A globally applicable, season-specific model for estimating the weighted mean temperature of the atmosphere

Journal of Geodesy, 2012
In GPS meteorology, the weighted mean temperature is usually obtained by using a linear function of the surface temperature Ts. However, not every GPS station can measure the surface temperature. The current study explores the characteristics of surface temperature and weighted mean temperature based on the global pressure and temperature model (GPT ...

Calculation method of mean skin temperature weighted by temperature sensitivity of various parts of human body

Journal of Thermal Biology, 2021
Skin temperature is an important physiological parameter, and its calculation methods are varied, and the results are different. At present, the area weighting method is mostly used to calculate the mean skin temperature. However, the skin of various parts of the human body has different degrees of sensitivity to temperature changes.

Mean weighted temperature for PWV estimation

2015 IEEE 4th Asia-Pacific Conference on Antennas and Propagation (APCAP), 2015
In this paper, the effects of mean weighted temperature (Tm) for the calculation of perceptible water vapor (PWV) from GPS data is analyzed. Tm for Singapore is estimated using surface temperature information (Ts). To analyze the effect of Tm for calculating PWV, PWV for four consecutive months are calculated using the estimated equation and compared ...

A Study of the Atmospheric Weighting Mean Temperature in Northwest Plateau of China

Applied Mechanics and Materials, 2011
The data from 11 meteorological radiosonde stations in 5 provinces including Shanxi, Shaanxi, Ningxia, Inner Mongolia and Hebei are divided into 9 different data collections which are used to deduce the linear regression models of atmospheric weighting mean temperature (Tm) for Ground-based GPS precipitable water vapor (PWV) retrieval.

A new weighting system for mean surface temperature of the human body

Journal of Applied Physiology, 1964
On the basis of an analysis of the skin temperature data on three resting human subjects from 112 experiments, a simple weighting system for computing the mean skin temperature from observations on four areas of the body, namely, chest, arms, thighs, and legs, has been proposed.

Weighted mean temperature model for extra tropical region of India

Journal of Atmospheric and Solar-Terrestrial Physics, 2014
Abstract The Global Positioning System (GPS) estimates Precipitable Water Vapor (PWV) from Zenith Wet Delay (ZWD) using a key parameter called water vapor weighted mean temperature ( T m ) of the atmosphere. However, T m must be tuned to the specific area and location.

A neural network model for predicting weighted mean temperature

Journal of Geodesy, 2018
Water vapor is an important element of the Earth’s atmosphere, and most of it concentrates at the bottom of the troposphere. Knowledge of the water vapor measured by Global Navigation Satellite Systems (GNSS) is an important direction of GNSS research. In particular, when the zenith wet delay is converted to precipitable water vapor, the weighted mean ...

The effect of skin thermistor fixation method on weighted mean skin temperature

Physiological Measurement, 2011
The purpose of this study was to investigate the effect of three different skin thermistor attachment methods on weighted mean skin temperature (WMT(sk)) at three different ambient temperatures (approximately 24 °C (TEMP); approximately 30 °C (WARM); approximately 35 °C (HOT)) compared to uncovered thermistors.

Agreement between mean weighted skin temperature formulas during exercise

Journal of Applied Physiology
This investigation is the first to show T mws formula agreement during exercise in moderate (20°C) and warm (30°C) environments. This study uniquely contributes to the present knowledge by showing better agreement between all formulas and the criterion in the 30°C environment than in the 20°C
