Assessing the Accuracy of PRISMA Standard Reflectance Products in Globally Distributed Aquatic Sites
Abstract PRISMA is the Italian Space Agency’s first proof-of-concept hyperspectral mission launched in March 2019. The present work aims to evaluate the accuracy of PRISMA’s standard Level 2d (L2d) products in visible and near-infrared (NIR) spectral regions over water bodies. For this assessment, an analytical…
Evaluation of Earth Observations and In Situ Data Assimilation for Seasonal Hydrological Forecasting
Abstract Earth observations (EOs) are a valuable complement to in situ measurements in hydrology because they provide information in locations where direct measurements are unavailable or prohibitively expensive to make. Recent advances have enabled the assimilation of data sets of different physical variables into hydrological…
Evaluation of PRISMA hyperspectral data for inland and coastal water applications
Abstract This study aims to evaluate the consistency of remote sensing reflectance (Rrs) derived from PRISMA hyperspectral sensor in inland and coastal waters. The accuracy of PRISMA Level 2D errs products as distributed by Italian Space Agency and Rrs obtained from other atmospheric correction tools…
Assessment of PRISMA water reflectance using autonomous hyperspectral radiometry
Abstract Hyperspectral remote sensing reflectance (Rrs) derived from PRISMA in the visible and infrared range was evaluated for two inland and coastal water sites using above-water in situ reflectance measurements from autonomous hyper- and multispectral radiometer systems. We compared the Level 2D (L2D) surface reflectance, a standard product distributed by…
Evaluation of PRISMA and DESIS data for water quality mapping: a focus on PrimeWater project study areas
Abstract This study presents an overview of the potentialities of PRISMA and DESIS hyperspectral sensors with a focus on PrimeWater project basins [2]. Firstly, Level 2 (L2) products, provided by the automatic processors of PRISMA (constantly being updated) and DESIS, were evaluated in terms of…
The impact of assimilating Earth Observation and in-situ data on seasonal hydrological predictions
Abstract Earth Observations (EO) have become popular in hydrology because they provide valuable information in locations where direct measurements are either unavailable or prohibitively expensive to make. Recent scientific advances have enabled the assimilation of EO’s into hydrological models to improve the estimation of initial…
