Hourly distribution of Relative Humidity (%; left panel) and Temperature (°C; right panel) for 2020 across three locations: MAQS (year-round), LAQS, and YoFi (the latter two from March onwards). These plots capture the seasonal variation of these key environmental parameters influencing sensor data quality.
