Validation of Landsat land surface temperature product in the conterminous United States using in situ measurements from SURFRAD, ARM, and NDBC sites

International Journal of Digital Earth, 2021
Since 1982, Landsat series of satellite sensors continuously acquired thermal infrared images of the Earth’s land surface. In this study, Landsat 5, 7, and 8 land surface temperature (LST) products in the conterminous United States from 2009 to 2019 were

Evapotranspiration Estimation and Irrigation Performance Assessment Using Remote Sensing: A Case Study of the Ergani Dam Irrigation System (Turkey)

Irrigation and Drainage, EarlyView.
ABSTRACT Efficient water resource management is critical for sustainable agriculture, with evapotranspiration (ET) serving as a key parameter. Remote sensing (RS) techniques offer cost‐effective approaches for ET estimation and irrigation performance assessment in extensive agricultural systems.

Aplicação do algoritmo S-SEBI na obtenção da evapotranspiração diária em condições áridas Application of the S-SEBI algorithm to obtain the daily evapotranspiration in arid conditions

Revista Brasileira de Meteorologia, 2010
O principal objetivo desse estudo foi determinar a evapotranspiração real diária (ETr) da vegetação tamarisk através de técnicas micrometeorológicas e de sensoriamento remoto, e validar os resultados da ETr estimados pelo sensoriamento remoto.

Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

Irrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...

Uso de imagens orbitais no geoprocessamento algébrico da microrregião da Campanha Ocidental, Rio Grande do Sul

Floresta e Ambiente
Para analisar a transformação temporal da cobertura e do uso das terras de Campanha Ocidental no Rio Grande do Sul, utilizou-se um mosaico de imagens do satélite LANDSAT 5 (sensor Thematic Mapper), que recobre a região de estudo nos períodos de 1985 ...

Landscape drivers of scaled quail occurrence across a broad spatiotemporal scale: implications for habitat management

The Journal of Wildlife Management, EarlyView.
Combining large‐scale avian surveys with remote sensing products revealed landscape variables that likely limit scaled quail occurrence at the ecoregion scale in Texas. Promoting management practices that address ecoregion‐specific limiting factors may be key to averting further declines.

Cutting through the noise: What can habitat selection modeling teach us about caribou‐fire space use dynamics?

The Journal of Wildlife Management, EarlyView.
We synthesize the current knowledge regarding caribou habitat selection in relation to wildfires. Caribou responses to recent burns were generally weak and highly variable across subspecies or ecotypes, suggesting that post‐fire habitat selection is likely context‐dependent and the need for regionally adapted habitat management strategies.

Local and Tele‐Coupling Coordination Relationships Between Urban Resilience and Ecosystem Health in the Beijing‐Tianjin‐Hebei Region and Analysis of Their Influencing Factors

Land Degradation &Development, EarlyView.
ABSTRACT Urban resilience and ecosystem health are essential foundations for regional sustainable development, yet their coupled and coordinated relationships remain insufficiently explored at the urban‐agglomeration scale. Taking the 13 prefecture‐level cities in the Beijing‐Tianjin‐Hebei urban agglomeration as the study area and using panel data for ...
