    This study was undertaken to quantify interannual variations of total evaporation (ET) in a tropical rainforest in Sarawak, Malaysia. To this end, we conducted 10-year meteorological measurements and formulated a simplified big-leaf model that reproduces transpiration (Et), rainfall interception (Ei), and ET as the sum of these.

    Vertical variation in mass and CO2 efflux of litter from the ground to the 40m high canopy in a Bornean tropical rainforest
    (Elsevier, 2021) Ayumi Katayama; Izuki Endo; Naoki Makita; Kazuho Matsumoto; Tomonori Kume; Mizue Ohashi
    Litter usually drops to the ground, but some is retained within the canopy. Mass and CO2 efflux from retained litter may play a significant role in carbon cycling in tropical rainforests where emergent trees with complicated canopy structures are observed. This study aimed to show vertical variation in the mass and CO2 efflux (Rlitter) of the retained litter and examined its contribution to carbon cycling in a Bornean tropical rainforest.
