The relationship between ERS-2 SAR backscatter and soil moisture: generalization from a humid to semi-arid transect
نویسندگان
چکیده
A linear relationship between ERS-2 SAR backscattering coe cient (s0 ) and volumetric soil moisture was determined at both ends of a rainfall gradient in Israel. A Normalized radar Backscatter soil Moisture Index (NBMI) was derived and related strongly to soil moisture concentration. This index may allow the mapping of soil moisture conditions over large areas with C band SAR data.

The Effects of Changes in Loblolly Pine Biomass and Soil Moisture on ERS-1 SAR Backscatter
E r young (< 15 years old) lobloUy pine stands at Duke Forest (North Carolina, USA), when the ground was wet, the observed ERS-1 SAR backscatter from short-grass fields of 0.05 kg /m 2 biomass was >~ the backscatter from the stands, and there was no significant correlation between the backscatter and biomass (r 2 = 0.19). Under dry soil conditions, the backscatter increased about 2-3 dB as the ...
متن کاملSoil Moisture Measurements by Synthetic Aperture Radar and Scatterometers in the Arid and Semi-arid Environment
Water is a scarce commodity in desert regions; yet, most remote sensing experiments of soil moisture have been conducted in temperate areas. The ability to detect and reliably assess soil moisture in the arid environment has important implications both at the micro scale such as the individual farm and at the macro scale for climate modeling. A series of experiments utilizing an airborne scatte...

Soil salinization has been known as a world wide problem. It is a chemical process that causes soil degradation particularly in arid and semi-arid agriculture region. There both advantages and disadvantages of optical and microwave remote sensing in the recognition of salinization soil. In order to retrieve both soil salinity and moisture, an empirical method is presented in this paper which is...

In semiarid or arid conditions, the change of root-zone soil moisture can be almost instantaneously reflected by vegetation through biophysical process. This study investigated feasibility of mapping root-zone soil moisture using MODIS-derived NDVI via statistic approach at three sites (New Mexico, Arizona, and Texas) selected from the Soil Climate Analysis Network (SCAN). These three sites rep...
متن کاملActive 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...
