Interpreting the results of a high-level clouds (HLCs) lidar study requires comparison with vertical profiles meteorological quantities. There are no regular radiosonde measurements quantities in Tomsk. The nearest aerological stations several hundred kilometers away from and perform only few times day, whereas experiments performed continuously throughout day. To estimate conditions at HLC alt...
From late 2019 to early 2020, forest fires in southeastern Australia caused huge economic losses and environmental pollution. Monitoring has become increasingly important. A new method of fire detection using the difference between global navigation satellite system (GNSS)-derived precipitable water vapor radiosonde-derived (?PWV) is proposed. To study feasibility method, relationship studied p...
Extremely dry conditions characterized by amounts of precipitable water vapor (PWV) as low as 1–2 mm commonly occur in high-latitude regions during the winter months. While such dry atmospheres carry only a few percent of the latent heat energy compared to tropical atmospheres, the effects of low vapor amounts on the polar radiation budget—both directly through modulation of longwave radiation ...
Radiosonde data have been used, and will likely continue to be used, for the detection of temporal trends in tropospheric and lower-stratospheric temperature. However, the data are primarily operational observations, and it is not clear that they are of sufficient quality for precise monitoring of climate change. This paper explores the sensitivity of upper-air temperature trend estimates to se...
Abstract. Ceilometer measurements of aerosol backscatter profiles have been widely used to provide continuous planetary boundary layer height (PBLHT) estimations. To investigate the robustness ceilometer-estimated PBLHT under different atmospheric conditions, we compared ceilometer- and radiosonde-estimated PBLHTs using multiple years U.S. Department Energy (DOE) Atmospheric Radiation Measureme...
