Delineating soil moisture dynamics within an evapotranspiration surface barrier using spatial‐temporal analysis

An Overview of the “Triangle Method” for Estimating Surface Evapotranspiration and Soil Moisture from Satellite Imagery

An overview of the ‘triangle’ method for estimating soil surface wetness and evapotranspiration fraction from satellite imagery is presented here. The method is insensitive to initial atmospheric and surface conditions, net radiation and atmospheric correction, yet can yield accuracies comparable to other methods. We describe the method first from the standpoint of the how the triangle is obser...

Estimating Surface Soil Moisture Using Radarsat-2

Extremes in soil moisture, either too much or too little, present a significant risk to agricultural productivity. Managing and mitigating risk requires information and knowledge to assess risk potential, implement risk reduction strategies and deliver responses to this risk. Synthetic aperture radars (SARs) are sensitive to the dielectric properties of soils and are thus well suited to provide...

Estimating Soil Moisture Profile Dynamics from Near-surface Soil Moisture Measurements and Standard Meteorological Data

Evapotranspiration and Soil Moisture Dynamics in a Temperate Grassland Ecosystem in Inner Mongolia , China

Precipitation, evapotranspiration (ET), and soil moisture are the key controls for the productivity and functioning of temperate grassland ecosystems in Inner Mongolia, northern China. Quantifying the soil moisture dynamics and water balances in the grasslands is essential to sustainable grassland management under global climate change. We conducted a case study on the variability and character...
