2.3. Meteorological data and lake water temperature
Due to the remoteness of CHRS, there is a limited access to internet resources. Between April-August 2015, we only registered precipitation amounts (mm/day) using a tipping bucket (Oregon Scientific, USA) installed at the Base Crestones shelter. Between September 2015 and December 2017, relative humidity (%), air temperature (°C), and precipitation amounts (mm/hr) were recorded using a LW301 weather sensor kit (Oregon Scientific, USA). In January 2018, when the Internet connectivity in the shelter was improved, a Vantage Pro2 weather station (Davis Instruments, USA) was installed to register the meteorological conditions at CHRS. Between September 2015 and November 2020, the lake water temperature was recorded at 15‐min intervals by an Onset HOBO water temperature data logger installed at the west bank of Lake Ditkevi. Water temperature was also manually registered for some lake and stream water samples collected between September 2015 and December 2018 using a field portable tester (Hanna Instruments, USA).
