Anthropogenic Heat (AH) emissions modify the energy balance in urban areas and is crucial for microclimate modelling improved weather forecast modelling. Therefore, present study conducted on Delhi its surroundings firstly aims to estimate AH using Earth Observation (EO) data of Landsat 8 then, evaluate impact detailed roughness parameterization estimation further validate obtained flux values ...

A novel measurement technique, based on infrared thermography, has been applied for characterizing the thermal properties of paper with high spatial resolution. The technique is termed as ‘active thermography’ since the temperature response of a paper sheet is observed and analyzed with respect to an external periodic heating. Through the analysis of the temperature response of the paper surfac...

A new estimate of the heat budget for the North Pacific Ocean is presented in this paper. The seasonal net heat flux and heat storage rates were calculated for the North Pacific Ocean from 1950 to 1990 on a spatial resolution of 58 3 58. Temperature profiles from the National Ocean Data Center were used to calculate the heat storage rates. Satellite remotely sensed solar irradiance and ship mar...

most of the methods that have been proposed for speed estimation of induction machines require the rotor and the stator resistance to change in the normal operating range. on the other hand, estimation of the rotor resistance requires rotor speed. in this paper, after studying conditions for simultaneous estimation of rotor speed and rotor resistance, a method for simultaneous estimation of rot...

8 Definitions 9 Heat flow. The rate of thermal energy transfer in a medium 10 driven either conductively along a thermal gradient or 11 advectively via mass transport. The standard unit is 12 watts, W. The term is also used to describe a subdiscipline 13 of geophysics, as in the title of this entry. 14 Conductive heat flux. The heat flow per unit area diffusing 15 by conduction along a thermal ...

In this paper, the combination of conduction with radiation into a semitransparent medium which includes absorption, emission and scattering has been investigated. In order to Study the conduction in medium, the Non-Fourier heat conduction has been applied. In this model there is a time delay between heat flux and temperature gradient. Also, in contrast with Fourier heat conduction, the speed o...

This paper extends previous large-eddy simulations of the convective boundary layer over a surface with a spatially varying sensible heat flux. The heat flux variations are sinusoidal and onedimensional. The wavelength is 1500 or 4500 m (corresponding to 1.3 and 3.8 times the boundarylayer depth. respectively) and the wind speed is 0. 1 or 2 m sI. In every case the heat flux variation drives a ...

Heat flux plates are commonly used to measure soil heat flux, a component of the surface energy balance. The plate method is simple and precise, but several previous studies have demonstrated the potential for relatively large errors. Here we present the results of in situ tests of the plate method, and we describe some promising alternative methods. Summertime soil heat flux was measured with ...
