OSPREy radiometers deployed at Mauna Loa Observatory August-September 2012. At the left are two instruments configured for irradiance, complete with BioShade shadowband accessory, and at the right is an OSPREy radiometer configured for radiance. The radiance instrument is mounted on a tracker and accompanied by a camera specifically used for moon tracking.
COAST 2011 used a modified UV-18A Twin Otter (from CIRPAS). Shown is the twin otter at 100 ft off the deck, flying over the science team that was deployed in a coastal research vessel in Monterey Bay. The team was tasked with obtaining "sea truth" for the aircraft overflight. The inset photo shows two of the three C-AIR instruments (BSI’s BioAIR series) onboard.

The C-OPS™ profiler, deployed by Dr. Stanford Hooker (NASA) in the Arctic as part of the Malina field campaign. The instrument is shown close to the ice edge to emphasize the ability to sample in optically complex waters, wherein a thin layer of melt water (approximately 1 m thick or less in many instances) significantly influences near-surface optical properties.
The OSPREy OR-L mounted on the solar tracker on the left, with the OR-E and BioShade shadowband in back (center) and the OR-E without BioShade to the right. At the left background is a video camera used in testing both solar trackers and solar tracking algorithms.
Summit, Greenland. Biospherical SUV-150B High Resolution Spectroradiometer in foreground with GUV behind. This is part of Biospherical's UV network and, along with Barrow, became part of NSF's Arctic Observing Network in 2009.
C-OPS Class instrument measuring light penetration under floating plastic balls in a Los Angeles Reservior.
Radiance calibration bench. Transfer radiometer seen viewing calibrated plaque illuminated by NIST-traceable FEL Standard.
ICE-Pro, a purpose-built, modified C-OPS for work under the ice, on ICESCAPE 2010. The LuZ/EdZ profiler is the red cylinder on the left. A radiometrically matching Ed0 solar reference is mounted atop the tripod, which also aids in deploying a single-channel reference sensor (QCD-2100) just beneath the ice.
Dr. Karen Frey deploys ICE-Pro, a purpose-built C-OPS for work under the ice on ICESCAPE 2010. The USCGC Healy (background) is fitted with a Biospherical Surface Ocean Reflectance System (BioSORS, S. Hooker/NASA) above-water ocean color monitor on the bow, and a Telescoping Mount for Advanced Solar Technologies (T-MAST) on the bridge, supporting the solar surface reference radiometer.
   
 


OSPREy Campaign at Mauna Loa, Hawaii

Print PDF
Biospherical Instruments recently concluded a comprehensive testing campaign of a quartet of OSPREy radiometers at NOAA’s Mauna Loa Observatory in Hawaii.  This site, at 3,396 m elevation, is the location of many long term atmospheric observations, and  its clear atmosphere makes it an ideal place for Langley-based calibrations.  Our campaign was timed to include the full moon at the end of August 2012.  This effort was funded by NASA.
 

BSI awarded another NSF grant for UV Monitoring

Biospherical’s Germar Bernhard was awarded a three year NSF grant titled “Ultraviolet Radiation in the Arctic: 2012-2015”.  This marks the 25th year that Biospherical has been monitoring UV radiation at high latitudes under NSF support.

 

BSI Presented at ASLO Meeting

Print PDF
BSI presented a poster titled, "A 1% and 1 cm Perspective Leads to a Novel CDOM Absorption Algorithm," at the 2012 ASLO Aquatic Sciences Meeting in Shiga, Japan, in July. The poster session, which is based on data obtained with BSI's C-OPS, was presented by BSI staff and one of the coauthors, Dr. Stanford Hooker, of NASA's Goddard Space Flight Center in Greenbelt, Maryland.
 

The OSPREy TM Is Here!

Print PDF
A NASA Technical Memorandum (TM) on BSI's OSPREy system is now available for download. The TM, titled Optical Sensors for Planetary Radiant Energy (OSPREy): Calibration and Validation of Current and Next-Generation NASA Missions, NASA TM# 2012—215872, was written by both NASA and BSI personnel. It is the first of two TMs explaining what OSPREy is and how it works.
 

BSI Presented at NOAA GMD Meeting

Print PDF
BSI presented a poster titled, "High Arctic Ultraviolet (UV) Radiation Levels in the Spring of 2011 Caused by Unprecedented Chemical Ozone Loss" at NOAA's Earth System Research Laboratory (ESRL), Global Monitoring Division (GMD) annual meeting this past May. Click here to see the entire agenda for the meeting, or read the part of the report titled "Ozone and UV Radiation" (Section 5c, starting on page S129) written by BSI staff, that resulted from the poster.
