Abstract. From 2017 to 2019, an extensive sampling campaign was conducted in Belgian inland and coastal waters, aimed at providing paired data of optical biogeochemical properties support research into monitoring aquatic systems. The focused on with four lakes a lagoon during the growth season, addition samples opportunity from other lakes. Campaigns also included Scheldt estuary over tidal cycle two campaigns zone. Measured parameters include inherent (absorption, scattering beam...
This paper describes a system, named “pan-and-tilt hyperspectral radiometer system” (PANTHYR) that is designed for autonomous measurement of water reflectance. The system suitable deployment in diverse locations (including offshore platforms) the validation reflectance derived from any satellite mission with visible and/or near-infrared spectral bands (400–900 nm). Key user requirements include reliable operation at remote sites without grid power or cabled internet and only limited...
A field intercomparison was conducted at the Acqua Alta Oceanographic Tower (AAOT) in northern Adriatic Sea, from 9 to 19 July 2018 assess differences accuracy of in- and above-water radiometer measurements used for validation ocean colour products. Ten measurement systems were compared. Prior intercomparison, absolute radiometric calibration all sensors carried out using same standards methods reference laboratory. Measurements performed under clear sky conditions, relatively low sun zenith...
This paper describes a prototype network of automated in situ measurements hyperspectral water reflectance suitable for satellite validation and quality monitoring. Radiometric satellite-derived is essential to ensure that only reliable data, e.g., estimating parameters such as chlorophyll concentration, reach end-users. Analysis the differences between measurements, particularly unmasked outliers, can provide recommendations on where data processing algorithms need be improved. In massively...
Taming the beast of uncertainty has been grand project to which actuaries have dedicated much their energy and skill over at least last 50 years – roughly time since, in Hans Bühlmann's (1989) famous term, “Actuaries Second Kind” emerged.
Abstract. Because of the large diversity case 2 waters ranging from extremely absorbing to scattering and complexity light transfer due external terrestrial inputs, retrieving main biogeochemical parameters such as chlorophyll-a or suspended particulate matter concentration in these is still challenging. By providing optical for 180 sampling stations with turbidity 1 700 FNU 0.9 mg m−3 respectively, HYPERMAQ dataset will contribute a better description marine optics optically complex water...
