متن کاملDevelopment of an instrument to measure density and moisture content of snow
Introduction Knowledge of snow parameters is important for climatology, meteorology, hydrology, flood prevention and hydropower industry. Liquid water in a snow pack shows a dominant effect on reflection, absorption and transmission of electromagnetic waves especially in microwave region. Liquid water in snow plays a major role in metamorphism, mechanics and hydrology of snow, and in soil engin...
متن کاملAn algorithm for generating soil moisture and snow depth maps from microwave spaceborne radiometers: HydroAlgo
A systematic and timely monitoring of land surface parameters that affect the hydrological cycle at local and global scales is of primary importance in obtaining a better understanding of geophysical processes and in managing environmental resources as well as natural disasters. Soil moisture and snow water equivalent are two quantities that play a major role in these applications. In this pape...
متن کاملSoil Moisture & Snow Properties Determination with GNSS in Alpine Environments: Challenges, Status, and Perspectives
Moisture content in the soil and snow in the alpine environment is an important factor, not only for environmentally oriented research, but also for decision making in agriculture and hazard management. Current observation techniques quantifying soil moisture or characterizing a snow pack often require dedicated instrumentation that measures either at point scale or at very large (satellite pix...
متن کاملImproving Streamflow Prediction Using Remotely-Sensed Soil Moisture and Snow Depth
The monitoring of both cold and warm season hydrologic processes in headwater watersheds is critical for accurate water resource monitoring in many alpine regions. This work presents a new method that explores the simultaneous use of remotely sensed surface soil moisture (SM) and snow depth (SD) retrievals to improve hydrological modeling in such areas. In particular, remotely sensed SM and SD ...
