“…Not only does lake evaporation play a fundamental role in these budgets through the physical removal of fresh water, but the cooling effect of latent heat flux is also central to the modification of lake temperature, and related processes such as stratification (Mishra et al, 2011;Lenters et al, 2013;Spence et al, 2013;Van Cleave et al, 2014) and vertical mixing (MacIntyre et al, 2009;Ye et al, 2019), with likely impacts on lake chemistry and biota (Likens et al, 2009;Williamson et al, 2009;Wahed et al, 2014). Importantly, lake evaporation also contributes to critical feedbacks within lakes, including interactions between evaporation and lake surface temperature (Lenters et al, 2013;Spence et al, 2013;Van Cleave et al, 2014;Ye et al, 2019;Kishcha et al, 2021), feedbacks between salinity and evaporation rates (Shilo et al, 2015;Riveros-Iregui et al, 2017), and the coupling of evaporation with changes in lake level and extent (Marsh and Bigras, 1988;Li et al, 2013;Friedrich et al, 2018;Zhan et al, 2019). While evaporation substantially influences various processes within the lake, fluctuations in water level represent, arguably, one of the most important ones for the ecosystem services that lakes provide.…”

“…Satellite images are an important tool in the case of research on water ecosystems, and find application in reference to many issues concerning both biotic [64][65][66] and abiotic processes [67][68][69]. A number of papers refer to the elementary feature, namely water temperature, and the applied methods analyze the issue at various temporal and spatial scales [15,[70][71][72][73][74]. As mentioned in the introduction to this paper, research on lake water temperature in Poland with the application of satellite images has found no broader application to date, as confirmed by scarce papers in the scope.…”

Changes in lake water temperature, observed with the greatest intensity during the last two decades, may significantly affect the functioning of these unique ecosystems. Currently, in situ studies in Poland are conducted only for 38 lakes using the single-point method. The aim of this study was to develop a method for remote sensing monitoring of lake water temperature in a spatio-temporal context based on Landsat 8 imagery. For this purpose, using data obtained for 28 lakes from the period 2013–2020, linear regression (LM) and random forest (RF) models were developed to estimate surface water temperature. In addition, analysis of Landsat Level-2 Surface Temperature Science Product (LST-L2) data provided by United States Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA) was performed. The remaining 10 lakes not previously used in the model development stage were used to validate model performance. The results showed that the most accurate estimation is possible using the RF method for which RMSE = 1.83 °C and R2 = 0.89, while RMSE = 3.68 °C and R2 = 0.8 for the LST-L2 method. We found that LST-L2 contains a systematic error in the coastal zone, which can be corrected and eventually improve the quality of estimation. The satellite-based method makes it possible to determine water temperature for all lakes in Poland at different times and to understand the influence of climatic factors affecting temperature at the regional scale. On the other hand, spatial presentation of thermics within individual lakes enables understanding the influence of local factors and morphometric conditions.

“…): its surface area is ~166 km 2 and the maximal depth is ~40 m. Atmospheric low-pressure systems, known as Cyprus Lows, are the main cause of rainfall of ~400 mm per year over Lake Kinneret during the rainy season [23]; these low-pressure systems are also instrumental in the cooling of surface and subsurface water in the lake, according to Kishcha et al [24]. Satellite MODIS data on Kinneret SWT during the last two decades (measured in the skin layer of 10-20 microns) revealed the absence of SWT trends in the summer months despite the presence of increasing atmospheric warming: this was explained by the influence of increasing evaporation on Kinneret SWT [25]. Desert dust intrusions are accompanied by deposition of dust particles, in accordance with Kishcha et al [26].…”

The role of dust intrusions in the formation of lake heatwaves has not yet been discussed in previous publications. We investigated a lake heatwave (LHW) and an atmospheric heatwave (AHW) in the freshwater Lake Kinneret in the Eastern Mediterranean: these were caused by an extreme dust intrusion that lasted for a 10-day period (7–17 September 2015). The AHW and LHW were defined as periods of abnormally high air temperature (Tair) and lake surface water temperature (SWT) compared to their 90th percentile thresholds in September. In the daytime, the maximal intensities of AHW and LHW reached 3 °C and 2 °C, respectively. This was despite the pronounced drop in solar radiation due to the dust radiative effect. The satellite SWT retrievals were incapable of representing the abnormally high SWT in the presence of the extreme dust intrusion. Both METEOSAT and MODIS-Terra showed a sharp decrease in the SWT compared to the actual SWT: up to 10 °C in the daytime and up to 15 °C in the nighttime. Such a significant underestimation of the actual SWT in the presence of a dust intrusion should be considered when using satellite data to analyze heatwaves. In the absence of moisture advection, the AHW and LHW were accompanied by an increase of up to 30% in absolute humidity (ρv) over the lake. Being a powerful greenhouse gas, water vapor (characterized by an increased ρv) absorbed most of both the upwelling and downwelling longwave thermal radiation, heating the near-ground atmospheric layer (which is in direct contact with the lake water surface), in the daytime and nighttime. In the nighttime, the maximal intensity of the AHW and LHW reached 4 °C and 3 °C, respectively. Because of the observed steadily increasing dust pollution over the Eastern Mediterranean during the past several decades, we anticipate that dust-related lake heatwaves will intensify adverse effects on aquatic ecosystems such as reducing fishery resources and increasing harmful cyanobacteria blooms.
