Soil moisture estimation with microwave remote sensing: a systematic review and meta-analysis

International Journal of Digital Earth
Microwave remote sensing emerged as a valuable technique for monitoring soil moisture (SM) due to the lower sensitivity to weather conditions and the ability to penetrate vegetation and surface layers.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Automated Lawn Maintenance: An Agronomic and Operational Review of Turf Health, Biodiversity, and Field Performance

Journal of Field Robotics, EarlyView.
ABSTRACT Grass mowing is one of the most resource‐consuming activities in green maintenance, whether in private areas such as home gardens or in public spaces like urban parks. In recent years, concerns related to climate change, human health, and sustainability have become increasingly prominent in green maintenance, leading manufacturers and industry

Using Airborne Laser Scanning and Sentinel‐2 to Understand Subcanopy Light Regimes and Understory Diversity of Vascular Plants in Temperate Mountain Forests

Remote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that not just Airborne Laser Scanning, but also Sentinel‐2 can effectively estimate absolute canopy cover and canopy cover heterogeneity ‐ structural metrics that determine the subcanopy light regime, found to be linked to the vascular plant species richness in the understory of temperate mountain forests.

Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

Wildlife Biology, EarlyView.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Passive microwave remote sensing for sea ice research [PDF]

Eos, Transactions American Geophysical Union, 1985
During the last decade, considerable progress has been made in the application of passive microwave remote sensing to the study of sea ice. With the December 1972 launch of the Nimbus 5 electrically scanning microwave radiometer (ESMR‐5), complete coverage of the polar regions provided the synoptic observations needed for undertaking a detailed study ...

Evaluating harvest risk with limited data: A case study on polar bears (Ursus maritimus) in East Greenland

Conservation Science and Practice, EarlyView.
We developed a state‐dependent modeling and management framework to evaluate the demographic effects of different harvest strategies on the East Greenland polar bear subpopulation. This paper is for scientists undertaking wildlife harvest risk assessments for conservation and management, and for wildlife managers responsible for establishing ...

Development of a Parameterized Model to Estimate Microwave Radiation Response Depth of Frozen Soil

Remote Sensing, 2019
The sensing depth of passive microwave remote sensing is a significant factor in quantitative frozen soil studies. In this paper, a microwave radiation response depth (MRRD) was proposed to describe the source of the main signals of passive microwave ...
