NRCC codes

Table 3. Element Codes
Code Var Major Description
maxt 1 Maximum temperature (°F)
mint 2 Minimum temperature (°F)
avgt 43 Average temperature (°F)
obst 3 Obs time temperature (°F)
pcpn 4 Precipitation (inches)
snow 10 Snowfall (inches)
snwd 11 Snow depth (inches)
13 Water equivalent of snow depth (inches)
7 Pan evaporation (inches)
cdd - Cooling Degree Days (default base 65)
hdd 45 Degree days below base (default base 65)
gdd 44 Degree days above base (default base 50)

These codes are used to access monthly/yearly gridded datasets directly,
not derived monthly/yearly means or sums reduced from daily gridded data.
Only available for some gridded datasets as indicated in Table 9.
