Rethinking reactive halogen budgets in the midlatitude lower stratosphere [PDF]

open access: yes, 1999
Current stratospheric models have difficulties in fully explaining the observed midlatitude ozone depletion in the lowermost stratosphere, particularly near the tropopause.

Convective injection and photochemical decay of peroxides in the tropical upper troposphere: Methyl iodide as a tracer of marine convection [PDF]

open access: yes, 1999
The convective injection and subsequent fate of the peroxides H2O2 and CH3OOH in the upper troposphere is investigated using aircraft observations from the NASA Pacific Exploratory Mission-Tropics A (PEM-Tropics A) over the South Pacific up to 12 km ...

Photochemical production of ozone in the upper troposphere in association with cumulus convection over Indonesia [PDF]

open access: yes, 2002
The Biomass Burning and Lightning Experiment phase A (BIBLE-A) aircraft observation campaign was conducted from 24 September to 10 October 1998, during a La Niña period.

Considerations on the dynamics of a cold spell over Greece

open access: yesMeteorologische Zeitschrift, 1995
A cold spell was observed in March 1987 over Greece, which was characterised by extremely low temperatures and heavy snowfall. The dynamic and thermodynamic characteristics of this rather unusual event are investigated using ECMWF analyses.

Investigation of the β-pinene photooxidation by OH in the atmosphere simulation chamber SAPHIR [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
Besides isoprene, monoterpenes are the non-methane volatile organic compounds (VOCs) with the highest global emission rates. Due to their high reactivity towards OH, monoterpenes can dominate the radical chemistry of the atmosphere in forested areas ...

Photochemistry in the arctic free troposphere: NOx budget and the role of odd nitrogen reservoir recycling [PDF]

open access: yes, 2003
The budget of nitrogen oxides (NOx) in the arctic free troposphere is calculated with a constrained photochemical box model using aircraft observations from the Tropospheric O3 Production about the Spring Equinox (TOPSE) campaign between February and May.

MieAI: a neural network for calculating optical properties of internally mixed aerosol in atmospheric models

open access: yesnpj Climate and Atmospheric Science
Aerosols influence weather and climate by interacting with radiation through absorption and scattering. These effects heavily rely on the optical properties of aerosols, which are mainly governed by attributes such as morphology, size distribution, and ...

Use of wind profiler in severe weather monitoring

open access: yesMeteorologische Zeitschrift, 1998
A 1299 MHz wind profiler was acquired to monitor low level winds near the Hong Kong International Airport. It was found that the equipment was also capable of yielding quality data to support the study of severe weather.

Estimation of Atmospheric Path Delays in TerraSAR-X Data using Models vs. Measurements

open access: yesSensors, 2008
Spaceborne synthetic aperture radar (SAR) measurements of the Earth’s surface depend on electromagnetic waves that are subject to atmospheric path delays, in turn affecting geolocation accuracy.

The vertical profile of recent tropical temperature trends: Persistent model biases in the context of internal variability

open access: yesEnvironmental Research Letters, 2020
Tropospheric and stratospheric tropical temperature trends in recent decades have been notoriously hard to simulate using climate models, particularly in the upper troposphere.
