چکیده

—Surface roughness has a significant effect on the relationship between radar hackscattcr and soil moisture. In order to use cxistinR radar satellite data for soil moisture, roughness effects must be corrected. A technique is presented that utilises Ihe data bases from soil erosion sludies and soil moisture remote sensing investigations to provide firsl order estimates «f the roughness parameters.

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...

Active microwave remote sensing for soil moisture measurement: a field evaluation using ERS-2

Active microwave remote sensing observations of backscattering, such as C-band vertically polarized synthetic aperture radar (SAR) observations from the second European remote sensing (ERS-2) satellite, have the potential to measure moisture content in a near-surface layer of soil. However, SAR backscattering observations are highly dependent on topography, soil texture, surface roughness and s...

Large-Scale Microwave Remote Sensing of Retrieving Surface Multi-parameters Using Active and Passive Satellite Data: In the Tibetan Plateau Region of Maqu

To conduct with these land surface parameters inversion using microwave observations in the bare soil surface, it is needed to estimate soil moisture (SM), surface temperature (ST) and surface roughness changes with microwave observations. High-frequency passive microwave radiometer sensitivity of the roughness is very low, traditional ground truth can’t provide an accurate large-scale roughnes...

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...

An Alternative Roughness Parameterization for Soil Moisture Retrievals from Passive Microwave Observations

The usefulness of L-band radiometer observations for the retrieval of near-surface soil moisture has already been demonstrated in many studies. Unfortunately, the ability to estimate soil moisture from these remotely sensed observations is hampered by the infeasibility to characterize the roughness of the soil surface. Given the difficulty to measure in situ soil roughness parameters, improved ...
