WSFS-Vemala is a nutrient load and water quality model for Finnish watersheds operated by the Finnish Environment Institute (Syke). More details about the model are available here (in Finnish): https://ckan.ymparisto.fi/dataset/%7B7E6EB982-A3CA-4DE3-87C0-1B61462442DF%7D and here (in English): https://www.syke.fi/en/services/modeling/water-and-marine-modelling/vemala The model computes values for over 200 000 locations. This metadata describes a subset of the model data. The data is in CSV format and includes: 1 Date (YYYYMMDD) 2 discharge m3/s 3 TOC load 1000kg/day 4 Suspended solids load 1000kg/day 5 Total phosphorus load kg/day 6 Total nitrogen load 1000kg/day 7 Ammonium load 1000kg/day 8 Nitrate load 1000kg/day 9 Norg (organic nitrogen) load 1000kg/day 10 Phosphate load kg/day 11 Porg (organic phosphorous) load kg/day 12 PIP load kg/day The values are daily means. The dataset starts on 2000-01-01 and ends in 2025-05-26. Locations included in the dataset: tocm_21_011.dat River Vantaanjoki The coordinates in the header part of the file are in YKJ (the first set of coordinates is the discharge point) This project has received funding from the European Commission’s Horizon Europe Research and Innovation programme under grant agreement No 101094434.
