On the existence of an extraterrestrial source of water vapor in the middle atmosphere
Geophysical Research Letters, 1986 Observations of the ultraviolet dayglow of atomic oxygen from the DE‐1 spacecraft (Frank et al., 1986a,b) have revealed the existence of frequent localized decreases ("holes") in the emitted intensity. These have been interpreted as evidence of a steady influx of small "comets" whose icy envelope would provide a source of H2O molecules in the upper ...

Water, 2022 Abstract This study investigated the hydrogen-oxygen stable isotope characteristics of different water bodies, from the perspectives of elevation, season, and interannual variation, using water samples of atmospheric precipitation, river water, groundwater, and ice–snow meltwater obtained in the Ili Kashi River Basin from July 2018 to June 2021.

G305.8 - 0.2 water vapor source - A young object
The Astronomical Journal, 1991 Observations of water vapor and silicon monoxide masers were conducted in the direction of G305.8−0.2. No SiO maser emission above 7 Jy of flux density was detected. The short-time variability of the H 2 O maser together with the absence of compact radio continuum emission suggests that the excitation energy of the maser could originate from an O7-O9 ...

Modeling insights into deuterium excess as an indicator of water vapor source conditions [PDF]
Journal of Geophysical Research: Atmospheres, 2013 Deuterium excess (d) is interpreted in conventional paleoclimate reconstructions as a tracer of oceanic source region conditions, such as temperature, where precipitation originates. Previous studies have adopted coisotopic approaches (using both δ18O and d) to estimate past changes in both site and oceanic source temperatures for ice core sites using ...

Comparative Analysis of Individual Water Vapor Sources in Dry and Wet Year in Southwest China
Gaoyuan qixiang, 2023 The climate of Southwest China is wet all year round， but the frequent drought disasters in recent years have caused huge economic losses such as crop yield reduction and forest fire.In order to fully understand the anomalies of water vapor transport in ...

Water Vapor Sources of the October 2000 Piedmont Flood
Journal of Hydrometeorology, 2004 Abstract Very intense mesoscale or synoptic-scale rainfall events can occasionally be observed in the Mediterranean region without any deep cyclone developing over the areas affected by precipitation. In these perplexing cases the synoptic situation can superficially look similar to cases in which very little precipitation occurs.

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
