Preliminary studies and preparatory works done so far towards IOP in 1998 are as follows ;1) A disdromater which measures rain drop distribution as well as rainfall intensity was installed at Chiang Mai TMD station located in the range of Om Koi rader of BRRAA.2) Preliminary enhanced rawinsonde observations with a frequency of 4 times a day were carried out at Banhkok, Chiang Mai and Ubon Ratchathani TMD stations for 4 weeks from May to June and from August to September respectively in both 1996 and 1997.3) For non-irrigated paddy fields which are one of typical land cover types in the Chao Phraya river basin, an observational base equipped with a 10m PBL tower and a sonde releasing site was established at west Sukhothai. Sukhothai. Some preliminary studies such as operational test of AWS/GAME-PAM,comparison in durface flux estimation among Bowen Ratio, Eddy Correlation and Band-Pass Covariance methods, enhanced rawinsonde observations with a frequency of 4-8 times a day, etc.were carried out at this observational base.4) A 50m PBL tower was constructed at Kog Ma forest hydrologic experimental watershed of KU near Chiang Mai, and preliminary observations were started from the middle of February, 1997.5) Mobile observations for various types of land cover which are planned to complement the fixed flux observations were carried out around Sukhothai area.6) Development of meso-scale atmospheric model and distributed hydrologic model for the Chao Phraya river basin has been initiated.

迄今为1998年综合业务方案所作的初步研究和筹备工作如下：1）在位于BRRA Om Koi雷达范围内的清迈TMD站安装了一个测量雨滴分布和降雨强度的圆盘仪。2）在曼谷进行了初步的增强型探空仪观测，频率为每天4次，清迈和乌汶的TMD站分别于1996年和1997年5 - 6月和8 - 9月进行了为期4周的观测。在西素可泰建立了一个观测基地，配备了一个10米PBL塔和一个探空仪释放场。素可泰。在该观测基地开展了AWS/GAME-PAM的业务试验、Bowen Ratio法、Eddy Correlation法和Band-Pass Covariance法估算地表通量的比较、每天4-8次的加强探空观测等初步研究。4）在清迈附近的KU Kog Ma森林水文实验流域建造了一座50 m PBL塔，5）在素可泰地区周围进行了各种土地覆盖的移动的观测，计划补充固定通量观测。6）已经开始开发湄南河流域的中尺度大气模型和分布式水文模型。
