A method of inserting and mending for the GPS precipitable water vapor
2011 International Conference on Multimedia Technology, 2011The construction of the water vapor monitoring by ground-based GPS network in our country is still at the starting stage at present and some technology is still unripe . If there are some data in which GPS original data or the surface meteorological elements are lacked, it is unable to calculate out precipitable water vapor by GPS.

Precipitable Water Vapor in Atmospheres Characterized by Temperature Inversions
Journal of Applied Meteorology, 1977Abstract The total atmospheric precipitable water W has been measured with an infrared hygrometer for different atmospheric conditions and various seasons. Related to the simultaneous dew-point temperature Td at the surface, these data indicate that correct estimates of W can be given by the relationship lnW = a + b Td [first proposed by Reitan (1963)]

GNSS Precipitable Water Vapour for Climate Monitoring
Aside from main geodetic applications, the Global Navigation Satellite System (GNSS) is now an established observing system for atmospheric water vapour which is the most important greenhouse gas as it is responsible for around 60% of the natural greenhouse effect. Water vapour is under-sampled in the current climate-observing systems.Jens Wickert +4 more

Precipitable water vapor content above Pico Veleta
Publications of the Astronomical Society of the Pacific, 1989Radiometric measurements of the precipitable water vapor content (PWV) above Pico Veleta, Sierra Nevada, Spain, are presented. The study includes measurements carried out on 180 days and 118 nights during the years 1984 through 1987. Average annual values of daytime and nighttime PWV of 3.7 mm and 2.1 mm, respectively, are found; the annual average PWV

The Precipitable Water Vapor at the Lenghu Site on the Tibetan Plateau
Research in Astronomy and AstrophysicsAbstract Site characterization studies have identified Lenghu site as a world-class location for optical-infrared astronomy owing to exceptional atmospheric conditions. The spatial distribution of precipitable water vapor (PWV) and its altitudinal variations are crucial for observatory siting strategies.

A Simplified Model for the Retrieval of Precipitable Water Vapor From GPS Signal
IEEE Transactions on Geoscience and Remote Sensing, 2017In this paper, a simplified latitude and day-of-year (DoY)-based model is proposed for the retrieval of precipitable water vapor (PWV) from global positioning system (GPS) signal. Conventionally, PWV, the total amount of water in a vertical column of a unit cross-sectional area, is estimated from the GPS signal delay and a dimensionless conversion ...
