The derived grids are Asciigrid files for the derived variables with each pixel
representing an area about 800 (depending on latitude) by 1000 meters (30 arc seconds,

The derived grids are Asciigrid files for the derived variables with each pixel
representing an area about 800 (depending on latitude) by 1000 meters (30 arc seconds,
0.0083333333 arc degrees). We call these 1K resolution maps. The images were made using 10K data, but
to be clear, the zip files at 1K resolution. All temperatures are in tenths of degrees C.

Degree-days <0 degrees C (based on mean monthly temperature)
Degree-days >5 degrees C (based on mean monthly temperature)
Julian date of the first freezing date of autumn
Length of the frost-free period (days)
Degree-days >5 degrees C accumulating within the frost-free period
Growing season precipitation, April to September
Mean annual precipitation
Mean maximum temperature in the warmest month
Mean minimum temperature in the coldest month
Degree-days <0 degrees C (based on mean minimum monthly temperature)
Mean temperature in the coldest month
Mean temperature in the warmest month
Julian date of the last freezing date of spring
Summer precipitation: (jul+aug)
Summer precipitation balance: (jul+aug+sep)/(apr+may+jun)
Spring precipitation: (apr+may)
Winter precipitation: (nov+dec+jan+feb)
We used many additional variables that are computed from these - good examples are:
ADI Annual dryness index, DD5/MAP or sqrt(DD5)/MAP (once named AMI annual moisture index)
SMI Summer dryness index, GSDD5/GSP (once named SMI, summer moisture index)
PRATIO Ratio of summer precipitatioin to total precipitation, GSP/MAP
