Air temperature (degree Celsius) has to be given for all timesteps, but longer time series is allowed. No missing values may exist. Program won’t handle them.

| + | The second to last columns are maximum air temperature for all stations or subbasins. The ID number (first row) may be ''tmaxobsid'' or ''subid''. If ''tmaxobsid'' is used, several subbasins may use the same temperature time series. ''subid'' is defined in [[start:HYPE_file_reference:GeoData.txt|GeoData.txt]]. The order of subbasins does not have to be same as in [[start:HYPE_file_reference:GeoData.txt|GeoData.txt]]. ''tmaxobsid'' may be defined in [[start:HYPE_file_reference:ForcKey.txt|ForcKey.txt]]. | ||
