Book Ocean Color Calibration and Validation

Download or read book Ocean Color Calibration and Validation written by and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Copernicus Sentinel-3 missions, including the ongoing Sentinel-3A and -3B and the future Sentinel-3C and -3D, offer an unprecedented opportunity for long-term ocean colour observations to support global environmental and climate investigations. Nevertheless, any ocean colour mission incorporates calibration and validation activities essential for the indirect calibration of the space sensor and the validation of data products. These calibration and validation activities are largely centered on the production of highly accurate in situ reference measurements relying on state of the art measurement methods and instrumentation. Since the start of the operational ocean colour missions in 1997, the JRC sustained the required calibration and validation activities by developing unique expertise and setting up specific measurement programs and infrastructures. This expertise, measurement programs and infrastructures, currently support the Copernicus ocean colour calibration and validation tasks through the delivery and exploitation of in situ reference data essential for the quality control of satellite data products. This Technical Report aims at providing: i. a general introduction to the ocean colour paradigm; ii. an extended synopsis of requirements and strategies for satellite ocean colour missions with a detailed focus on the JRC experimental activities carried out during the last decades; and finally iii. a discussion supporting the need for a sustained support of the JRC laboratory and field measurement programs assisting the production and exploitation of in situ reference data for the validation of Sentinel-3 ocean colour products. The Report, mostly through section 2, should naturally satisfy readers interested in appraising the specific JRC activities performed to support ocean colour calibration and validation. The same Report through sections 1 and 3, should also satisfy the need for more essential information supporting the need for sustaining the JRC ocean colour validation activities currently embedded in the Copernicus Earth Observation program of major relevance for global marine and climate investigations.

Book Report for Dedicated JPSS VIIRS Ocean Color Calibration Validation Cruise

Download or read book Report for Dedicated JPSS VIIRS Ocean Color Calibration Validation Cruise written by Veronica Peterson Lance and published by . This book was released on 2015 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The purpose of this cruise aboard the NOAA Ship Nancy Foster was to collect in situ optical and ancillary data for validation of JPSS VIIRS satellite ocean color radiometry and derived products [Wang et al., 2013; Wang et al., 2014]. Specific objectives are detailed below in Section 3. The project interval was 9 to 22 November 2014. This 14-day interval included 10 days at sea (including transits), 2 staging days, 1 de-staging day and 1 day crew rest. Days at sea were 11 to 20 November 2014. Ship time aboard the NOAA Ship Nancy Foster (http://www.moc.noaa.gov/nf/) was funded through an allocation by the NOAA Office of Marine and Aviation Operations (OMAO). Ten investigator groups from 11 institutions participated in the cruise... The cruise departed from and returned to Charleston, SC, USA, the Foster's home port. The primary area of operations was the Western Atlantic along the U.S. Mid- and Southeastern Coast, including cross-shelf, Gulf Stream and blue waters"--Page 1.

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 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 Assessing the Requirements for Sustained Ocean Color Research and Operations

Download or read book Assessing the Requirements for Sustained Ocean Color Research and Operations written by National Research Council and published by National Academies Press. This book was released on 2011-12-15 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean is a fundamental component of the earth's biosphere. It covers roughly 70 percent of Earth's surface and plays a pivotal role in the cycling of life's building blocks, such as nitrogen, carbon, oxygen, and sulfur. The ocean also contributes to regulating the climate system. Most of the primary producers in the ocean comprise of microscopic plants and some bacteria; and these photosynthetic organisms (phytoplankton) form the base of the ocean's food web. Monitoring the health of the ocean and its productivity is critical to understanding and managing the ocean's essential functions and living resources. Because the ocean is so vast and difficult for humans to explore, satellite remote sensing of ocean color is currently the only way to observe and monitor the biological state of the surface ocean globally on time scales of days to decades. Ocean color measurements reveal a wealth of ecologically important characteristics including: chlorophyll concentration, the rate of phytoplankton photosynthesis, sediment transport, dispersion of pollutants, and responses of oceanic biota to long-term climate changes. Continuity of satellite ocean color data and associated climate research products are presently at significant risk for the U.S. ocean color community. Assessing Requirements for Sustained Ocean Color Research and Operations aims to identify the ocean color data needs for a broad range of end users, develop a consensus for the minimum requirements, and outline options to meet these needs on a sustained basis. The report assesses lessons learned in global ocean color remote sensing from the SeaWiFS/MODIS era to guide planning for acquisition of future global ocean color radiance data to support U.S. research and operational needs.

Although the present document represents another significant, incremental improvement in the ocean optics protocols, there are several protocols that have either been overtaken by recent technological progress, or have been otherwise identified as inadequate. Revision 4 is scheduled for completion sometime in 2003. This technical report is not meant as a substitute for scientific literature. Instead, it will provide a ready and responsive vehicle for the multitude of technical reports issued by an operational Project. The contributions are published as submitted, after only minor editing to correct obvious grammatical or clerical errors. Mueller, James L. (Editor) and Fargion, Giulietta S.
