A Novel Global Grid Model for Atmospheric Weighted Mean Temperature in Real-Time GNSS Precipitable Water Vapor Sounding

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
The atmospheric weighted mean temperature (Tm) is an important parameter in calculating the precipitable water vapor from Global Navigation Satellite System (GNSS) signals. As both GNSS positioning and GNSS precipitable water vapor detection require high

Geostationary Satellite Observation of Precipitable Water Vapor Using an Empirical Orthogonal Function (EOF) based Reconstruction Technique over Eastern China

Remote Sensing, 2015
Water vapor, as one of the most important greenhouse gases, is crucial for both climate and atmospheric studies. Considering the high spatial and temporal variations of water vapor, a timely and accurate retrieval of precipitable water vapor (PWV) is ...

Diurnal cycle of precipitable water vapor over Spain [PDF]

Quarterly Journal of the Royal Meteorological Society, 2011
AbstractKnowledge of the diurnal cycle of precipitable water vapor (PWV) is very limited owing to the lack of data with sufficient temporal resolution. Currently, GPS receivers have proven to be a suitable technique to determine PWV diurnal variations. In this study, the annual and seasonal diurnal cycles of PWV have been obtained from GPS data for 10 ...

Tropical precipitation clusters as islands on a rough water‐vapor topography [PDF]

Quarterly Journal of the Royal Meteorological Society, 2021
AbstractTropical precipitation clusters exhibit power‐law frequency distributions in area and volume (integrated precipitation), implying a lack of characteristic scale in tropical convective organization. However, it remains unknown what gives rise to the power laws and how the power‐law exponents for area and volume are related to one another.

G-Band Vapor Radiometer Precipitable Water Vapor (GVRPWV) Value-Added Product [PDF]

, 2012
The G-Band Vapor Radiometer Precipitable Water Vapor (GVRPWV) value-added product (VAP) computes precipitable water vapor using neural network techniques from data measured by the GVR. The GVR reports time-series measurements of brightness temperatures for four channels located at 183.3 ± 1, 3, 7, and 14 GHz.

Research on variety characteristics of mainland China troposphere based on CMONOC

Geodesy and Geodynamics, 2018
In this research, we processed the GPS and meteorological data from about 220 stations of Crustal Movement Observation Network of China (CMONOC) observed in 2014 and derived the Zenith Total Delay (ZTD) map in both spatial and temporal dimension.

Estimation of the Precipitable Water and Water Vapor Fluxes in the Coastal and Inland Cities of China Using MAX-DOAS

Remote Sensing, 2021
Water vapor transport affects regional precipitation and climate change. The measurement of precipitable water (PW) and water vapor flux (WVF) is of great importance for the study of precipitation and water vapor transport.

Long-Term Trends of Astroclimatic Parameters above the Terskol Observatory

Atmosphere, 2023
Astroclimatic conditions characterize the quality of an astronomical site. The Terskol Observatory was founded over 42 years ago in 1980. The astronomical site (coordinates 43°16′29″ N, 42°30′03″ E) is located about 10 km from Mt.

Analysis on Characteristics of Radiosonde Bias Using GPS Precipitable Water Vapor [PDF]

Journal of Astronomy and Space Sciences, 2010
As an observation instrument of the longest record of tropospheric water vapor, radiosonde data provide upper-air pressure (geopotential height), temperature, humidity and wind. However, the data have some well-known elements related to inaccuracy.
