SUMMARY Here we report a method for estimating ecosystem respiration (R e) by exclusive use of remotely sensed land surface temperature (T r) from NASA's moderate resolution imaging spectroradiometer (MODIS) sensors. A combination of daytime and nighttime MODIS T r data was used to model an 8-day mean value of land surface temperature (T r(mean)), which was then used in a modified Arrhenius-bas...

Land surface fluxes have been estimated from remotely sensed data at high pixel resolutions (approximately 60 m) with reasonable accuracy when compared to ground measurements (French et al., 2003; Kustas and Norman, 1999). The remote sensing input used to model land surface fluxes may consist of land surface temperature and a vegetation index. Remotely sensed land surface temperature estimates ...

The aim of this research is to explore the potentialities and limits integration remote sensing biophysical data (land surface temperature) in outdoor thermal comfort studies. Accordingly, by examining correlations between land temperature air temperature, using respectively satellite MODIS different weather stations archives alongside questionnaire surveys. Currently, parameters indices are us...

technique of remote sensing and its satellite products has many implementations in agricultural science and national resources. in this study, wheat yield in esfahan province, iran, were derived from modis satellite data over periods of 2000-2001(dry year) and 2004-2005 (wet year). for this purposes, 68 modis products of surface reflectance (mod09ga) and land surface temperature lst (mod11a2) o...

The overlapping of high-level cirrus cloud and low-level stratus cloud has posed a major challenge in determining their cloud top altitudes using passive satellite observations. Chang and Li (2005) present a novel satellite retrieval method that takes advantage of the Moderate Resolution Imaging Spectroradiometer (MODIS) data to detect the presence of overlapped cirrus and stratus clouds and de...

Land surface is normally considered as a mixture of soil and vegetation. Many applications, such as drought monitoring and crop-yield estimation, benefit from accurate retrieval of both soil and vegetation temperatures through satellite observation. A preliminary study has been conducted in this study on the estimation of land surface soil and vegetation component temperature using the geostati...

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 ...
