For each RST observation, the corresponding value of the environmental variable was found by using the observed value (if available) or the interpolated value formed by neighboring observations (“Data integration and interpolation” section). These plots illustrate the LOESS curves (black line) fit to the entire environmental data for radiation, temperature (separately for each location), CO2, and O2. A linear interpolation was used for noise (separately for daytime and nighttime). Each hollow blue circle corresponds to the observed hourly average (CO2, O2, temperature) or daily average (noise, radiation) that was used for an RST observation; the green diamond indicates that the interpolated value was used.
