Thermal imagery is widely used to quantify land surface temperatures to monitor the spatial extent and thermal intensity of the urban heat island (UHI) effect. Previous research has applied Landsat images, Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) images, Moderate Resolution Imaging Spectroradiometer (MODIS) images, and other coarseto medium-resolution remotely sens...

The interaction between sea and atmosphere has profound effects on the regions climate. Meanwhile, the sea surface temperature is considered as one of the most effective components of water bodies, and the controller of many atmospheric behaviors. Because of the importance of sea surface temperatures effects on atmospheric elements and also given the role of global warming on land and sea surfa...

Sensitivity analysis of temperature-emissivity separation method commonly applied to hyperspectral data to various sources of errors is performed in this paper. In terms of resulting errors in the process of retrieving surface temperature, results show that: (1) Satisfactory results can be obtained for heterogeneous land surfaces and retrieval error of surface temperature is small enough to be ...

temperature is considered as the basic element of climate and also the environmental limiting factor in lutdesert. in this research, in order to identify the temperature of lut desert located in east of central iran, using remote sensing data, six series of modis sensor images related to june 24th & december 23rd 2002, and also january 22nd, march 22nd, june 22nd & september 24th 2003 w...

The surface air temperature response to vegetation changes has been studied for the extreme case of land-cover change1–5; yet, it has never been quantified for the slow but persistent increase in leaf area index (LAI) observed over the past 30 years (Earth greening)6,7. Here we isolate the fingerprint of increasing LAI on surface air temperatureusinga coupled land– atmosphere global climate mod...

Abstract: As long as the effective contributions of satellite images in the continuous monitoring of the wide area and long range of time period, Landsat TM and Landsat ETM+ satellite images are surveyed. After quantization and classification of the deviations between TM and ETM+ images based on approved thresholds such as gains and biases or offsets, a correlation analysis method for the compa...

LWP can be retrieved from the microwave signature emitted by cloud droplets. Microwave retrievals of cloud LWP are not applicable over land because of the strong and highly variable microwave emission of the land surface. The emission from ocean surfaces is relatively weak and less variable so cloud LWP can be estimated from satellite observed microwave radiances. However, the accuracy is signi...

HadISDH.2.0.0 is the first gridded, multi-variable humidity and temperature in situ observations-only climatedata product that is homogenised and annually updated. It provides physically consistent estimates for specific humidity, vapour pressure, relative humidity, dew point temperature, wet bulb temperature, dew point depression and temperature. It is a monthly mean gridded (5 by 5) product w...
