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.

16 July 2009: NSF awards a grant to the University of Chicago and Biospherical Instruments to perform ultraviolet radiation measurements in the Arctic. As part of the project, the former sites of the NSF UV Monitoring Network become part of the Arctic Observing Network. The key intellectual merit of the project centers on acquiring data that can be used to advance knowledge (1) of the present and future solar radiation climate of the Arctic, and (2) of the factors that drive changes in the UVR. For example, by combining UV data with other measurements and modeling, parameterizations can be developed to predict future UV intensities and improve climate models (e.g., CCMs). The project is overseen by the University of Chicago. BSI will be a subcontractor to UC and will be responsible for operating the instruments and producing quality-controlled data products.

In October 2008, Biospherical Instruments embarked on a joint project with NASA to develop and deploy a state-of-the-art above-water radiometer system in support of current and next-generation ocean color satellite missions. The system is called Optical Sensors for Planetary Radiant Energy (OSPREy), and will provide high-quality measurements of the sea, Sun, sky, and Moon. The measurements will satisfy the accuracy requirements for the vicarious calibration and algorithm validation of ocean color satellites.
In January 2005, BSI received a Small Business Innovative Research (SBIR) Phase I award from NASA to develop microradiometers. The project was completed successfully and a Phase II award was granted. Microradiometers are now the heart of BSI's latest line of radiometers.
