Research data supporting "Sources apportionment of Fine Particulate Matter in Delhi using Integrated Multi-Dataset Analysis"

PM2.5 samples were collected at two sites - the Indian Institute of Technology Delhi (IITD) and Indira Gandhi Delhi Technical University for Women (IGDTUW), during the winter (Jan-Feb), pre-monsoon (May-June) and post-monsoon (Oct-Nov) in 2018 as part of the ASAP-Delhi project. Positive Matrix Factorization (PMF) was applied to identify PM sources using a novel integrated multi-dataset approach, combining filter-based chemical composition (including organic markers), and high-time-resolution online measurements (Aerosol Chemical Speciation Monitor, Streaker, Aethalometer). The Excel files contain details on the sources identified using multi-dataset approach (PMF_classic, PMF_extended and High-res PMF) at two sites: the Indian Institute of Technology Delhi (IITD) and Indira Gandhi Delhi Technical University for Women (IGDTUW)
