'''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: 

|| border=1 width=50%
|| 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 ||
|| SWdown (W m'^-2^') ||    Surface incident shortwave radiation ||
|| LWdown (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 %newwin%[[http://hydro.iis.u-tokyo.ac.jp/~thanh/NCC/ |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.

 

'''5. Refrence for the NCC data'''
