这项研究正在调查加里曼丹森林泥炭地的地下水位，这有望成为更好地控制野火的指标。首先，修正Keeth-Byram干旱指数（mKBDI）计算结合基于卫星的降水GSMaP和MTSAT陆面温度（LST）。其次，分别对排水林（DF）、未排水林（UF）和排水火烧林（DB）的mKBDI与近地表地下水位（GWT）进行了回归分析。总体而言，一个模拟GWT在森林泥炭地表现出非常好的时间序列的行为沿着与原位测量。模拟的GWT对降水更敏感，导致地下水位急剧上升，更多的校准是必不可少的，以获得更好的结果。通过对中分辨率成像光谱仪（MODIS）探测到的GWT和火锅的比较，发现GWT较低的地区显然有更多的火灾发生。结果发现，mKBDI很好地校准与GWT在上述三个测量站点和泥炭火灾风险区制图在森林泥炭地一个很好的指标。这些建模结果以近乎实时的方式更新，所有数据库都在http://jica-jst.lapanrs.com/GWT/上向公众开放。
This research is investigating the ground water table at forested peatland in Kalimantan which is expected to be an indicator for better wild fire control. Firstly, modified Keeth-Byram drought index (mKBDI) was computed by incorporating satellite-based precipitation GSMaP and MTSAT land surface temperature (LST). Secondly a regression analysis was carried out between mKBDI and near surface ground water table (GWT) measurements at drained forest (DF), un-drained forest (UF) and drained burnt forest (DB) respectively. Overall a modeled GWT at forested peatland showed very good time-series of behaviors along with that of in-situ measurement. A modeled GWT was more sensitive to precipitation resulting in a drastic water table rise-up and more calibration is indispensable to get a better result. A comparison of GWT and hotpot detected by MODIS showed that lower GWT areas clearly have more fire occurrences. It was found that mKBDI was well calibrated with GWT at the above mentioned three measurements sites and a very good indicator for peat fire risk zone mapping at forested peatland. These modeling results are updated in a near-real time fashion and all the database are open to public at http://jica-jst.lapanrs.com/GWT/.
