Performance evaluation of regional weather predictions with the Model for Prediction Across Scales – Atmosphere (MPAS‐A) over the Maritime Continent

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
As part of the ongoing efforts to develop next‐generation forecasting systems at the Meteorological Service Singapore, this study presents the setup and evaluation of the SINGV_NG(MPAS) system. Overall, the SINGV_NG(MPAS) system outperforms European Centre for Medium‐Range Weather Forecasts (ECMWF) deterministic forecasts in capturing heavy rainfall ...

Analysis on atmospheric profiles retrieved from microwave radiometer observation at Ganzi in the eastern Qinghai-Tibet Plateau

open access: yes暴雨灾害, 2019
Microwave radiometer (MWR) can retrieve atmospheric profiles with a temporal resolution of several minutes, which compensates for the low temporal resolution of the meteorological radiosonde data.

Improving the Wet Refractivity Estimation Using the Extremely Learning Machine (ELM) Technique

open access: yesAtmosphere, 2023
Constructing accurate models that provide information about water vapor content in the troposphere improves the reliability of numerical weather forecasts and the position accuracy of low-cost Global Navigation Satellite System (GNSS) receivers. However,

Major Melting Event on the Ross Ice Shelf, Antarctica, Connected With Enhanced Atmospheric Turbulence

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The Ross Ice Shelf (RIS) in West Antarctica experienced extensive surface melting in January 2016, driven by warm humid air transported from over the Southern Ocean. Few studies have reported increased atmospheric water vapor and turbulent mixing during this event in this region, where the availability of surface measurements is challenging ...

Six-month ground-based water vapour raman lidar measurements over Athens, Greece and system validation [PDF]

open access: yes, 2007
Water vapour is one of the most important greenhouse gases, since it causes about two third of the natural greenhouse effect of the Earth's atmosphere. To improve the understanding of the role of the water vapour in the atmosphere, extensive water vapour

Validation of the Atmospheric Boundary Layer Height Estimated from the MODIS Atmospheric Profile Data at an Equatorial Site

open access: yesAtmosphere, 2020
The atmospheric boundary layer height is important for constraining air pollution and meteorological models. This study attempted to validate the MODIS-estimated atmospheric boundary layer height (ABLH), and variation in the ABLH in Uganda was evaluated.

Investigation of Antarctic Precipitable Water Vapor Variability and Trend from 18 Year (2001 to 2018) Data of Four Reanalyses Based on Radiosonde and GNSS Observations

open access: yesRemote Sensing, 2021
Precipitable water vapor (PWV) plays a vital role in climate research, especially for Antarctica in which meteorological observations are insufficient due to the adverse climate and topography therein. Reanalysis data sets provide a great opportunity for

Listening to the Atmosphere: Using Infrasound Observations to Infer Atmospheric Conditions

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract The stratosphere and mesosphere are important regions for the prediction of weather at the Earth's surface for medium‐ and long‐range forecasts. The availability of observations in these layers is lower than that of the troposphere, especially for the dynamics. While seeking new observational sources is important, there are existing infrasound

Miniaturized atmospheric ionization detector [PDF]

open access: yes, 2018
A small scintillator-based detector for atmospheric ionization measurements has been developed, partly in response to a need for better ionization data in the weather-forming regions of the atmosphere and partly with the intention of producing a ...
