    This study presents the results of 2 years combined field measurements of water vapor exchange with the atmosphere and simplified model calculations at Lambir Hills National Park, Sarawak, Malaysia (4 12'N, 114 02'E). The study site was located in a lowland mixed dipterocarp forest, a major type of Bornean tropical rainforest, where there is no clear seasonality in environmental factors such as radiation, temperature, vapor pressure deficits and precipitation; instead, unpredictable dry spells often occur throughout the year.

    Ten-year evapotranspiration estimates in a Bornean tropical rainforest
    (Elsevier, 2011) Tomonori Kume; Nobuaki Tanaka; Koichiro Kuraji; Hikaru Komatsu; Natsuko Yoshifuji; Taku M. Saitoh; Masakazu Suzuki; Tomo omi Kumagai
    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.
