to select
2) subset
3) apply a function (spacial averaging)
Classic R, ::raster, ::RCMIP5

SOLUTION
Use interpolation to regular seasonally time
instead of

SUMMARY
1) quick-and-easy solutions may be dangerous
2) careful examination of netCDF structure is essential
3) implementation to netCDF/CMIP5 packages?
Modellers have right to their own way of thinking
Practical points to be kept in mind while work with netCDF

Many thanks for your attention!
We highly acknowledge CMIP5 modelling groups and CERA-team for sharing CMIP5 simulation data. We are also very grateful to the Russian
Weather Office for supporting meteorological observation data
