Environmental factors influencing detection of ring‐necked pheasant broods during August roadside surveys

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 3, April 2026.
We evaluated the influence of environmental factors on detection probability of ring‐necked pheasant broods surveyed during roadside surveys across 11 states. Wind speed, cloud cover, morning dew conditions, and soil moisture influenced detection probabilities and should be the focus of methodological or statistical control in future landscape‐scale ...

Determinación de la evapotranspiración con datos satelitales y de reanálisis utilizando Google Earth Engine

open access: yesTecnología y ciencias del agua
Los flujos verticales, dentro del ciclo hidrológico, son una de las variables de mayor relevancia en zona de llanura, dado que las pendientes varían entre 0 y 5%, y los flujos horizontales no son significativos.

SMAP and CalCOFI Observe Freshening during the 2014–2016 Northeast Pacific Warm Anomaly

open access: yesRemote Sensing, 2018
Data from NASA’s Soil Moisture Active Passive Mission (SMAP) and from the California Cooperative Oceanic Fisheries Investigations (CalCOFI) were used to examine the freshening that occurred during 2015⁻2016 in the Southern California Current ...

Tendencies of Soil Microbial NO Emissions During HI‐SCALE as Predicted by a Nitrification/Denitrification Scheme

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Many atmospheric chemical processes, including the formation of secondary organic aerosol (SOA), are strongly modulated by the reactions of NO and NO2NOx ${\text{NO}}_{2}\ \left({\text{NO}}_{x}\right)$. Though NOx ${\text{NO}}_{x}$ is controlled by anthropogenic emissions near urban areas, in rural areas soil microbes can be a significant ...

The Socio-genetic marginalization in Asia programme (SMAP) [PDF]

open access: yes, 2005
SMAP, the Socio-genetic Marginalization in Asia Programme, which started off in August 2004, is a research programme set up with the support of the Netherlands Science Organisation (NWO), IIAS, and the Amsterdam School for Social Science Research (ASSR).

Modeling soil moisture from rainfall: An evaluation of the diagnostic soil moisture equation

open access: yesVadose Zone Journal, Volume 25, Issue 2, March/April 2026.
Abstract The diagnostic soil moisture equation (DSME), which estimates soil moisture from antecedent precipitation, can be used to gap‐fill and extend existing in situ records. We train and evaluate the DSME at 157 Soil Climate Analysis Network and 113 US Climate Reference Network (USCRN) stations across the contiguous United States.

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 ...

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,
