Soil moisture active and passive microwave products:intercomparison and evaluation over a Sahelian site
Soil moisture active passive microwave products intercomparison evaluation Sahelian site
2010/2/1
This paper presents a comparison and an evaluation of five soil moisture products based on satellite-based passive and active microwave measurements. Products are evaluated for 2005–2006 against groun...
Snow Cover of the Upper Colorado River Basin from Satellite Passive Microwave and Visual Imagery
Snow Cover Colorado River Basin Satellite Passive Microwave Visual Imagery
2009/10/27
A comparison of passive microwave images from the Nimbus-7 Scanning Multichannel
Microwave Radiometer (SMMR) and visual images from the Defense
Meteorological Satellite Program (DMSP) of the Upper C...
A Neural Network Approach to Inversion of Snow Water Equivalent from Passive Microwave Measurements
Neural Network Approach Snow Water Equivalent Passive Microwave Measurements
2009/10/26
The inversion of snow water equivalent, SWE, from passive microwave remote
sensing measurements may be accomplished by using a neural network trained
with a dense media multiple scattering model. Br...
The comparison of two models that determine the effects of a vegetation canopy on passive microwave emission
passive microwave emission vegetation canopy microwave brightness temperature
2009/5/26
Two contrasting models are used to account for the effects of vegetation on microwave emission from the soil. These are: a simple model which requires two empirically derived parameters as input data ...
Application of a coupled microwave, energy and water transfer model to relate passive microwave emission from bare soils to near-surface water content and evaporation
microwave emission near-surface water
2009/3/25
The paper examines the stability of the relation between microwave emission from the soil and the average near-surface water content in the case of relatively smooth, bare soils, and then considers th...
Using vegetation indices for soil-moisture retrievals from passive microwave radiometry
NDVI soil moisture passive microwave
2009/3/24
Surface soil moisture and the nature of the overlying vegetation both influence microwave emission from land surfaces significantly. One widely discussed but underused method for allowing for the effe...
A simple parameterisation for retrieving soil moisture from passive microwave data
passive microwave soil moisture
2009/3/23
MICRO-SWEAT, a physically based soil water and energy balance model coupled with a microwave emission model, was used to investigate the relationship between near surface soil moisture (θ0-5) and L-ba...
Application of a plane-stratified emission model to predict the effects of vegetation in passive microwave radiometry
passive microwave soil moisture vegetation
2009/3/17
This paper reports the application to vegetation canopies of a coherent model for the propagation of electromagnetic radiation through a stratified medium. The resulting multi-layer vegetation model i...
