CPC Global Daily Temperature

Brief Description:

  • CPC .50x.50 Global Daily Temperature

Temporal Coverage:

  • Daily 1979/01/01 to present
  • Long Term Means of daily, monthly for years 1981 to 2010.

Spatial Coverage:

  • 0.50 - degree latitude x 0.50 - degree longitude grid (720x360).
  • 89.75N-89.75SN, 0.25E-359.75E.


  • N/A

Update Schedule:

  • Updated daily

Download/Plot Data:

Variable Statistic Level Download File Create Plot/Subset
Maximum Temperature Daily Surface tmax.yyyy.nc plot
Daily Maximum Temperature Daily Long Term Mean Surface tmax.day.ltm.nc plot
Daily Minimum Temperature Daily Total Surface tmin.yyyy.nc plot
Daily Minimum Temperature Daily Long Term Mean Surface tmin.day.ltm.nc plot
Note: he daily average temperature can be generated from tmax and tmin by adding the values together and dividing by 2. You should be able to do this in any data analysis package that supports netCDF files.

Usage Restrictions:

  • None

Detailed Description:

  • This data set is used for verification by NOAA/CPC. The data is global GTS data and is gridded using the Shepard Algorithm. The values are the max/min for 6Z-6Z.


  • Real-time values change change before N days.

Related File Naming & Structure Information:

File Names:
