Popis: The frequency of heatwave events in Europe is increasing as a result of climate change. This can have implications for the water quality and ecological functioning of aquatic systems. We deployed three spectroradiometer WISPstations at three sites in Europe (Italy, Estonia, and Lithuania/Russia) to measure chlorophyll-a at high frequency. A heatwave in July 2019 occurred with record daily maximum temperatures over 40 ◦C in parts of Europe. The effects of the resulting storm that ended the heatwave were more discernable than the heatwave itself. Following the storm, chlorophyll-a concentrations increased markedly in two of the lakes and remained high for the duration of the summer while at one site concentrations increased linearly. Heatwaves and subsequent storms appeared to play an important role in structuring the phenology of the primary producers, with wider implications for lake functioning. Chlorophyll-a peaked in early September, after which a wind event dissipated concentrations until calmer conditions returned. Synoptic coordinated high frequency monitoring needs to be advanced in Europe as part of water management policy and to improve knowledge on the implications of climate change. Lakes, as dynamic ecosystems with fast moving species-succession, provide a prism to observe the scale of future change.

We would like to thank the “Cooperativa dei Pescatori del Trasimeno” for the support in the WISPstation installation and maintenance, ARPA Umbria for useful discussions, and the Province of Perugia for the availability to use the platform in Polvese Island. Research in Estonia was also financed by Estonian Research Council grants PSG10 and PUT1598. Centre for Limnology is thanked for the opportunity to use the pier for WISPstation instal- lation and Ilmar Ansko and Martin Ligi for the instrument maintenance. We kindly acknowledge the Lithuanian Hydrometeorological Service under the Ministry of Environment for the provided meteorological data. We would like to thank the Curonian Spit National Park and Administration of Neringa municipality for the permission to install the WISPstation in Pervalka (the Curonian Lagoon, Lithuania) and Vilius Zeigis and Jonas Gintauskas for the instrument installation and maintenance. We thank Daniela Stroppiana for help with the analysis of the water spectral signatures. We thank the editor and three reviewers for their time in providing comments and suggestions that improved this manuscript.
