Montana solar data manual

Technical Report ·
OSTI ID:5357689

Solar radiation data for Montana from 1977 to 1980 are summarized in two formats: overall monthly average and annual monthly average. Solar radiation values were all measured on a surface tilted 60/sup 0/ up from horizontal and facing due south. To convert to the expected radiation on a surface at some other tilt angle, a table of monthly tilt correction factors is provided. Cloudy day tables are included for each station. These show total cloudy days for each month for each year in the data base and the number of times each year a specified duration of cloudy days occurred. Selected long-term average climatological data from National Weather Service records were reproduced. (LEW)
