# Irradiation
Data on irradiation are derived from the [KNMI](https://www.knmi.nl/nederland-nu/klimatologie/daggegevens). Since the location Wilhelminadorp (323) has a gap in the data (January 6<sup>th</sup> 2014 to December 15<sup>th</sup> 2017 is missing), data from the location Westdorpe (319) is used. The variable Q in the raw datafile from KNMI contains data on Global radiation [J cm<sup>-2</sup>]. The irradiation is converted into units of W d<sup>-1</sup>. The data are stored as an R-data file in the directory "/DataOS/KNMI/"
In the figure below an overview is given on the irradiation data. The figure at the top represents the data from January 1996 to February 2021 and the figure at the bottom presents the data from Janauary 2018 to February 2021.

# Bathymetry
A bathymetric map of the Oosterschelde is used to calculate the volumes and depths of the different compartments. The data are based on the ecotope map of the Oosterschelde for the year 2016 and is downloaded from the Data Management Center of Rijkswaterstaat ([DMC-share](https://www.rijkswaterstaat.nl/apps/geoservices/geodata/dmc/)). Gaps in the map are filled with available data from 2013. The map is converted to a raster with a resolution of 20m x 20m, with depths in meter relative to NAP, i.e. Dutch Ordnance Level which is approximately Mean Sea Level, and is stored as an R-data file in the directory "/DataOS/Bathymetry/"
