This study examines the relationship between atmospheric parameters—air
humidity, air pressure, and surface temperature—at two measurement sites near the
Great Taevaskoda sandstone cliff in southern Estonia. Measurements were taken at
a clearing (lagendik) and a forested area (metsaalune) at different elevations (40.5 m
and 68.5 m above sea level, respectively). Instruments included a barometer for air
pressure, a psychrometer for humidity, and an infrared thermometer for surface
temperature. Results showed that air humidity decreased by 11.2% and air pressure
by 3 hPa with elevation, while surface temperature was 5.5°C lower in the forest.
The study confirmed that temperature under tree cover is lower, humidity is higher
near rivers, and pressure varies with elevation. Further research could involve more
precise measurements, simultaneous data collection, and integrating biospheric and
pedospheric data to explore vegetation and soil effects on atmospheric conditions.
