Timing the Sacred: A Multi‐Step Chronological Framework for the Llullaillaco Inca Burial

Archaeometry, EarlyView.
ABSTRACT Absolute radiocarbon dating offers high precision, but its application to historical contexts, such as the Inca civilization, requires a rigorous methodological approach. This research examines methods to enhance chronological accuracy through a case study of artifacts from the Llullaillaco Capacocha sacrifice.

Analysis of Air Pollution Trajectory Using the HYSPLIT Model

Journal of Engineering Science and Technology Management (JES-TM)
The growth of industrial activities has contributed significantly to the increase in air pollutant emissions, adversely affecting human health and environmental quality. Understanding the direction and potential dispersion of air pollutants is therefore a crucial aspect of air pollution control efforts, particularly for mitigating transboundary and ...

A Lagrangian Time‐Series Machine Learning Framework for Predicting Concentrations and Exploring Drivers of Atmospheric Aerosols: Model Development and Application to Cloud Condensation Nuclei in Marine Boundary Layer

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.
Abstract Atmospheric aerosols play critical roles in climate and air quality. Accurately assessing their environmental impacts requires understanding aerosol abundance, distribution, and the key factors and processes that control them. Although machine learning is increasingly used in predicting aerosol concentrations, its application in exploring ...

Application of HYSPLIT and WRF/Chem Models to Investigate the Dust Storm Episodes

, 2016
Background: Long-range transport of dust aerosol has intense impacts on theatmospheric environment over wide areas. Methods: The annual and seasonal changes inmeteorological parameters associated with the occurrence of dust storms were studied. Thefeatures of an intense dust storm and its transport characteristics were studied during June 7thto June ...

Inline Coupling of WRF–HYSPLIT: Model Development and Evaluation Using Tracer Experiments

Journal of Applied Meteorology and Climatology, 2015
AbstractThe Hybrid Single-Particle Lagrangian Integrated Trajectory model (HYSPLIT), a Lagrangian dispersion model, has been coupled (inline) to the the Weather Research and Forecasting (WRF) Model meteorological model in such a way that the HYSPLIT calculation is run as part of the WRF-ARW prediction calculation.

Errors in top-down estimates of emissions using a known source [PDF]

Atmospheric Chemistry and Physics, 2020
Air pollutant emissions estimates by top-down methods are subject to a variety of errors and uncertainties. This work uses a known source, a coal-fired power plant, to explore those errors.

The Altitude Effect of Stable Isotopes in Rivers Over the Tibetan Plateau

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The altitude effect of stable isotopes in river water is key to paleoelevation reconstruction, yet remains poorly quantified at regional scales due to monitoring challenges. This study compiled river water isotope data across the Tibetan Plateau and used a decision‐tree‐based random forest model to simulate high‐resolution δ18O patterns.
