In this work we present the results of an experiments carried out to map the temporal evolution of the Precipitable Water Vapor (PWV) using interferometric SAR and GPS data. SAR interferometry gives information on PWV with a more dense and regular spatial distribution than GPS measurements. The ...
Here, we analyse the relationship between atmospheric water vapour content and SAT using precipitable water vapour (PWV) derived from global positioning system satellites. A super-CC rate appears in hourly PWV when the SAT is below 16 °C, whereas the rate decreases at high SAT, which is ...
16.The forecast map of total water vapor content (called precipitable water) for Saturday morning is shown below. 17.A new instrument for measuring the total precipitable water in the atmosphere is introduced. 介绍一种测量大气水汽总量的新方法和仪器. 相关词 Aetobatus aggrandisement aerophilic AF...
Total precipitable water (TPW), the amount of water vapor in a column from the surface of the earth to space, is used by forecasters to predict heavy precipitation. In this paper, a process for blending TPW values retrieved from two satellite sources is detailed: the Advanced Microwave Soundi...
GPS-based atmospheric precipitable water vapor estimation using meteorological parameters interpolated from NCEP global reanalysis data. Journal of Geophysical Research, doi: 10.1029/2007JD008758.Jade, S., and Vijayan, M. S. M.: GPS-based atmospheric precipitable water vapor estimation using ...
This product is constructed by merging all valid TPW (water vapor) data from SSM/I, SSMIS, AMSR-E, WindSat, and AMSR2 instruments. The netCDF file contains mean total precipitable water (TPW) values on a 1-degree grid, a 12-month TPW climatology, monthly anomalies, a TPW trend map, ...
Among them, atmospheric phase delays caused by changes in the distribution of water vapor can lead to biased model parameter estimates and/or to difficulties in interpreting deformation events captured with InSAR. The hyper-arid climate of northern Chile might suggest that differential delays are of ...
Precipitable water vapor (PWV) is an important parameter in Earth’s atmosphere, and its spatiotemporal variations influence Earth’s energy transfer and weather changes. PWV can be monitored and retrieved by plenty of techniques with varying spatiotemporal resolutions, accuracies, and systematic biase...
We studied the assimilation of high-resolution precipitable water vapor (PWV) data derived from a hyper-dense global navigation satellite system network around Uji city, Kyoto, Japan, which had a mean inter-station distance of about 1.7 km. We focus
However, GPS PWV derivation requires surface pressure to calculate the precise zenith hydrostatic delay and weighted mean temperature to map the zenith wet delay to precipitable water vapor. GPS stations without collocated meteorological sensors can retrieve water vapor using standard atmosphere parameters,...
