ASD | Soil moisture content estimate with drying process segmentation using shortwave infrared bands
Soil moisture content estimate with drying process segmentation using shortwave infrared bandsSoil moisture is an essential factor directly impacting a variety of environmental processes, including evaporation, infiltration, and runoff, etc. Moreover, soil moisture also plays an important role in related fields of studies, such as evapotranspiration and food security for agriculture, wetland degradation for ecosystem balance, drought for climate change, and even energy exchange between land-atmosphere interface.Ground-based measurements can provide data that are easily calibrated and acquired continuously over an extended time. However, each measurement is only targeting a single, small area, making it difficult to support spatial variation studies, or field studies. Microwave remote sensing is widely used for soil moisture monitoring over large spatial scales, based on the large contrast between the dielectric properties of water and soil. But it is not suitable for various researches...
