Developing a Multi-Band GNSS Remote Sensing Station To Measure Precipitable Water Vapor for Flash Flood Nowcasting
… offers an established alternative for measuring precipitable water vapor and is currently integrated into several numerical weather models. Recent research demonstrates that commercial-grade GNSS receivers can produce tropospheric products comparable to those from geodetic-grade equipment. The …

Atmospheric delay modeling for satellite laser altimetry
… allowed us to investigate the estimation of precipitable water vapor using GPS data. The validation studies have shown that our atmospheric delay algorithm errors are well within the ICESat error budget of 20 mm. The overall global delay errors are estimated to be approximately 5.4 mm and the …

Improving Convective Permitting Model Simulations of Extreme Precipitation using Object-Based Tracking and Data Assimilation
… to test the impact of assimilating GPS-derived Precipitable Water Vapor (PWV) using different densities of observation. Results from a 40-member WRF CPM ensemble are produced for two fairly different monsoon events in the year 2021, and demonstrate that assimilating bias-corrected synthetic PWV …

Arctic Cloud, Radiation and their Interactions with Sea Ice
… higher-than-average cloud fractions and cloud water paths result in increased downwelling longwave radiative flux at the surface, which triggers the initial melt of sea ice. In contrast, the late melt onset is usually linked to lower-than-average precipitable water vapor and downward longwave …

Broadband, millimeter-wave antireflection coatings for cryogenic sintered aluminum oxide optics
… 1998; Radford, 2011). A fifty year study of precipitable water vapor (PWV) at the South Pole found the average PWV is far less than 1 mm, making the South Pole one of the driest regions on Earth (Chamberlin and Grossman, 2012). This is important for telescopes observing at mm wavelengths, …
