Prediction of Large-Scale Wildfires With the Canopy Stress Index Derived from Soil Moisture Active Passive

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Land surface variables such as surface soil moisture are recognized as important wildfire indicators. However, quantifying wildfire fuel combustibility through only satellite-retrieved soil moisture remains challenging, because soil moisture does not ...

Agricultural Drought Monitoring via the Assimilation of SMAP Soil Moisture Retrievals Into a Global Soil Water Balance Model

open access: yesFrontiers in Big Data, 2020
From an agricultural perspective, drought refers to an unusual deficiency of plant available water in the root-zone of the soil profile. This paper focuses on evaluating the benefit of assimilating soil moisture retrievals from the Soil Moisture Active ...

Effect of Assimilating SMAP Soil Moisture on CO2 and CH4 Fluxes through Direct Insertion in a Land Surface Model

open access: yesRemote Sensing, 2022
Soil moisture impacts the biosphere–atmosphere exchange of CO2 and CH4 and plays an important role in the terrestrial carbon cycle. A better representation of soil moisture would improve coupled carbon–water dynamics in terrestrial ecosystem models and ...

Analyzing Effects of Crops on SMAP Satellite-Based Soil Moisture Using a Rainfall–Runoff Model in the U.S. Corn Belt

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
L-band microwave satellite missions provide soil moisture information potentially useful for streamflow and, hence, flood predictions. However, these observations are also sensitive to the presence of vegetation that makes satellite soil moisture ...

Validation of SMAP Soil Moisture at Terrestrial National Ecological Observatory Network (NEON) Sites Show Potential for Soil Moisture Retrieval in Forested Areas

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Soil moisture influences forest health, fire occurrence and extent, and insect and pathogen impacts, creating a need for regular, globally extensive soil moisture measurements that can only be achieved by satellite-based sensors, such as NASA's ...

Introducing the SMAP L4 Products and Investigating the Spatio-Temporal Variability of Soil Moisture in Iran [PDF]

open access: yesNīvār, 2022
Background and objectives: Although estimation of soil surface moisture plays an important role in soil and water resources management, unfortunately, there is currently no national soil moisture monitoring network in Iran and the distribution of in situ
