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).
