چکیده

As one of urban eco-environmental contents, urban heat island is very significant. Nowadays, the temperature in urban is higher than the surrounding natural terrain, as the result of vegetation cover declining and impervious surface increasing, coupled with the influence of anthropogenic heat discharge. In recent years, it is possible to study the urban heat island and its formation mechanism, owing to the rapid development of quantitative remote sensing technology. The earth surface parameters can be retrieved from thermal infrared remote sensing data, supplemented by meteorological data of ground-based observations, so the formation mechanism of urban heat island can be analyzed quantitatively. Urban storage heat flux is an important parameter of heat-island formation mechanism analysis; therefore, its precise estimate is of great significance for the urban heat environment monitoring and improvement and regulation of the living environment.

Surface Heat Balance Analysis of Tainan City on March 6, 2001 Using ASTER and Formosat-2 Data

The urban heat island phenomenon occurs as a mixed result of anthropogenic heat discharge, decreased vegetation, and increased artificial impervious surfaces. To clarify the contribution of each factor to the urban heat island, it is necessary to evaluate the surface heat balance. Satellite remote sensing data of Tainan City, Taiwan, obtained from Terra ASTER and Formosat-2 were used to estimat...

Soil Moisture Estimation in Rangelands Using Remote Sensing (Case Study: Malayer, West of Iran)

Soil moisture is generally regarded as the limiting factors in rangeland production. Although many studies have been conducted to estimate soil moisture in semiarid areas, there is little information on mountainous rangelands in west of Iran. The present study aims to investigate the soil moisture estimation in rangelands as compared to the other land uses over a mountainous area in central Zag...

Urban Heat Island Analysis Using the Landsat TM Data and ASTER Data: A Case Study in Hong Kong

In this paper, the effect of urban heat island is analyzed using the Landsat TM data and ASTER data in 2005 as a case study in Hong Kong. Two algorithms were applied to retrieve the land surface temperature (LST) distribution from the Landsat TM and ASTER data. The spatial pattern of LST in the study area is retrieved to characterize their local effects on urban heat island. In addition, the co...

A Modified Multi-Source Parallel Model for Estimating Urban Surface Evapotranspiration Based on ASTER Thermal Infrared Data

To date, little attention has been given to remote sensing-based algorithms for inferring urban surface evapotranspiration. A multi-source parallel model based on ASTER data was one of the first examples, but its accuracy can be improved. We therefore present a modified multi-source parallel model in this study, which has made improvements in parameterization and model accuracy. The new feature...
