[MIRA] A webinar reminder and a workshop announcement redux

Sun Jun 23 20:59:38 PDT 2024

Friends of MIRA,

Apologies for the extra post… The previous announcement was supposed to come with a powerpoint attachment that describes the potential workshop venues in Greece, which is now attached. The powerpoint describes the four potential venues mentioned in the survey (Kastri Domotel Athens, Royal Olympic Hotel, Amalia Hotel, and Nafplia Palace). A big thanks to Vassilis Amiridis and his team for researching these venues putting the powerpoint together.

A couple of announcements.

First, a friendly reminder of the Morphing MIRA webinar tomorrow at 21 UTC (Monday afternoon in North America, early Tuesday morning in other parts of the world). See Dr. Riemer’s abstract and bio below, and click on this link to join:

Second, we are in the early planning stages of a MIRA workshop that we will hold in Greece sometime in May/June of 2025. The workshop will focus on all of the MIRA topics described at https://science.larc.nasa.gov/mira-wg/topics/, and more. For example, we intend to include discussions about aerosol-cloud interactions as well as the harmonization of ground-based, sub-orbital, and space-based lidar measurements. The over-arching objectives of the workshop are to

  *   create an environment that facilitates interchange amongst aerosol scientists who are working in different topical areas,
  *   increase personal interchange amongst international participants, and
  *   encourage dialogue amongst scientists with varying levels of expertise.
We hope that you can help us size the event and focus the venue by filling out the very brief survey at https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdocs.google.com%2Fforms%2Fd%2Fe%2F1FAIpQLSf5CkiIA_F5hlbYAineVexac9zLHXR_WDNUfzhTnsIrlKE8ww%2Fviewform&data=05%7C02%7Cmira%40espo.nasa.gov%7C2c5914f56ca14cce477508dc9402358a%7C7005d45845be48ae8140d43da96dd17b%7C0%7C0%7C638547984463679221%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=zXe0dJ51gzmx2ZIsr2RAnLimoMmWq3VyRZDjfGLkiNM%3D&reserved=0<https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdocs.google.com%2Fforms%2Fd%2Fe%2F1FAIpQLSf5CkiIA_F5hlbYAineVexac9zLHXR_WDNUfzhTnsIrlKE8ww%2Fviewform&data=05%7C02%7Cmira%40espo.nasa.gov%7C2c5914f56ca14cce477508dc9402358a%7C7005d45845be48ae8140d43da96dd17b%7C0%7C0%7C638547984463679221%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=zXe0dJ51gzmx2ZIsr2RAnLimoMmWq3VyRZDjfGLkiNM%3D&reserved=0>.

Unraveling aerosol mixing state: Enhancing climate impact predictions through particle-resolved simulations

Abstract:
Calculations of the aerosol direct effect on climate heavily rely on simulated aerosol fields. However, the accuracy of these calculations is often compromised due to the uncertainties introduced by the model representation of aerosols. These uncertainties stem from assumptions about the diversity of particle composition within the aerosol population, referred to as the aerosol mixing state. In this presentation, we aim to address the impact of simplifying the aerosol diversity on the accuracy of our estimates of aerosol optical properties. To achieve this, we employ a particle-resolved aerosol model, which represents aerosols as individual computational particles. These particles evolve in size and composition as they undergo aging processes in the atmosphere. Unlike commonly used modal or sectional aerosol models, our approach avoids limitations associated with assumptions about particle composition within specific size ranges. By leveraging particle-scale simulations, we provide compelling evidence that accurately capturing the aerosol mixing state is crucial for predicting population-level quantities such as absorption enhancement or single scattering albedo. Our findings have significant implications for remote sensing retrievals and further enable the development of parameterizations for global-scale models. In conclusion, our work underscores the importance of accounting for aerosol mixing state in climate models, and we demonstrate how particle-scale simulations can enhance our understanding of aerosol behavior, paving the way for improved parameterizations and more accurate global-scale models.
