DAYSIM Header File Keyword: wea_data_file

Irradiance input data file input for ds_shortterm. The required file format can have a six row header (see below) followed by multiple rows of the form: month day hour direct diffuse. Hour is a floating variable between 0 and 24 and corresponds to the middle of the time interval that the row represents. During the day, vanishing global irradiances are not allowed. Missing data rows at night are ignored.
