FOSS4G BASED HIGH FREQUENCY AND INTEROPERABLE LAKE WATER-QUALITY MONITORING SYSTEM

In Switzerland, lake monitoring is done by cantons and lake commissions and therefore heterogeneous and often not public. Here, we present a publicly available dataset of physical lake monitoring data of 21 Swiss lakes, including metadata and derived variables. We used the data to compare the evolution of Swiss lakes and we found that temperature, heat content and stratification strength have strongly increased. In contrast, deepwater oxygen do not show clear trends during the last few decades.
