Current monthly degree days according to VDI 3807 for Germany, quality control not yet fully completed

The monthly degree days according to VDI 3807 are the sums of the degree days over a calendar month. The degree days refer to a room temperature of 20 degrees Celsius. Degree days are calculated as the temperature difference between room temperature and the daily mean temperature (degrees Celsius). Only the days are counted on which the daily average outside temperature is less than 15 degrees Celsius (heating day). The data in the "recent" directory are degree days calculated from current data that have not yet fully passed quality control. Monthly degree days are only calculated for those stations for which all daily mean air temperature values ​​of a month are available. The data comes from DWD stations and partner network stations that are legally and qualitatively equivalent.
