The NSRDB Daily Statistics Files
The Daily Statisitcs Files (DSFs) are part of the National Solar Radiation Data Base.
A description of the files and their format
can be found in Section 3.3 of the
National Solar Radiation Data Base User's Manual.
In short, the DSFs contain the average and standard deviation of the daily total
solar energy (direct normal, diffuse horizontal, and global horizontal) for each
station-year-month and each station-year for the years 1961-1990 for all 239 stations,
where available. The 30-year averages and the standard deviations of monthly and annual
means from 1961 through 1990 are also provided. For the meteorological elements,
only monthly, annual, and 30-year averages were computed.

*Note:
These files are 54K each which may be too large to view on-line as they are. It is possible to download them directly, however, using Netscape. We do not know currently if it is
possible with other browsers, but to get them using Netscape do the following:
Macintosh
Hold down the mouse button on the link of the file which you want until an option menu pops up. Then choose the "save this link as" option and it will ask you where you want to save it.
UNIX or Windows
Click the right mouse button on the link and choose the "save this link as" option from the pop-up menu.
Some of the files are small enough to load in Netscape so you can view them on-line as well, but this downloading method will work for all of them regardless.
