USTC‐PRM: A Parameterized Approach for Profile Retrieval of Aerosol and Trace Gases

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 18, 28 September 2025.
Abstract Profiles of aerosol and trace gases are crucial for assessing air pollution changes, identifying the high‐altitude transport of pollutants, and providing a foundation for tracing pollution sources. This study introduces the USTC Parameterized Retrieval Method (USTC‐PRM), an algorithm for retrieving profiles of aerosol extinction and trace gas ...

How Do Institutional Pressures Reshape the Association Between Corporate Sustainability Disclosure and Firm Value in Emerging Economies? The Moderating Role of the Audit Committee Function

Business Strategy and the Environment, Volume 34, Issue 6, Page 7253-7283, September 2025.
ABSTRACT This study examines the influence of normative (e.g., voluntary sustainability reporting guidelines) and coercive (e.g., mandatory corporate governance [CG] requirements) pressures on the relationship between corporate sustainability disclosure (CSD) and financial performance (FP), focusing on the moderating role of audit committee ...

LRP2 Expression in Melanoma Is Associated With a Transitory Cell State, Increased T Cell Infiltration, and Is Upregulated by IFNy Signaling

Pigment Cell &Melanoma Research, Volume 38, Issue 5, September 2025.
ABSTRACT Low density lipoprotein receptor‐related protein 2 (LRP2) is a 600 kilodalton multi‐ligand endocytic membrane receptor expressed in several cell types during fetal development, including neuroepithelial cells, and in select absorptive epithelial cells in the adult.

A laboratory characterisation of inorganic iodine emissions from the sea surface: dependence on oceanic variables and parameterisation for global modelling [PDF]

, 2014
Reactive iodine compounds play a significant role in the atmospheric chemistry of the oceanic boundary layer by influencing the oxidising capacity through catalytically removing O3 and altering the HOx and NOx balance.

Comprehensive Analysis of Bias in TEMPO NO2 Column Densities Through Pandora Observations

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 15, 16 August 2025.
Abstract Tropospheric Emissions: Monitoring of Pollution (TEMPO) is the first geostationary satellite instrument to monitor air pollutants across North America. This study uses Pandora observations to analyze the bias in TEMPO Level‐3 total column density of NO2 (TOTNO2) from August 2023 to December 2024.

MAX-DOAS detection of glyoxal during ICARTT 2004

Atmospheric Chemistry and Physics, 2007
The direct detection of glyoxal (CHOCHO), the smallest α-dicarbonyl, in the open atmosphere by active differential optical absorption spectroscopy (DOAS) has recently been demonstrated (Volkamer et al., 2005a) and triggered the very recent successful detection of CHOCHO from space (Kurosu et al., 2005; Wittrock et al., 2006; Beirle et al., 2006).

Satellite‐Based Analysis of CO2 Emissions From Global Cities: Regional, Economic, and Demographic Attributes

AGU Advances, Volume 6, Issue 4, August 2025.
Abstract Cities play a crucial role in reducing global greenhouse gas emissions. While activity‐based (“bottom up”) emission estimates are widely used for global cities, they often lack independent verification. In this study, we use remotely‐sensed CO2 observations from the Orbiting Carbon Observatory‐3 (OCO‐3) to “top‐down” estimate CO2 emissions for
