Abstract
This dataset contains gridded coastal zone water colour data for the local region around the United Kingdom with a spatial resolution of 100m, derived from the Multispectral Instrument (MSI) on the Sentinel 2A and 2B satellites. These data allow monitoring of coastal waters in finer detail and observations in estuaries, bays and lagoons. It was produced within the Earth Observation Climate Inforemation Service (EOCIS) project as one of their high resolution UK (CHUK) datasets.
Data are provided on the British National Grid, and 3 products are available: a netCDF product which containing all derived variables; and additionally two geotiff products containing chlorophyll-a concentration and Total Suspended Matter (TSM) respectively.
This dataset will be extended in the future via an NEODAAS (NERC Earth Observation Data Analysis and Artificial-Intelligence Service) activity.
