This is a nutrients product developed from CMEMS product
NORTHWESTSHELFREANALYSISBIO004011. 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:
ntrawinter19902012.nc, ntrawinter20132014.nc, phoswinter19902012.nc,
phoswinter20132014.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.
ntraMSFDwintermeans19902014.csv and phosMSFDwintermeans19902014.csv
contain winter nitrate and phosphate means for each of the MSFD regions:
Greater North Sea and Celtic Seas for the years 1990 - 2014.
ntraRegionalSeaswintermeans19902014.csv and
phosRegionalSeaswintermeans19902014.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.
ntraWFDcoastalwintermeans19902014.csv and
phosWFDcoastalwintermeans19902014.csv contain winter nitrate and
phosphate means for each of the WFD coastal assessment regions, for the years
1990 - 2014.
ntraEcohydrowintermeans19902014.csv and
phosEcohydrowintermeans19902014.csv contain winter means for
Ecohydrodynamic regions (cropped to the MSFD regions).
Corresponding shapefiles for all of these regions are also available
(MSFDregions.zip, Regionalseas.zip, WFDcoastal.zip,
Ecohydrodynamicregions_cropped.zip)
