Hybrid precipitable water vapor fusion model in China
Journal of Atmospheric and Solar-Terrestrial Physics, 2020Abstract High-precision precipitable water vapor (PWV) can be obtained using the global navigation satellite system (GNSS). However, the spatial resolution of the GNSS-derived PWV is insufficient, particularly for areas without sufficient GNSS stations. Although other techniques, such as radiosonde sounding, can also be used to obtain PWV, generating

Precipitable Water Vapor at Mount-Laguna Observatory
Publications of the Astronomical Society of the Pacific, 1987Measurements of precipitable water vapor at Mount Laguna Observatory are presented and discussed. A total of 243 measurements were made from March 1983 through December 1985. The method, using a filter-wheel radiometer in conjunction with spectrographic calibration, is described. The mean value of precipitable water vapor on photometric days was 5.2 mm.

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

Increasing trend of Precipitable Water Vapor in Antarctica and Greenland
2022<p>Polar precipitable water vapor (PWV) is expected to increase under a warming climate. However, the conventional approach cannot provide sufficient long-term PWV records due to the high maintenance costs. Fortunately, the exponential explosion in the number of geodetic-quality Global Navigation Satellite System (GNSS) stations has ...

Estimation of Water Vapor Profiles from Total Precipitable Water.
1983Abstract : A method is described for converting a value of total precipitable water into an approximate mixing ratio profile. Mixing ratios are provided at the six radiosonde mandatory reporting levels. The method uses an approximation based on the empirical orthogonal functions (EOF's) of mixing ratio profiles.

Accuracy Assessment of MODIS Derived Precipitable Water Vapor
2018 IEEE Asia-Pacific Conference on Antennas and Propagation (APCAP), 2018In this paper, precipitable water vapor (PWV) values calculated from MODIS satellite data are compared to the PWV values calculated from GPS data. Analysis of one-year data from 9 stations, shows that the MODIS derived PWV values correlate well with the GPS PWV values with the correlation coefcients of 0.85, 0.94 and 0.85 for tropical, sub-tropical and

Development of real-time precipitable water vapor monitoring system
2013 3rd International Conference on Instrumentation, Communications, Information Technology and Biomedical Engineering (ICICI-BME), 2013The development of a real-time system to monitor the precipitable water vapor (PWV) using surface meteorological data as the input is reported in this paper. The PWV value is estimated using the, adaptive neuro fuzzy inference system (ANFIS) model that was generated using the Matlab™ software. The input of the model was taken based on the data measured

Validation on MERSI/FY-3A precipitable water vapor product
Advances in Space Research, 2018Abstract The precipitable water vapor is one of the most active gases in the atmosphere which strongly affects the climate. China's second-generation polar orbit meteorological satellite FY-3A equipped with a Medium Resolution Spectral Imager (MERSI) is able to detect atmospheric water vapor.

Abstract SOFIA was an airborne observatory for far-infrared astronomy stationed at the Armstrong Flight Research Center in Palmdale, CA, USA. Although SOFIA flew at altitudes of ∼41,000 ft, any far-infrared observations from within the Earth’s atmosphere are nevertheless hampered by water vapor absorbing the astronomical signal.

Thirty Meter Telescope Site Testing X: Precipitable Water Vapor
Publications of the Astronomical Society of the Pacific, 2010The results of the characterization of precipitable water vapor in the atmospheric column carried out in the context of identifying potential sites for the deployment of the Thirty Meter Telescope (TMT) are pre- sented. Prior to starting the dedicated field campaign to look for a suitable site for the TMT, candidate sites were selected based on a ...
