Copernicus Chlorophyll for the UK shelf 1998 to 2014

This is a chlorophyll product developed from CMEMS product OCEANCOLOUR_ATL_CHL_L3_REP_OBSERVATIONS_009_067: DATASET-OC-ATL-CHL-MULTI-CCI-L3-CHL_1KM_DAILY-REP-V02. There are two gridded products, yearly growing season (March-October) mean chlorophyll concentrations, and yearly growing season 90th percentile chlorophyll concentrations. The data covers the period 1998 - 2014 and is at 1km resolution.

Means and 90th percentiles are also provided for a set of regions used for eutrophication assessments: MSFD regions, regional seas, WFD coastal areas, and Ecohydrodynamic regions.

Files:

grseason_chl_mean_98_14_v2.nc and grseason_chl_90pc_98_14_v3.nc contain gridded growing season means and 90th percentiles for the years 1998 to 2014, at approximately 1km resolution.

grseason_chl_mean_98_14_v2_5km.nc and grseason_chl_90pc_98_14_v3_5km.nc contain gridded growing season means and 90th percentiles for the years 1998 to 2014, at approximately 5km resolution.

chl_MSFD_grseasonstats_1998_2014.csv contains growing season chlorophyll means and 90th percentiles for each of the MSFD regions: Greater North Sea and Celtic Seas for the years 1990 - 2014.

chl_RegionalSeas_grseasonstats_1998_2014.csv contains growing season chlorophyll means and 90th percentiles for each of the regional seas (1-8, also known as charting progress 2 regions) for the years 1990 - 2014.

chl_WFD_coastal_grseasonstats_1990_2014_v1b.csv contains growing season chlorophyll means and 90th percentiles for each of the WFD coastal assessment regions, for the years 1990 - 2014.

chl_Ecohydro_grseasonstats_1998_2014.csv contains growing season chlorophyll means and 90th percentiles for Ecohydrodynamic regions (cropped to the MSFD region extent).

Corresponding shapefiles for all of these regions are also available ( MSFD_regions.zip, Regional_seas.zip, WFD_coastal.zip, Ecohydrodynamic_regions_cropped.zip)
