The potential of drone observations to improve air quality predictions by 4D-Var [PDF]

Atmospheric Chemistry and Physics
Vertical profiles of atmospheric pollutants, acquired by uncrewed aerial vehicles (UAVs, known as drones), represent a new type of observation that can help to fill the existing observation gap in the planetary boundary layer (PBL). This article presents

Application of fuzzy c-means clustering for analysis of chemical ionization mass spectra: insights into the gas phase chemistry of NO₃-initiated oxidation of isoprene [PDF]

Atmospheric Measurement Techniques
Oxidation of volatile organic compounds (VOCs) can lead to the formation of secondary organic aerosol (SOA), a significant component of atmospheric fine particles, which can affect air quality, human health, and climate change.

Structure and Spectroscopy of Criegee Intermediates in Gas‐ and Aqueous Environments

Helvetica Chimica Acta, EarlyView.
ABSTRACT The dynamics and spectroscopy of the small (H2COO) and large (CH3CHOO) Criegee intermediates (CIs) in the gas phase, inside/on water droplets, on amorphous solid water (ASW) and in bulk water are investigated using validated energy functions.

Observational evidence reveals the significance of nocturnal chemistry in seasonal secondary organic aerosol formation

npj Climate and Atmospheric Science
Oxidized Organic Aerosol (OOA), a major component of fine atmospheric particles, impacts climate and human health. Previous experiments and atmospheric models emphasize the importance of nocturnal OOA formation from NO3· oxidation of biogenic VOCs.

Seasonal Variability of Precipitating Systems in Four Radar Domains of Northeast Brazil

International Journal of Climatology, EarlyView.
This study analyzes the climatology and evaluates how the physical aspects of precipitating systems are influenced by the dry and wet seasons in Northeast Brazil, highlighting seasonal variations in the frequency, size, intensity, and duration of these systems in the regions of Natal, Maceió, Petrolina, and Salvador.

User‐Relevant Climate Indices and Associated Uncertainties From Transient Convection‐Permitting Climate Model Projections

International Journal of Climatology, EarlyView.
A transient ensemble of convection‐permitting climate simulations is used to compute bias‐corrected user‐relevant climate indices for Germany under recent and future climate conditions, both considering high spatial resolution and uncertainty estimations. For high temperature indices, a clear increase is observed, for example, for hot days and tropical
