The "Baltic Sea DIVA 4D analysis of Water_body_total_nitrogen" is the 4D gridded analysis for Dissolved total and organic nitrogen concentrations in the water column in the Baltic Sea. The analysis was performed per season using DIVA software tool (Data-Interpolating Variational Analysis). The analyses products are stored as NetCDF CF files and made available as WMS layers for easy browsing and adding. Dynamic plots obtained as a combination of WPS/WMS (Density information available by colours, time series and vertical profiles) were uploaded to 'EMODnet Chemistry Viewing and Downloading Service'. Every step of the time dimension corresponds to a 10-year average moving from 1960 to 2014. The depth dimension spans from surface to the seafloor with 21 vertical levels. The data used as input for DIVA have been extracted from the EMODnet Chemistry Download Service:
