2. What is NCC?

NCC (National Centers for Environmental Prediction/National Center for Atmospheric Research Corrected by Climate Research Unit) is the near-surface meteorological data with a 6-hourly time step from 1948 to 2000 and a spatial resolution of 1x1 degre.
NCC contains the following variables:
Tair (K)Near surface air temperature at 2m
Qair (kg kg-1)Near surface specific humidity at 2m
Wind (m s-1)Near surface wind speed at 10m
S Wdown (W m-2)Surface incident shortwave radiation
L Wdown (W m-2)Surface incident longwave radiation
Psurf (Pa)Surface pressure
Rainf (kg m-2 s-1)Rainfall rate
Snowf (kg m-2 s-1)Snowfall rate

3. Data format of NCC?

The data were saved in the netCDF format.

4. Where to download NCC?

The NCC data (about 147GB) can be downloaded from http://hydro.iis.u-tokyo.ac.jp/~thanh/NCC/
Note: due to some technical reasons, the dataset for the year 1948 is no more available. We are sorry for that.
