Model for microwave emission of a snow-covered ground with focus on L band
a r t i c l e i n f o Keywords: Microwave radiometry L-band SMOS SMAP Radiative transfer Snow Soil freeze/thaw Passive L-band (1–2 GHz) observables are sensitive to surface soil moisture and ocean salinity, which is the core of the " soil moisture and ocean salinity " (SMOS) mission of the European Space Agency (ESA). This work investigates microwave emission processes that are important to lin...
متن کاملSalinity Effects on L-band Microwave Remote Sensing of Soil Moisture
Global satellite missions for measuring soil moisture will assume that soil salinity is unimportant for soil moisture retrieval, but many parts of the world have large areas of highly saline soil. Approximately 7% of the earth’s continental surface area is salt-affected [1], so failing to account for potential salinity-effects could compromise soil moisture satellite missions. Significant work ...
متن کاملPassive L-Band Microwave Remote Sensing of Organic Soil Surface Layers: A Tower-Based Experiment
Organic soils play a key role in global warming because they store large amount of soil carbon which might be degraded with changing soil temperatures or soil water contents. There is thus a strong need to monitor these soils and, in particular, their hydrological characteristics using, for instance, space-borne L-band brightness temperature observations. However, there are still open issues wi...
متن کاملScaling Properties of L-band Passive Microwave Soil Moisture: From SMOS to Paddock Scale
Remote sensing of soil moisture is a powerful and inexpensive way to map surface soil moisture for a range of applications, including weather prediction, water resources management and irrigation practices. Passive microwave sensors operating at L-band wavelength have shown the most potential for this task. However, this technology faces some major challenges, mostly related to correct interpre...
متن کاملL-band H Polarized Microwave Emission during the Corn Growth Cycle
L-band radiometry is recognized as a technique with a significant potential for providing spatial and temporal soil moisture variations [1, 2]. As a result, satellite missions dedicated to global soil moisture monitoring have been proposed. A 2D-interferometric L-band radiometer has recently been launched onboard the European SMOS (Soil moisture and Ocean Salinity) satellite, [3], and the NASA ...
