Ionospheric Variations Induced by Thunderstorms in the Central Region of Argentina during the RELAMPAGO–CACTI Campaign
The ionosphere can be perturbed by solar and geomagnetic activity, earthquakes, thunderstorms, etc. In particular, electromagnetic pulses produced by thunderstorms can generate wave structures in the ionospheric plasma, which are known as atmospheric gravi ...
2023MoMuCAMS: A new modular platform for boundary layer aerosol and trace gas vertical measurements in extreme environments
Julia Schmale, Andrea Baccarini, Roman Pohorsky
The Modular Multiplatform Compatible Air Measurement System (MoMuCAMS) is a newly developed in situ aerosol and trace gas measurement payload for lower atmospheric vertical profiling in extreme environments. MoMuCAMS is a multiplatform compatible system, p ...
2023Nitrogen oxides in the free troposphere: implications for tropospheric oxidants and the interpretation of satellite NO2 measurements
Ilann Ernest Valentin Bourgeois
Satellite-based retrievals of tropospheric NO(2)columns are widely used to infer NOx (equivalent to NO + NO2) emissions. These retrievals rely on model information for the vertical distribution of NO2. The free tropospheric background above 2 km is particu ...
COPERNICUS GESELLSCHAFT MBH2023Australian Bushfires (2019-2020): Aerosol Optical Properties and Radiative Forcing
In the present study, we present the aerosol optical properties and radiative forcing (RF) of the tropospheric and stratospheric smoke layers, observed by the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite, during the ...
2022Multiphase processes in the EC-Earth model and their relevance to the atmospheric oxalate, sulfate, and iron cycles
Understanding how multiphase processes affect the iron-containing aerosol cycle is key to predicting ocean biogeochemistry changes and hence the feedback effects on climate. For this work, the EC-Earth Earth system model in its climate-chemistry configurat ...
COPERNICUS GESELLSCHAFT MBH2022Annual aerosol chemical composition retrieved from an aerosol mass spectrometer in the central Arctic
Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Hélène Paule Angot, Lubna Dada
The Arctic environment is transforming rapidly due to climate change, which induces several feedback processes such as retreating sea ice, changing atmospheric transport patterns and cloud formation. In addition, more local pollution due to shipping and re ...
2022Chemical evolution of primary and secondary biomass burning aerosols during daytime and nighttime
Athanasios Nenes, Satoshi Takahama, Spyros Pandis, Amir Yazdani
Fine particulate matter (PM) affects visibility, climate, and public health. Biomass burning (BB) in the forms of residential wood burning, wildfires, and prescribed burning is a major source of primary and secondary organic matter (OM, an important fracti ...
2022Breaking of Internal Waves and Turbulent Dissipation in an Anticyclonic Mode Water Eddy
A four-month glider mission was analyzed to assess turbulent dissipation in an anticyclonic eddy at the western boundary of the subtropical North Atlantic. The eddy (radius ≈ 60 km) had a core of low potential vorticity between 100–450 m, with maximum radi ...
2020Geometric deep learning for medium-range weather prediction
Medium-range numerical weather prediction (NWP) is crucial to human activities. Reliable weather forecasts allow better resource management and are essential for disaster preparation. Modern NWP models provide accurate medium-range forecasts, but they requ ...
