Each of the time integrated samples taken within the model catchments contain approximately 100 subsamples automatically sampled every 90 minutes during a week. Between 20-30 weekly samples are collected from each model catchment every year during the growing season, May - November. Grab samples from the two rivers Skivarpsån and Vege å (both in the county of Skåne) are collected by hand every second week in May-June and once a month in July-November (9 samples per river per year).
The database and the data host webpages are currently only available in Swedish, but a description of how to get the data from the pesticide monitoring program and the hydrographs is described below. A translation key for the data headers and other important information is available for download here.
Guide to downloading the data:
Click the link above to get to the data host page "Jordbruksvatten" (=agricultural water). Click on the header "Växtskyddsmedel (bekämpningsmedel) i ytvatten" (=Plant protection products (pesticides) in surface water, 3rd option in the list) and then on “Analysvärden” (=analytical values) to obtain data for all areas. Alternatively, you can select one or more specific sampling locations, substances, or years from the dropdown menus (hold the Ctrl key to select more than one option from each menu). The four model catchments are: Skåne (M42), Halland (N34), Västra Götaland (O18) and Östergötland (E21) and the two rivers: Skivarpsån and Vege å in Skåne. After making your selection, click on “Analysvärden” (=analytical values) to access the download page. Enter your name (“Namn”), organization (“Organisation”), and the purpose (“Syfte”) for downloading the data. Click on “Hämta data” (=get data). This information is collected for statistical purposes to illustrate how the data is being used.
To obtain data for the daily average water discharge for the model catchment streams, go to the data host page and click on the header "Växtnäring i ytvatten" (=”Plant nutrients in surface water, 1st option in the list) and select the model catchment you are interested in (Note! There are more model catchments here than for the pesticide monitoring program because plant nutrients are analyzed in more streams). Click on “Sök” (=Search) to get to the data for the specified catchment. Check the box for the catchment and click on ”Vattenföring” (=discharge) to get to the download page. Enter your name (“Namn”), organization (“Organisation”), and the purpose (“Syfte”) for downloading the data. Click on “Hämta data” (=get data).
