Circumsolar Radiation Data: The Lawrence Berkeley Laboratory Reduced Data Base


The Lawrence Berkeley Laboratory Reduced Data Base contains about 200 megabytes of information, including detailed intensity profiles of the solar and circumsolar region, the total and spectrally divided direct normal radiation data, as well as the total hemispherical solar radiation in the horizontal plane and the plane facing the sun.

Data are available for 11 locations in the United States in the period 1976 to 1981. The measurements were made by four circumsolar telescopes operating about 16 hours per day. The Reduced Data Base represents about one-tenth of the total data taken by the circumsolar telescopes.


Data Files*

  File size in megabytes follows View.


*Note:

Some of these files are 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.
