Measurements and Analysis Products from Baselining the Indirect Effect by Improving Quantification of Sea Spray and Marine Sources at Ascension Island during LASIC

About this Collection

This collection provides codes and data that are described in the publication "Aerosol-Limited Effects on Cloud Condensation Nuclei in Clean Conditions in the Tropical South Atlantic Boundary Layer during LASIC." Measurements used in this publication were collected during the Department of Energy Atmospheric Radiation Measurement Layered Atlantic Smoke Interactions with Clouds (LASIC) campaign from June 2016 to October 2017. Fitting parameters of the aerosol size distribution were retrieved using an automated lognormal fitting procedure and an algorithm that combines nephelometer scattering and UHSAS mass size distributions by applying a Mie inversion (Dedrick et al., 2022). The classification of clean and smoky periods were found using a combination of physical and chemical tracers of continental influence. These datasets are provided as text files at 2-hourly resolution during the LASIC campaign. The retrieval codes are provided as MATLAB scripts. View this collection on the contributor's website.
