This is a nutrients product developed from CMEMS product
NORTHWESTSHELF_REANALYSIS_BIO_004_011. There are two gridded products, yearly
winter mean nitrogen concentrations, and yearly winter mean phosphate
concentrations. The data covers the period 1990 - 2014 and is at 0.111° x
0.067° resolution.
Winter means are also provided for a set of regions used for eutrophication
assessments: MSFD regions, regional seas, WFD coastal areas, and
Ecohydrodynamic regions.
Files:
ntra_winter_1990_2012.nc, ntra_winter_2013_2014.nc, phos_winter_1990_2012.nc,
phos_winter_2013_2014.nc contain gridded winter means for the years indicated.
2013 and 2014 are in separate files as the model grid changed slightly after
this point.
ntra_MSFD_winter_means_1990_2014.csv and phos_MSFD_winter_means_1990_2014.csv
contain winter nitrate and phosphate means for each of the MSFD regions:
Greater North Sea and Celtic Seas for the years 1990 - 2014.
ntra_RegionalSeas_winter_means_1990_2014.csv and
phos_RegionalSeas_winter_means_1990_2014.csv contain winter nitrate and
phosphate means for each of the regional seas (1-8, also known as charting
progress 2 regions) for the years 1990 - 2014.
ntra_WFD_coastal_winter_means_1990_2014.csv and
phos_WFD_coastal_winter_means_1990_2014.csv contain winter nitrate and
phosphate means for each of the WFD coastal assessment regions, for the years
1990 - 2014.
ntra_Ecohydro_winter_means_1990_2014.csv and
phos_Ecohydro_winter_means_1990_2014.csv contain winter means for
Ecohydrodynamic regions (cropped to the MSFD regions).
Corresponding shapefiles for all of these regions are also available
(MSFD_regions.zip, Regional_seas.zip, WFD_coastal.zip,
Ecohydrodynamic_regions_cropped.zip)
