Download/Plot Data: (Download Issues)

Variable	Statistic	Level	Download File
Maximum Temperature	Daily	Surface	tmax.yyyy.nc
Daily Maximum Temperature	Daily Long Term Mean	Surface	tmax.day.ltm.nc
Daily Minimum Temperature	Daily Total	Surface	tmin.yyyy.nc
Daily Minimum Temperature	Daily Long Term Mean	Surface	tmin.day.ltm.nc

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.

Caveats:

Real-time values change change before N days.
