Diurnal, seasonal, and altitudinal trends in microclimate across a tropical montane cloud forest

Cloud dynamics significantly influence microclimate trends in tropical montane cloud forests, with solar radiation, vapor pressure deficit, and temperature peaking earlier at higher altitudes due to seasonal shifts in cloud cover. This study analyzed diurnal, seasonal, and altitudinal patterns across a 3900-meter gradient in Manu National Park, Peru, using long-term micrometeorological data from permanent tree plots and public domain records spanning up to 17 years. Findings suggest that changes in cloud frequency and distribution, driven by climate change, could profoundly impact cloud forest ecosystems beyond the effects of rising temperatures alone.
