Dissolved inorganic nitrogen (DIN) and particulate organic nitrogen (PON) are expressed in mmol-N m<sup>-3</sup> by dividing by the molecular weight of nitrogen (14 g mole-1) and multiplying by 1000 (l m<sup>-3</sup>).
Additionally, NIOZ measured nutrients (NO3 and particulate organic nitrogen) and chlorophyll-a at 8 locations ((NIOZ_1 to NIOZ_8)) in the Oosterschelde from 1995 to 2013. The data are combined with the data from Rijkswaterstaat. Finally, negative values for PON are set to 0 and for the stations in the Oosterschelde, the concentration of particulate organic nitrogen is set to a maximum of 30 mmol-N m<sup>-3</sup>.
The data are stored as R data file (*.rds) in the subdrirectory “./DataOS/WQData/”.

The concentrations of WALCRN2 and STEENBGN are used for the boundary concentrations at the North Sea and Krammersluizen, respectively (function “Boundary_NPZ()”). For the location WALCRN2 data of PON is only available from the webserver until December 31<sup>st</sup> 2018. The data in the Oosterschelde is used to compare the model results with the observation with the visualization app.

# Water Temperature
Data on water temperature in the Oosterschelde is derived from [Rijkswaterstaat](https://waterinfo.rws.nl). The location "Marollegat", situated in the eastern part of the Oosterschelde (slightly east from location NIOZ_8) is selected since a relative complete timeserie is available for this location from January 1<sup>st</sup> 2000. From the data, daily averaged water temperature is calculated. For the days with missing data, the averaged data from NIOZ is used.
