ATLANTIC_CH08_Specification_5 / Map of Seasonal p90 chlorophyll-a concentration at local scale Loire-Vilaine estuary at different spatial resolutions in the past 10 years (2005-2014)
Maps of seasonal p90 (percentile 90) of Chla on the Loire-Vilaine estuary for the past ten years (2005-2014) using Atlantic West Europe Copernicus Chla L4 products (resolution of 1 km) and Kalicotier chla L3 products (resolution of 300m) druing MERIS mission (2002-20011) . For p90 averages : Method as Gohin Francis, Saulquin Bertrand, Bryere Philippe (2010) Atlas de la Température, de la concentration en Chlorophylle et de la Turbidité de surface du plateau continental français et de ses abords de l’Ouest européen. Ifremer.

- Purpose
- To produce Map (girdded layers) of Chla at a local scale of an estuary for past ten years showing a) seasonal averages of p90, b) seasonnal change in trend of Chla and c) seasonnal average of p90 at higher resolution for a perid of ten years to compare with lower resolution data (1km), to inform on data adequacy
