Biospherical Instruments has just released the GUVis-3511, the latest member of BSI's line of atmospheric radiometers. The GUVis-3511 is based on BSI’s proprietary microradiometer technology and available with up to 19 channels, ranging from 305 to 1,640 nm.  The instrument can also be equipped with a shadowband accessory to determine the direct solar irradiance. Depending on configuration, the GUVis-3511 affords the measurement of the UV Index and the retrieval of aerosol optical depth, cloud optical thickness, and total column ozone.

The 2013 issue of the "NOAA Arctic Report Card" was released today at a press conference during the meeting of the American Geophysical Union in San Francisco. BSI senior scientist Dr. Germar Bernhard is the lead author of two essays on ozone and UV radiation that are part of this report. The Report Card is available here.

A paper by BSI senior scientist Dr. Germar Bernhard and seven co-authors titled "High levels of ultraviolet radiation observed by ground-based instruments below the 2011 Arctic ozone hole" has been published by Atmospheric Chemistry and Physics. Measurements at 13 Arctic and Scandinavian locations performed in 2011 are compared with historical data. Observations of UV spectroradiometers operated by BSI as part of NSF's Arctic Monitoring Network contributed to this study. The paper is available here.

BSI senior scientist Dr. Germar Bernhard was invited to become a co-author for the 2014 assessment on Environmental Effects of Ozone Depletion and its Interactions with Climate Change to be published by the United Nations Environment Programme (UNEP). More details on this activity are available here

Biospherical Instruments will be exhibiting at the OCEANS 2013 MTS/IEEE Conference in San Diego, CA, September 23-26, 2013. The conference is at the Town and Country Resort and Conference Center. Come visit us at Booth #236 in the Grand Exhibit Hall.

Both C-OPS and OSPREy are highlighted in NASA’s Ocean Ecology Science Research Portal in the Instrument Development section. (Click here on C-OPS or OSPREy to be taken directly to the instruments' respective Portal page.)

The NASA Technical Memorandum written by Biospherical and NASA titled, "Advances in Measuring the Apparent Optical Properties (AOPs) of Optically Complex Waters,” NASA TM-2010-215856, is now available for download. This TM documents the Biospherical systems that support both in-air and in-water AOP determinations and describes the development of the Microradiometer and C-OPS, as well as the SHALLO family of instruments. For your convenience, PDFs of individual chapters from this TM have been included on our Web pages that deal with their respective instruments.

In February 2010, an article titled "Climatology of Ultraviolet Radiation at High Latitudes Derived from Measurements of the National Science Foundation’s Ultraviolet Spectral Irradiance Monitoring Network" was published in the book UV Radiation in Global Climate Change: Measurements, Modeling and Effects on Ecosystems. The book was edited by W. Gao, D.L. Schmoldt, and J.R. Slusser, and is available from Tsinghua University Press, Beijing, and Springer, New York (ISBN 978-3-642-03312-4).

20 October 2009: Data from the UV Monitoring Network were accepted for submission to the data center of the Network for the Detection of Atmospheric Composition Change (NDACC). According to the acceptance letter, the decision was based on BSI's demonstrated expertise in spectral UV irradiance measurements, and the value of the existing database. The reviewers acknowledged that the data from these instruments are close to NDACC specifications, that the instruments are situated at key geographic locations, and there already is a hugely valuable time series of data available from them.
