Suspended Particulate Matter (SPM) mapping from MERIS imagery. Calibration of a regional algorithm for the Belgian coastal waters
نویسندگان
چکیده
A hydro-optical algorithm based on reflectance at 555nm has been used in the past for suspended particulate matter concentrations (SPM) retrieval from SeaWiFS over the Belgian coastal (case II) waters in Southern North Sea. The extra spectral resolution of MERIS offers the possibility of improvements, though necessitates algorithm recalibration. This study presents the calibration of the hydro-optical model used to derive SPM from MERIS reflectance for Belgian coastal waters. The model is based simply on reflectance at one suitably-chosen band. Regression analysis is carried out for seaborne measurements of reflectance and SPM taken over our region of interest, to determine and calibrate the bands best suited for SPM detection. Sensitivity of the method to errors is studied.

Meris Imagery of Belgian Coastal Waters: Mapping of Suspended Particulate Matter and Chlorophyll-a
This paper describes a first application-oriented analysis of MERIS products for Suspended Particulate Matter (SPM) and Chlorophyll-a (CHL) concentration in Belgian coastal waters. Regional algorithms designed for Belgian waters have been implemented and compared with the standard MERIS products, termed Total Suspended Matter and Algal2 respectively. The standard and regional SPM products seem ...

Abstract In the present study, sampling and analysis of size-fractionated suspended particulate matter (SPM) in coastal waters of Chabahar Bay have been done for the first time. Sampling has been conducted on December 25 of 2018 from 5 stations in different locations of the Bay in order to evaluate the effects of natural and human activities on SPM mass and composition. With an overall average...
متن کاملHyperspectral Airborne Remote Sensing of the Belgian Coastal Waters
On the 16th of June 2003 a CASI (Compact Airborne Spectrographic Imager) hyperspectral airborne remote sensing campaign took place above the Southern North Sea, just offshore of Oostende. In coincidence with the airborne overpasses seaborne measurements of water leaving reflectance and water quality parameters were performed. In addition near-simultaneous satellite imagery are available. This p...
متن کاملDevelopment of a Semi-Analytical Algorithm for the Retrieval of Suspended Particulate Matter from Remote Sensing over Clear to Very Turbid Waters
Remote sensing of suspended particulate matter, SPM, from space has long been used to assess its spatio-temporal variability in various coastal areas. The associated algorithms were generally site specific or developed over a relatively narrow range of concentration, which make them inappropriate for global applications (or at least over broad SPM range). In the frame of the GlobCoast project, ...
متن کاملVariability of the Inherent and Apparent Optical Properties in a Highly Turbid Coastal Area: Impact on the Calibration of Remote Sensing Algorithms
The Southern Bight of the North Sea is characterised by a large influence of river inputs, which results in significant eutrophication of the coastal area. High values of chlorophyll (CHL) and total suspended matter (TSM) have been reported for these waters, associated with blooms of different species and resuspension of bottom sediments. Optical properties vary considerably both seasonally and...
