PMF-AMS Analysis Guide

The PMF-AMS Analysis Guide provides documentation for the PMF Evaluation Tool (PET), an Igor Pro-based software package for applying Positive Matrix Factorization (PMF) to aerosol mass spectrometry (AMS) and related datasets. It describes the complete analysis workflow, including software installation, preparation of data and uncertainty matrices, configuration and execution of PMF analyses, and evaluation of the resulting factor profiles and time series. The guide also covers key analysis parameters, diagnostic tools for assessing solution quality and robustness (e.g., number of factors, FPEAK, SEED, and bootstrapping), comparison of PMF factors with external datasets, and practical guidance for interpreting results. In addition, it provides links to the PET software, reference datasets, and relevant methodological literature.
