Study On Dew Characteristics In Loess Plateau, China

In fact, in arid environment such as desert, dew plays an important role to some vegetation and ecosystem[1]. Dew can help the vegetation restore from excessive water loss state[2]. In addition, dew is an important water source for some microorganism[3], insects and small animals. In particular, the distribution of dew may influence on remotely sensed measurements[4] and remote sensing parameters such albedo[5-6]. It also effects bright temperature and the backward reflection at microwave band[7]. Therefore, remote sensing data processing is closely related to the dew variation and it is helpful to understand variation characteristics of dew to processing remote sensing data.
