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

Altitude dependence of atmospheric temperature trends: Climate models versus observation [PDF]

open access: yes, 2004
As a consequence of greenhouse forcing, all state of the art general circulation models predict a positive temperature trend that is greater for the troposphere than the surface.

Intercomparison of CL31 and CL51 ceilometers and impact of installation angle on cloud base height measurement agreement

open access: yesWeather, EarlyView.
Lowest‐layer cloud base height (CBH) measurements obtained between July 2018 and December 2019 from four ceilometers at the Korea Standard Meteorological Observatory were compared to determine how ceilometer installation angle differentially affects CBH measurements.

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 (

Impacts to the mountain‐valley circulation from the 2023 annular solar eclipse

open access: yesWeather, EarlyView.
In October 2023, as part of the Nationwide Eclipse Ballooning Project (NEBP), faculty and students from the University of North Dakota (UND) in coordination with Pueblo Community College Southwest collected weather observations during an annular solar eclipse colloquially known as a ‘ring of fire’ eclipse.

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?

Wilson's Atmospheric Electron Accelerator: A Centennial Perspective

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract As of the time of writing this letter, we mark the centennial of Wilson's runaway electrons proposed in 1925. Owing to instrumentation limitations, Wilson and his students could not detect the particles anticipated by theory Chilingarian et al. (2025, https://doi.org/10.1029/2024jd042350).

Data Fixing Algorithm in Radiosonde Monitoring Process

open access: yesJournal of Telecommunications and Information Technology, 2017
Earth surface monitoring can give information that may be used in complex analysis of the air conditions, temperature, humidity etc. Data from a vertical profile of the atmosphere is also essential for accurate thunderstorm forecasting.

Toward Closing the Hydroxyl Radical (OH) Budget: Assessing the Feasibility and Uncertainties in Constraining primary OH Production From Space

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Recent progress in constraining the atmosphere's primary oxidant, the hydroxyl radical (OH), with machine learning (ML) and satellite data raises the intriguing possibility of also constraining individual OH chemical production and loss terms.

Airborne Lidar measurements of the atmospheric pressure profile with tunable Alexandrite lasers [PDF]

open access: yes, 1986
The first remote measurements of the atmospheric pressure profile made from an airborne platform are described. The measurements utilize a differential absorption lidar and tunable solid state Alexandrite lasers. The pressure measurement technique uses a
