Over 800 stations regularly send solar radiation data (called luminosity 
in the APRS packet specification) to APRS-IS.  In the past, it has been 
difficult to compare these data among different stations or to compare 
with data from NOAA Surface Radiation stations.  It is now easier to 
access these data, and compare them with other stations, including NOAA 
stations.  Further details and directions on how to download the data to 
a spreadsheet application are here:
