How Do Planetary Boundary Layer Schemes Perform in PM2.5‐O3 Composite Pollution in the Beijing‐Tianjin‐Hebei (BTH)? An In‐Depth Mechanism Analysis From the Underlying Code

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.
Abstract Parameterization schemes undergo continuous updates, with most refinements documented in code implementations, necessitating in‐depth code analysis for evaluation. Focusing on PM2.5‐O3 composite pollution in the Beijing‐Tianjin‐Hebei region, 10 planetary boundary layer (PBL) schemes were evaluated for their simulation performance.

Summertime impact of convective transport and lightning NO_x production over North America: modeling dependence on meteorological simulations [PDF]

Atmospheric Chemistry and Physics, 2009
Global-scale chemical transport model simulations indicate lightning NOx dominates upper tropospheric O3 production above Eastern North America during summertime but vary in their estimates.

Using Bayesian Model Averaging (BMA) to calibrate probabilistic surface temperature forecasts over Iran [PDF]

Annales Geophysicae, 2011
Using Bayesian Model Averaging (BMA), an attempt was made to obtain calibrated probabilistic numerical forecasts of 2-m temperature over Iran. The ensemble employs three limited area models (WRF, MM5 and HRM), with WRF used with five different ...

Turbulence‐Induced Non‐Monotonic Influence of Aerosols on Cloud Droplet Size Distribution

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Cloud droplet size distribution (DSD) is essential for quantifying the roles of clouds in earth system, including cloud albedo, precipitation formation, and cloud lifetime. The response of cloud droplet spectral relative dispersion (ε) to aerosol number concentration (Na) as well as the role of turbulence in this response are yet puzzling ...

A Generalized Sigma-Coordinate System for the MM5

Monthly Weather Review, 2003
Abstract A generalized sigma-coordinate system is presented that allows for a rapid vertical decay of small-scale topographic structures in the coordinate surfaces. Its properties are similar to the smooth-level vertical-coordinate system recently introduced by Schar et al., but it is designed for the coordinate definition used in the fifth-generation ...

Sensitivity analysis of the MM5 weather model using automatic differentiation [PDF]

Computers in Physics, 1996
We present a general method for using automatic differentiation to facilitate model sensitivity analysis. Automatic differentiation techniques augment, in a completely mechanical fashion, an existing code such that it also simultaneously and efficiently computes derivatives.

Unveiling Salt Tolerance Mechanisms in Plants: Integrating the KANMB Machine Learning Model With Metabolomic and Transcriptomic Analysis

Advanced Science, Volume 12, Issue 23, June 20, 2025.
Salt stress endangers coastal cereal crops, requiring resilient crop solutions. This study employs machine learning (KANMB) to analyze multi‐omics data from halophyte Spartina alterniflora, revealing 226 salt‐stress biomarkers and linking them to tolerance pathways. The MYB gene SaMYB35 regulates flavonoid biosynthesis under salinity.
