In this paper, the SOMOSTA (Soil Moisture Monitoring Station) experiment on soil moisture monitoring by Global Navigation Satellite System Reflected signals(GNSS-R) at the Valencia Anchor Station is introduced.
In this paper, the results of radiothermal remote sensing of soil moisture and temperature is presented for a test site located in Arctic tundra on the Yamal Peninsula, the Russia Federation using full-polarimetry multi-angular brightness temperature (BT) observations at the frequency of 1.4 GHz. The BT data were obtained from the Soil Moisture and Ocean Salinity (SMOS) satellite with the SMOS footprint...
The SMAP (soil moisture active passive) which is one of the satellites that specifically designed for soil moisture monitoring, was launched on 31 January 2015. Recently, the SMAP radiometer soil moisture product has been released to the public. It is very urgent to evaluate the reliability of this product before it can be widely used in hydrometeorological studies. In the study, we carried out an...
Global mapping methods of soil moisture are developed in this study using WCOM (Water Cycle Observation Mission) active/passive multichannel observations. Based on three payloads of WCOM mission with L-S bands passive observations and X/Ku active/passive observations, there are obvious advantages in soil moisture retrieval. Through evaluations of the Advanced Integral Equation Model (AIEM) simulating...
Soil moisture is a critical factor in cosmopolitan meteorological and hydrological processes. Microwave remote sensing brightness temperature is sensitive to soil moisture through the effects of moisture on the dielectric constant and hence emissivity of the soil [1]. It was found that the brightness temperature at L-band is useful for retrieving near-surface soil moisture [2–3]. The Soil Moisture...
Considering the high sensitivity of radiometer signature to soil moisture and the fine spatial resolution of radar system, the objective of this study is to evaluate the performance of soil moisture retrieval using the combination of active and passive microwave remote sensing. To achieve this objective, the quality of the SMAP (Soil Moisture Active Passive mission) L3/AP active-passive soil moisture...
FY-3B is the second satellite of FY3 (Feng Yun 3) series which was launched on November 5, 2010. One of the eleven instruments on board the FY-3B satellite is the Microwave Radiation Imager (MWRI) which is a high sensitive microwave radiometer [1]. It has 5 different frequencies from 10.65GHz to 89GHz with dual polarization. The MWRI instrument provides measurements of terrestrial, oceanic, and atmospheric...
