  <dc:description xmlns:dc="http://purl.org/dc/elements/1.1/">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*)</dc:description>
