NOTICE: The station pressure at Penn State drifted by about 0.4 mb per year between 11-April-2003 and 18-June-2012. Those data have been corrected and new Penn State SURFRAD daily files have been generated with corrected pressure for the affected period.

NOTICE: The README file that describes the SURFRAD data files has been updated. Please download the latest version from any of the individual station FTP data directories, e.g., ftp://aftp.cmdl.noaa.gov/data/radiation/surfrad/Bondville_IL.
