The effects of atmosphere conditions on gamma-ray astronomy [PDF]

, 2005
The High Energetic Stereoscopic System (H.E.S.S.) experiment is an array of imaging atmospheric Cherenkov (IAC) telescopes of the next generation, with enlarged mirrors and advanced detector electronics compared to its predecessors.

Global Ozone Reduction Driven by Dust‐Catalyzed Halogen Chemistry

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract Tropospheric ozone (O3) influences climate and poses risks to human health and crop productivity. Its distribution is shaped by complex interactions between chemical production, transport, and loss processes, including reactions with naturally occurring halogens.

A Sensitivity Analysis of Flick‐AccuRT, a Coupled Ocean‐Atmosphere Radiative Transfer Model and Input Module

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Radiative transfer (RT) models typically solve the radiative transfer equation separately in either the atmosphere or the ocean, limiting accuracy across the atmosphere‐ocean interface. Here, we employ a coupled scalar discrete ordinate RT model to examine methods for the input of measured inherent optical properties (IOPs) of oceanic ...

The LASSO‐CACTI Library of Deep Convection Simulations for Córdoba, Argentina: Overview of Mesoscale and Large‐Eddy Simulations

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract The U.S. Department of Energy Atmospheric Radiation Measurement (ARM) User Facility recently released ensembles of high‐resolution atmospheric simulations of deep convection to complement ARM's measurements. These simulations are from the Large‐Eddy Simulation (LES) ARM Symbiotic Simulation and Observation (LASSO) activity and are for 20 case ...

Intercomparison of Global Solar Induced Chlorophyl Fluorescence Products

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Satellite observations of Sun‐Induced Chlorophyll Fluorescence (SIF) provide a powerful means to assess terrestrial photosynthesis at regional to global scales, yet major SIF products differ in retrieval strategy, radiometric stability, and sensitivity to environmental conditions.

Probing star formation and radio activity using faint galaxy redshift surveys [PDF]

, 2008
In this thesis, we study the evolution of radio luminosity functions (RLF) for AGN and star forming galaxies (SFG), the colour-magnitude distributions of radio and X-ray sources at redshift z ~1, the star formation rate density in dwarf galaxies at z ~1 ...

Biases and Uncertainties in Radiosonde‐Based Precipitable Water Vapor

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Precipitable water vapor (PWV) plays an important role in weather and climate phenomena. Accurate PWV measurements based on radiosonde observations are essential for assessing remote‐sensing measurements and long‐term trends. This study examines the performance of PWV algorithms, including their intrinsic biases and their sensitivity to ...

Morphological fingerprints of forbush decreases and their relation to geomagnetic storm severity

Contiene gráficosForbush decreases (FDs) are transient depressions in the galactic cosmic-ray flux observed by global neutron-monitor networks and are commonly associated with interplanetary disturbances driven by coronal mass ejections and related ...

Planetary system and star formation science with non-redundant masking on JWST

, 2016
Non-redundant masking (NRM) is a high contrast high resolution technique that is relevant for future space missions dedicated to either general astrophysics or extrasolar planetary astronomy.
