This dataset presents the output of the application of the Jarkus Analysis Toolbox (JAT) to the Jarkus dataset. The Jarkus dataset is one of the most elaborate coastal datasets in the world and consists of coastal profiles of the entire Dutch coast, spaced about 250-500 m apart, which have been measured yearly since 1965. Different available definitions for extracting characteristic parameters from coastal profiles were collected and implemented in the JAT. The characteristic parameters allow stakeholders (e.g. scientists, engineers and coastal managers) to study the spatial and temporal variations in parameters like dune height, dune volume, dune foot, beach width and closure depth. This dataset includes a netcdf file (on the opendap server, see data link) that contains all characteristic parameters through space and time, and a distribution plot that shows the overview of each characteristic parameters.

The Jarkus Analysis Toolbox and all scripts that were used to extract the characteristic parameters and create the distribution plots are available through Github (https://github.com/christavanijzendoorn/JAT). Example 5 that is included in the JAT provides a python script that shows how to load and work with the netcdf file.
