High-resolution tropical rain-forest canopy climate data

Canopy habitats challenge researchers with their intrinsically difficult access. The current scarcity of climatic data from forest canopies limits our understanding of the conditions and environmental variability of these diverse and dynamic habitats. We present 307 days of climate records collected between 2019 and 2020 in the tropical rainforest canopy of the Yasuní National Park, Ecuador. We monitored climate with a 10-minute temporal resolution in the middle crowns of eight canopy trees. The distance between canopy climate stations ranged from 700 m to 10 km. Apart from air temperature, relative humidity, leaf wetness, and photosynthetically active radiation (PAR), measured in each canopy climate station, global radiation, rainfall, and wind speed were measured in different subsets of them. We processed the eight data series to omit erroneous records resulting from sensor failures or lack of the solar-based power supply. In addition to the eight original data series, we present thre..., To monitor canopy climate eight canopy climate stations were established in a stratified sampling design targeting ridges (four stations) and valleys (four stations). A nearby valley and a ridge correspond to a site. Air temperature, relative humidity, photosynthetic active radiation, and leaf wetness were recorded by all canopy climate stations, while precipitation, wind, and global radiation were recorded by selected canopy climate stations.
All canopy climate stations collected data every 30 seconds and recorded data every 10 minutes between April 2019 and February 2020.
To monitor canopy climate with a high temporal resolution, we installed eight climate stations, each in the crown of a tree, using adapted climbing techniques (Perry 1978) in the second half of April 2019. These trees belonged to seven species distributed in 6 botanical families and averaged 64 + 0.6 cm (mean + SE) for DBH, 26 + 0.2 m of height, and 7.2 + 0.2 m of crown radius (Table 1); we targeted canopy trees, i.e...,
