[Apologies if already posted. MCB people: any reactions?] This study does not explicitly mention SRM but it seems more than tangentially related to MCB.
Abstract: https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1029/2019GL084700 Ships often burn heavy fuel oil, typically creating large amounts of particulate pollution, which is known to modify cloud properties. This creates linear cloud formations, known as shiptracks. In this work, we investigate how the occurrence and properties of shiptracks are related to the particulate emissions from individual ships. We show that the introduction of regulation on ship fuel has already produced a dramatic effect on cloud properties, with shiptracks almost disappearing completely in regions where fuel is regulated. With this new information about the particulates produced by specific ships, we also show that many shiptracks are likely undetected by current identification methods. This study also provides a pathway towards measuring ship emissions using satellite data. Key points Ship fuel sulphate content controls have already had a significant impact on shiptracks Almost half of shiptracks may be undetected by current methods A potential method for retrieving ship emissions using cloud properties is demonstrated Press summary: https://www.sciencedaily.com/releases/2019/11/191105104420.htm -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
