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.

Precision analysis on the weighted mean temperature of the atmosphere grid data offered by GGOS Atmosphere in Xinjiang

SPIE Proceedings, 2015
As the fact that most of the ground-based GPS lacks of the detection of the upper-air meteorological data, thus the application of ground-based GPS sensing of water vapor technology has been limited due to the inaccurately calculated weighted mean temperature.

Model Establishment of Atmospheric Weighted Mean Temperature in Chongming Eco-Island and Its Application During Typhoon Lekima

2021
Chongming Eco-Island is the largest estuarine alluvial island in the world, which is very important to Shanghai and the Yangtze River Delta economic belt. Due to the special geographical location of Chongming, it is affected by typhoons almost every year, which have caused serious damage to the ecological environment and economic development. A typhoon

A new global grid model for the determination of atmospheric weighted mean temperature in GPS precipitable water vapor

Journal of Geodesy, 2018
In ground-based global positioning system (GPS) meteorology, atmospheric weighted mean temperature, $$T_\mathrm{m}$$ , plays a very important role in the progress of retrieving precipitable water vapor (PWV ...

A Deep Learning–Based Regional Atmospheric Weighted Mean Temperature Model for China

Journal of Global Positioning Systems
To further enhance the accuracy of atmospheric weighted mean temperature (Tm) models in ground-based Global Navigation Satellite System (GNSS) retrieval of precipitable water vapor (PWV), we propose and develop a regionally adaptive Multi-Hidden-Layer neural network for Tm, hereafter referred to as MHL_Tm.

Multi-scale accuracy evaluation and adaptability analysis of different atmospheric weighted mean temperature models in China

Journal of Applied Geodesy
Abstract The atmospheric weighted mean temperature (Tm) plays a critical role in deriving precipitable water vapor (PWV) from zenith wet delay (ZWD) in GNSS meteorology. Although numerous empirical Tm models have been rigorously validated at regional and global scales, their applicability and reliability across China remain ...
