Book The First Simbios Radiometric Intercomparison Simric 1 April September 2001

Download or read book The First Simbios Radiometric Intercomparison Simric 1 April September 2001 written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-11 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the first SIMBIOS (Sensor Intercomparison and Merger for Biological and Interdisciplinary Oceanic Studies) Radiometric Intercomparison (SIMRIC-1). The purpose of the SIMRIC-1 is to ensure a common radiometric scale of the calibration facilities that are engaged in calibrating in situ radiometers used for ocean color related research and to document the calibration procedures and protocols. SIMBIOS staff visited the seven participating laboratories for at least two days each. The SeaWiFS Transfer Radiometer SXR-II measured the calibration radiances produced in the laboratories. The measured radiances were compared with the radiances expected by the laboratories. Typically, the measured radiances were higher than the expected radiances by 0 to 2%. This level of agreement is satisfactory. Several issues were identified, where the calibration protocols need to be improved, especially the reflectance calibration of the reference plaques and the distance correction when using the irradiance standards at distances greater than the 50 cm. The responsivity of the SXR-II changed between 0.3% (channel 6) and 1.6% (channel 2) from December 2000 to December 2001. Monitoring the SXR-II with a portable light source showed a linear drift of the calibration, except for channel 1, where a 2% drop occurred in summer.Meister, Gerhard and Abel, Peter and McClain, Charles and Barnes, Robert and Fargion, Giulietta and Cooper, John and Davis, Curtiss and Korwan, Daniel and Godin, Mike and Maffione, RobertGoddard Space Flight CenterRADIOMETERS; SENSORS; OCEANOGRAPHY; REFLECTANCE; RADIANCE; SEA-VIEWING WIDE FIELD-OF-VIEW SENSOR; CALIBRATING; WATER COLOR; PROTOCOL (COMPUTERS); LIGHT SOURCES

Book Fiducial Reference Measurements for Satellite Ocean Colour

Download or read book Fiducial Reference Measurements for Satellite Ocean Colour written by Andrew Clive Banks and published by . This book was released on 2020-10-08 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean color measured by satellite-mounted optical sensors is an essential climate variable that is routinely used as a central element for assessing the health and productivity of marine ecosystems and the role of oceans in the global carbon cycle. For satellite ocean color to be reliable and used in these and other important environmental applications, the data must be trustworthy and high quality. Pre-flight and on-board calibration of satellite ocean color sensors is conducted; however, once in orbit, the data quality can only be fully assessed via independent calibration and validation activities using surface measurements. These measurements therefore need to be at least as high quality as the satellite data, which necessitates SI traceability and a full uncertainty budget. This is the basis for fiducial reference measurements (FRMs) and the FRM4SOC project, which was an European Space Agency (ESA) initiative to establish and maintain SI-traceable ground-based FRM for satellite ocean color, thus providing a fundamental contribution to the European system for monitoring the Earth (Copernicus). This Special Issue of MDPI Remote Sensing is designed to showcase this essential Earth observation work through the publication of the project's main achievements and results accompanied by other select relevant articles.

Book Proceedings Oceans From Space Venice 2010

Download or read book Proceedings Oceans From Space Venice 2010 written by and published by . This book was released on 2010 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Extended Abstracts of the poster presentations delivered at the 4th "Oceans from Space" Symposium - held in Venice, Italy, on 26-30 April 2010 - address every facet of space sciences and technologies applied to marine and maritime issues. Missions, satellites, sensors, passive and active techniques, calibration and validation schemes, algorithms and models are covered. Applications range from the study of physical dynamical processes to that of biological and ecological status, from local to global scales. The results already achieved, or soon to come, demonstrate the potential of oceanographic remote sensing to explore the dynamical and bio-geo-chemical features of the World's Oceans.
