The monthly accumulated degree days °C



a 3 dimensional array [31 watersheds, 12 months, 21 years]


  • HEC-5Q Model Output and Double Regression Temperature Modeling: Michael Wright

For watersheds with HEC-5Q modeled results, the calculation for degree days is the sum of the daily mean values for each month.

For the other regions, the calculation for degree days is the monthly mean temperature multiplied by the number of days in the month.
