Physics‐Guided CNN‐LSTM Model With Multi‐Head Attention for Aerosol Optical Depth Prediction

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Accurate aerosol optical depth (AOD) prediction remains challenging due to complex aerosol‐radiation interactions and highly variable spatio‐temporal patterns. Three critical scientific issues motivate this work: understanding whether and how physical principles can enhance deep learning predictions, identifying which aerosol properties most ...

Application of CMAQ at a hemispheric scale for atmospheric mercury simulations [PDF]

, 2011
Abstract. Application of a regional model to study of fate and transport of a global pollutant such as mercury in the atmosphere can be challenging and improper usage of models may lead to questionable results. The difficulties in such application stem from the fact that regional models are usually used in relatively small domains and rely heavily on ...

How Will China's Surface Ozone Evolve Under Carbon Neutrality Target and Global Climate Warming?

Earth's Future, Volume 14, Issue 1, January 2026.
Abstract Surface ozone (O3) has complex relationships with its precursors and is also highly sensitive to meteorological variation and climate change. In China, ground‐level ozone pollution remains a persistent air quality concern despite decreasing concentrations of other air pollutants in recent years.

Preparation of GEOS-Chem Emissions from CMAQ

, 2021
This notebook takes SMOKE outputs, which are CMAQ-ready emissions and converts them for use in GEOS-Chem. The tutorial uses "gridded reports", which contain annual data. To make this operational, you instead repeat the process for each month.

LSTM‐Based Hybrid Deep Learning Models for Visibility Prediction: A Data‐Driven Approach

Advances in Meteorology, Volume 2026, Issue 1, 2026.
Accurate visibility prediction is crucial for aviation safety, transportation operations, and environmental monitoring. This study proposes a data‐driven forecasting framework based on long short‐term memory (LSTM) neural networks and their hybrid variants.

Investigation of NO_x emissions and NO_x-related chemistry in East Asia using CMAQ-predicted and GOME-derived NO₂ columns [PDF]

Atmospheric Chemistry and Physics, 2009
In this study, NO2 columns from the US EPA Models-3/CMAQ model simulations carried out using the 2001 ACE-ASIA (Asia Pacific Regional Aerosol Characterization Experiment) emission inventory over East Asia were compared with the GOME-derived NO2 columns ...

Constraining African Fire CO2 Emissions During 2015–2016 Using Satellite XCO2 Retrievals

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Fire CO2 emissions are a critical component of the global carbon cycle, yet their estimates remain highly uncertain. This study introduces a satellite‐constrained inversion framework that jointly optimizes fire emissions and net ecosystem exchange using OCO‐2 XCO2 retrievals.

Updates to the Noah Land Surface Model in WRF‐CMAQ to Improve Simulated Meteorology, Air Quality, and Deposition

Journal of Advances in Modeling Earth Systems, 2019
Regional, state, and local environmental regulatory agencies often use Eulerian models to investigate the potential impacts on pollutant deposition and air quality from changes in land use, anthropogenic and natural emissions, and climate.
