Estimation of Soil Moisture Regime Based on Analysis of Rainfall, Air Temperature, and Landform - Soil (Case Study on River Regional Unit (SWS) Pemali - Comal)

Forum Geografi, 2004
The objectives of this research were 1) to determine soil moisture regime based on rainfall and temperature data; 2) to make a correction of the first objective based on soil moisture surplus and deficit calulation; 3) to study the pattern of soil ...

Spatial downscaling of SMAP radiometer soil moisture using radar data: Application of machine learning to the SMAPEx and SMAPVEX campaigns

Science of Remote Sensing
This study developed a random forest approach for downscaling the coarse-resolution (36 km) soil moisture measured by The National Aeronautics and Space Administration (NASA) Soil Moisture Active Passive (SMAP) mission to 1 km spatial resolution ...

Soil Moisture

, 2001
Soil moisture samples were taken at 29 sites in northwest Iowa during the last week of October 2001. Moisture samples were pulled at 1-foot increments, down to a 5-foot depth. Samples were weighed, oven dried, and reweighed at the Sutherland research farm.

MOISTURE DISTRIBUTION IN SOIL IN CONTAINERS [PDF]

Plant Physiology, 1941
In many problems dealing with the use of water by plants, containers of various sizes are adopted, in which the system is sealed against loss of moisture by evaporation from the surface, and against loss by drainage. These containers are usually weighed at intervals, and water added in measured quantities to bring about the moisture conditions desired ...

A semi-empirical model for soil moisture content retrieval based on the Kubelka-Munk model

Geoderma
Soil moisture is a critical factor influencing crop phenological development, climate patterns, and environmental changes. Accurate monitoring of soil moisture is therefore crucial for the natural ecological environment.

Validation of Satellite Soil Moisture Products by Sparsification of Ground Observations

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Dense soil moisture observation networks serve as the primary means to validate large-scale satellite soil moisture products. However, maintaining intensive observation demands substantial labor and financial resources. It is therefore crucial to address

Stochastic simulation of soil moisture dynamics in farmland in the eastern region of the Songnen Plain.

PLoS ONE
Soil moisture is the core of the hydrological cycle in agroecosystems, and most of the studies on soil moisture dynamics modeling adopt deterministic research methods, which are not well suited to study the hydrological processes in agricultural fields ...

A Preliminary Assessment of the Impact of Assimilating Satellite Soil Moisture Data Products on NCEP Global Forecast System

Advances in Meteorology, 2018
It is well documented that soil moisture has a strong impact on precipitation forecasts of numerical weather prediction models. Several microwave satellite soil moisture retrieval data products have also been available for applications.
