TL;DR

This paper introduces CAMP version 1.0, an integrated multi-phase chemistry model that simulates aerosol processes across modal, binned, and particle-resolved representations using consistent chemical mechanisms. It demonstrates consistent performance across all three aerosol frameworks and provides 3D Eulerian model outputs, enabling improved simulation of multiphase atmospheric chemistry with unified mechanisms across phase representations.

ABSTRACT

This dataset contains all the data for the results section in the study presented in the paper entitled "Chemistry Across Multiple Phases (CAMP) version 1.0: An integrated multi-phase chemistry mode" submitted to Geoscientific Model Development (GMD). In this paper, two sets of simulations were run to test CAMP with this results included here. This consists of (1) box model inputs and outputs presented in Section 4.2 for modal, binned and particle-resolved simulations to compare the application of identical chemical mechanisms to different aerosol representations and (2) the 3D Eulerian output presented in Section 4.3.

Motivation & Objective

• To develop a unified chemical mechanism applicable across multiple aerosol representation frameworks (modal, binned, particle-resolved).
• To enable consistent simulation of multiphase atmospheric chemistry by integrating the same mechanisms across different aerosol representations.
• To evaluate model performance and consistency across different aerosol representations using box model and 3D Eulerian simulations.
• To provide a comprehensive dataset of model inputs and outputs for validation and reproducibility in atmospheric chemistry research.
• To support future development of multi-phase chemistry models by establishing a benchmark framework with standardized outputs.

Proposed method

• Implementation of a common chemical mechanism across three aerosol representations: modal, binned, and particle-resolved.
• Use of box models to compare model behavior under identical chemical mechanisms but different aerosol representations.
• Application of the CAMP model in a 3D Eulerian framework to simulate atmospheric chemistry across spatial and temporal dimensions.
• Simulation of multiphase processes including gas-phase reactions, aqueous-phase chemistry, and heterogeneous reactions on aerosol surfaces.
• Generation of standardized input and output datasets for model evaluation and reproducibility.
• Validation of model consistency by comparing results across different aerosol representations under identical chemical mechanisms.
