Obtaining measurements of the near-surface soil water content from passive microwave observations requires knowledge of the soil effective temperature, which is a function of the soil temperature and moisture profiles. Detailed information on these profiles is not available from airborne remote sensing, but the effective temperature can be estimated via thermal infrared observations of the land...

The soil moisture content is of great importance for numerical weather forecasts and has been identified as one of the parameter products of EUMETSAT’s Satellite Application Facility on Land Surface Analysis (Land SAF). Soil moisture strongly affects the surface energy balance and therefore near surface temperature and humidity. Conversely, temperature observations may be used to infer the soil...

Species living under large thermal fluctuations possibly need more flexible physiological capabilities than species living in more stable thermal environments. Deep-soil dwelling species habituate more stable thermal environments than surface dwelling species. We compared the flexibility of lipid composition in response to two acclimation temperatures of soil (4), near surface (2), and surface ...

so far a number of works on the heat flux anomalies of the earth surface based on the satellite images and underground water as seismic precursors have been carried out. in this paper the soil temperature data at 1m depth (deep enough to filter temperature variation due to high frequency meteorological forcings) has been considered to see if there are connections between earthquakes in bam and ...

Global warming influences a series of ecological processes and ecosystems' stability. Although comprehensive studies have been done to investigate responses of various ecosystem processes to rising air temperatures, less is known about changes in soil temperatures and their impact on below-ground processes, particularly in deep layers. Herein, we used 50 y of temperature data (1962-2011) from 3...

Near-surface soil moisture is an important parameter in hydrological, meteorological and agricultural applications. Passive microwave observations, both airborne and satellite, can be used to infer near-surface soil moisture. The brightness temperature of the thermal radiation that crosses the soil–air interface is the product of the soil emissivity and the effective temperature. At L-band, the...

Numerous studies have investigated the direct retrieval of soil properties, including soil texture, using remotely sensed images. However, few have considered how soil properties influence dynamic changes in remote images or how soil processes affect the characteristics of the spectrum. This study investigated a new method for mapping regional soil texture based on the hypothesis that the rate ...

In predicting wheat (Triticum aestivum L.) phenology, logic suggests that basing thermal unit accumulation on near-surface soil temperature should give a better representation of shoot apex thermal unit accumulation than air temperature until internode elongation raises the apex above the soil surface. A study was undertaken to determine if predictions of winter wheat phenology are improved whe...

Urban areas are major contributors to air pollution and climate change, causing impacts on human health that are amplified by the microclimatological effects of buildings and grey infrastructure through the urban heat island (UHI) effect. Urban greenspaces may be important in reducing surface temperature extremes, but their effects have not been investigated at a city-wide scale. Across a mid-s...
