An Overview of Machine-Learning Methods for Soil Moisture Estimation

open access: yesWater
Soil moisture (SM) is crucial for sustainable applications in agriculture, meteorology, and hydrology. While direct measurement provides superior accuracy, it is unfeasible when applied over extensive geographical areas because of its costly and time ...

On the spatial and temporal distribution of near surface soil moisture across a low-arctic tundra hillslope [PDF]

open access: yes, 2007
Recent changes in global climate are having an unprecedented effect on the Arctic environment. This thesis examines the surface hydrology of a heterogeneous low-Arctic Tundra heath hillslope site near Abisko, Northern Sweden (68 17'N, 18 51’E) from May

Butterfly abundances but not patch occupancy buffered by vegetation heterogeneity during climatic extremes

open access: yesEcography, EarlyView.
As extreme climatic events are becoming more frequent, we need to understand what mechanisms could buffer populations to ensure their persistence. Fragmented populations may be especially vulnerable, as exemplified by species with metapopulation dynamics whose persistence is determined by a precarious balance between frequent local extinctions and ...

Assessment of L-Band Passive Microwave Soil Moisture Retrievals Against In Situ Measurements in the North American Boreal Biome

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Climate change greatly impacts forest carbon and water dynamics in the boreal biome. To understand the vulnerability of the North American boreal biome to climate change disturbances, including droughts and temperature extremes, a biome-wide ...

Nematode survival in relation to soil moisture [PDF]

open access: yes, 1973
Established nematode populations are very persistent in the soil. It is known that they need sufficient soil moisture for movement, feeding and reproduction (fig. 5), and that there are adverse soil moisture conditions which they cannot survive.

Modeling the impacts of grazing management on livestock behavior and performance: A case study in the Peruvian Andes

open access: yesGrassland Research, EarlyView.
Our modeling study shows that livestock management strongly influences grazing behavior and animal performance in the Peruvian Andes. Furthermore, adjusting stocking rates and improving animal distribution can enhance forage intake and body condition while increasing forage biomass.

Temporal and Spatial Comparison of Agricultural Drought Indices from Moderate Resolution Satellite Soil Moisture Data over Northwest Spain

open access: yesRemote Sensing, 2017
During the last decade, a variety of agricultural drought indices have been developed using soil moisture (SM), or any of its surrogates, as the primary drought indicator. In this study, a comprehensive study of four innovative SM-based indices, the Soil

Estimation of the Spatiotemporal Variability of Surface soil Moisture Using Machine Learning Methods Integrating Satellite and Ground-based Soil Moisture and Environmental Data

open access: yesWater resources management
Monitoring and quantifying the development of drought extremes is important to agriculture, water, and land management. For this, soil moisture (SM) is an effective indicator. However, currently, real-time monitoring and forecasting of SM is challenging.

ESA CCI Soil Moisture GAPFILLED: an independent global gap-free satellite climate data record with uncertainty estimates

open access: yesEarth System Science Data
. The ESA CCI Soil Moisture multi-satellite climate data record is a widely used dataset for large-scale hydrological and climatological applications and studies. However, data gaps in the record can affect derived statistics such as long-term trends and
