Climate Sonification

This audio is a sonification of real-time forest microclimate data recorded at 12:18 PM on April 3rd, 2025 in Alice Holt Forest, UK, as part of the Sonic Forest project. The environmental sensors measured:

Air Temperature: 18.91 °C average (18.95 °C max, 18.89 °C min)
Relative Humidity (RH): 42.45 %
Photosynthetically Active Radiation (PAR): 182.2 µmol m⁻² s⁻¹ average, total 10.93 mol m⁻²
Net Radiation (NR): 49.9 W/m² average (max 53.07, min 38.33)
CO₂ Concentration: 476.5 ppm average (max 477.4, min 475)
Wind Speed: 0.604 m/s average (max 0.75 m/s)
Battery Voltage: 13.63 V
Sonification mapping:
Pitch → controlled jointly by air temperature and CO₂ concentration.
Reverb → primarily determined by relative humidity, with additional influence from air temperature and CO₂.
Rhythmic pattern → driven by PAR levels.
Vibrato → modulated by net radiation (NR).
Background EQ → shaped by wind speed.
The result is a calm midday soundscape with bright rhythmic elements from sunlight, gentle vibrato from moderate radiation, and a tonal space shaped by temperature–CO₂ interplay.
