The Study of Soil Moisture using Remote Sensing Data and Ground-Based Measurement: A Case Study in Phatthalung Province

Abstract

Soil moisture content was investigated in this study by 2 methods, i. e. by remote sensing data prediction and ground based measurement by self - assembled instrument. The study area covered all 11 districts in Phatthalung province, Thailand. The soil moisture content data were collected from the satellite photograph (SMAP) recorded by NASA and measurement by self - assembled instrument.  The monthly and annual average values of soil moisture content were reported. The annual average values of soil moisture content were in the range of 10 - 50 %. Their monthly average values in January to March and June to December were in the range of 20 - 50 %, no difference of these two methods was found from the result.
