Comparison of two retrieval methods with combined passive and active microwave remote sensing observations for soil moisture

The brightness temperature (BT) and backscattering coefficient (BSC) measured simultaneously by passive and active microwave sensors have great potential for the estimation of land surface soil moisture (SM). Several methods with combined passive and active microwave remote sensing observations for SM have been reported. Usually, the use of these methods, requires an accurate roughness conditio...

Intercomparison of Surface Roughness Parameterizations for Soil Moisture Retrieval

Soil moisture plays a key role in many hydrological and agricultural processes because it controls the water and heat energy exchange between the earth and the atmosphere. Addressing the need for routine global surface soil moisture maps, the European Space Agency (ESA) launched the Soil Moisture and Ocean Salinity (SMOS) mission in 2009. It provides L-band microwave brightness temperature obse...

Retrieval of soil surface roughness from active and passive microwave observations

Spatial and temporal variation in soil moisture plays a significant role in establishing efficient irrigation scheduling, climate change prediction, and sustainable land and water management. Passive microwave remote sensing at L-band is widely recognised as the preferred technique to measure surface soil moisture globally, with spatial resolution ranging from 40-100km. However, passive microwa...

A Change Detection Algorithm for Retrieving High-resolution Surface Soil Moisture from Smap L-band Radar and Radiometer Observations

Soil moisture is a critical hydrological variable that links the terrestrial water, energy and carbon cycles. Global and regional observations of soil moisture are needed to estimate the water and energy fluxes at the land surface, to quantify the net carbon flux in boreal landscapes, to enhance weather and climate forecast skill and to develop improved flood prediction and drought monitoring c...

Soil Moisture Retrieval from Active Spaceborne Microwave Observations: An Evaluation of Current Techniques

The importance of land surface-atmosphere interactions, principally the effects of soil moisture, on hydrological, meteorological, and ecological processes has gained widespread recognition over recent decades. Its high spatial and temporal variability however, makes soil moisture a difficult parameter to measure and monitor effectively using traditional methods. Microwave remote sensing techno...
