Precipitable Water Vapor Retrieval from Shipborne GNSS Observations on the Korean Research Vessel ISABU

open access: yesSensors, 2020
We estimate precipitable water vapor (PWV) from data collected by the low-cost Global Navigation Satellite System (GNSS) receiver at a vessel. The dual-frequency GNSS receiver that the vessel ISABU is equipped with that is operated by the Korea Institute

Unusual vertical oscillations of a radiosonde

open access: yesWeather, EarlyView.
In summer 2023 in southern England, several unusual balloon launches were observed which descended for a few minutes before resuming ascent. This unusual vertical oscillation was repeated several times in a ‘roller‐coaster’‐like pattern. This article discusses the behaviour of the balloons.

Determination of Planetary Boundary Layer height with Lidar Signals Using Maximum Limited Height Initialization and Range Restriction (MLHI-RR)

open access: yesRemote Sensing, 2020
The planetary boundary layer height (PBLH) is a vital parameter to characterize the surface convection, which determines the diffusion of air pollutants.

Advanced Grid Model of Weighted Mean Temperature Based on Feedforward Neural Network Over China

open access: yesEarth and Space Science, 2021
Weighted mean temperature (Tm) is a key parameter in Global Navigation Satellite System meteorology. In this study, European Centre for Medium‐Range Weather Forecasts Re‐Analysis product with a spatial resolution of 0.5° × 0.5° from 1999 to 2018 was used

The 2026 cold wave brought northern Fennoscandia its coldest 2‐week period since 1987

open access: yesWeather, EarlyView.
During late December 2025 and January 2026, a severe and long‐lasting cold wave affected northern Fennoscandia. In this article, we aim to quantify the extremity of the 2026 cold wave and evaluate the atmospheric conditions that led to the persistent cold anomalies.

Assessment of the Accuracy of the Saastamoinen Model and VMF1/VMF3 Mapping Functions with Respect to Ray-Tracing from Radiosonde Data in the Framework of GNSS Meteorology

open access: yesRemote Sensing, 2020
In this paper, we assess, in the framework of Global Navigation Satellite System (GNSS) meteorology, the accuracy of GNSS propagation delays corresponding to the Saastamoinen zenith hydrostatic delay (ZHD) model and the Vienna Mapping function VMF1/VMF3 (

The Earth's Greatest Porous Media

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?

Analysis Of Temperature Vertical Profile And Indication Of Inversion Layers In Radiometer Synoptic And Radiosonde At Kototabang

open access: yes, 2011
Radiometer that operated in Kototabang-West Sumatra observed vertical temperature profiles. In this paper, we analyzed the vertical structure of seasonal temperatures and the presence of an inversion layer of each data observation for a period of five ...

Homogenized radiosonde record at station Ny-Ålesund, Spitsbergen, 2023-2025

open access: yes
The presented data build on the homogenized radiosonde data set 1993 to 2022 at the Arctic site Ny-Ålesund (78.9°N, 11.9°E), Svalbard, which corrected discontinuities in the instrumentation by correcting known errors in the Manufacturer-provided profiles.
