<p>The air temperature and light intensity were recorded in a tropical rainforest of Brunei Darussalam at 20-minute interval in 2017. HOBO Pendant® data loggers were attached to tree trunks approximately 2 m above ground. The obtained data can be used to study various microclimatic, biological and ecological characteristics of tropical rainforests in Brunei. The long term observations can also be used to study the impact of global climate change on the canopy of tropical rainforest.
