UVMONITORING

NSF UV Monitoring Support

8 June 2006 - 31 December 2008

Lead Scientist: Germar Bernhard

Observatory: NSA (North Slope of Alaska)

The NSF UV monitoring network measures solar ultraviolet radiation at six high-latitude sites and at San Diego, California. It was founded in 1987 in response to severe ozone depletion reported in Antarctica and is operated by Biospherical Instruments Inc. Instrumentation installed at network sites includes high-resolution ultraviolet-visible spectroradiometers measuring spectral irradiance between 280 and 600 nm as well as multi-channel filter radiometers. The network site at Barrow, Alaska, was established in 1991. Instrumentation is located in the Ukpeagvik Inupiat Corporation building, formerly known as Naval Arctic Research Laboratory. Until 2005, NOAA's Climate Monitoring and Diagnostics Laboratory has provided on-site operational support. Since late of 2005, on-site support is provided by ARM. Network data have been used in numerous publications and are distributed via the Internet and CD-ROMs. Preliminary data are available within one week after collection and can be accessed via the project's website at www.biospherical.com/NSF. Fully quality controlled data are published annually. The project's website also provides additional information on the network, its data and applications.
