BSI Participated in COAST 2011

Print PDF
Three BioAIR instruments—known as the COASTal Airborne In-situ Radiometer (C-AIR) to NASA—flew onboard a modified UV-18A Twin Otter (CIRPAS) in support of the Coastal and Ocean Airborne Science Testbed (COAST) headed by a NASA/ARC team. In addition to C-AIR, a Headwall imaging spectrometer, and the AATS-14 Ames Airborne Tracking Sun-photometer simultaneously collected data over Monterey Bay during the COAST Science Mission.

NASA Highlights C-OPS and OSPREy

AOP TM Ready for Download

Print PDF

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.


New Product Announcements

  • C-PrOPS: Compact-Propulsion Option for Profiling Systems. C-PrOPS is an auxiliary technology that adds dual thruster-based dynamic positioning to the deployment package known as C-OPS. The Compact Thruster Remote Accessory (C-TRAC) is a wireless unit to control C-PrOPS.
  • 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.

  • OSPREy Systems. OSPREy instruments measure the distribution of light over the spectral range of UV-B to the near-IR, both incident on Earth's surface, and reflected from the ocean.
  • C-OPS: Compact Optical Profiling System. C-OPS instruments measure the vertical distribution of spectral radiance and irradiance in aquatic environments, as well as incident global irradiance above the water's surface.
  • New Profiler for AOPs: C-OPS. The High Resolution Multichannel Profiler is optimized for coastal remote sensing studies. C-OPS is a radiometer system for determining apparent optical properties in aquatic systems. Avoiding any influence from the shadow of the boat, the frame can be optimized for either slow descent rates for work in very shallow (e.g., 3 m) and coastal waters, or faster descent rates for observations in the open ocean.
  • AMOUR. The newly developed Advanced Multi-purpOse Usb Radiometer (AMOUR) is a high-speed USB Radiometer for research and engineering in the laboratory or field.

Profiler Ver. 3.0.1

Print PDF

Version 3.0.1 of Profiler for PRR-800 class instruments has now been released. This version incorporates commands to allow the optical channels to be "zeroed" at each of the three gain settings present in their data acquisition system. This change is made in response to suggestions from Dr. S. Hooker of NASA to be able to use these instruments in the most effective way possible, which is particularly important in working in shallow waters. Such zero corrections are normally made at the factory during calibration or recalibration, but now the user has the ability to do this in the field when the instrument is in a temperature regime similar to its field operating conditions.
