Snow water equivalent (SWE) is one of the key parameters for many applications in climatology, hydrology, and water resource planning and management. Satellite-based passive microwave sensors have provided global, long-term observations that are sensitive to SWE. However, the complexity of the snowpack makes modeling the microwave emission and inversion of(More)
This project proposed an embedded system for automatic mist irrigation for cardamom field, which has a wireless sensor network for real time infield sensing and control of an irrigation system. This wireless system supports the cardamom field which has both plain and slope areas. Too much watering causes diseases to cardamom. This system provides uniform(More)
in this paper. The inversion technique is based on the concept of a simple parameterized surface emission model, the Q p model, which was developed using advanced integral equation model simulations of microwave emission. Through evaluation of the relationship between roughness parameters Q p at different polarizations, it was found that they could be(More)
—Ground surface freeze–thaw cycles caused by changes in solar radiation have a great impact on soil–air water heat exchanges due to the phase transition of pore water. This influence should not be ignored in the land surface process and global environment change studies because of its large extent and the rapid changes in daily and seasonal frozen ground.(More)
— Knowledge about the surface soil water content is essential because it controls the surface water dynamics and land– atmosphere interaction. In high mountain areas in particular, soil surface water content controls infiltration and flood events. Although satellite-derived surface soil moisture data from passive microwave sensors are readily available for(More)
