Workshop on Opportunities to Improve the Representation of Clouds and Aerosols in Climate Models with National Collection Systems

The impact of aerosols on the atmosphere is widely acknowledged as one of the most significant and uncertain aspects of climate change projections. Although scientists know much about the general nature of the interactions between aerosols and clouds, the simulation of clouds and how they will respond to aerosol changes is a central challenge in climate modeling. At the request of the Intelligence Community, the National Academies is organizing a series of two workshops on this topic:

Unclassified workshop: June 24-25, 2015, to engage with Sackler and other uncleared participants to identify gaps in our capabilities, significant barriers and challenges, and potential opportunities for improvements.

Classified workshop: September 28-30, 2015, to discuss the usefulness of classified observing systems in advancing understanding of aerosol-cloud-precipitation interactions.

Such an improved understanding could lead to a more accurate representation of cloud and aerosols in climate models, reducing the uncertainty of climate projections. Unclassified and classified summaries of the workshops will be prepared by a designated rapporteur.

Premise: The current satellite systems and their available data streams do not provide adequate observations of aerosols, clouds, and precipitation to constrain our modeling of the relative impact of aerosols and their precursors on the climate and hydrologic systems on a global or regional scale.

  • Review current and planned, non-proprietary and unclassified, satellite observations capable of measuring the relationships between aerosols, clouds and precipitation.
  • Hear from invited experts on specific instrument-related topics, including
    • attributes, measurements, tolerances and calibration
    • current observing system capabilities (multiple instruments), and gaps in that system
    • next-generation instruments and systems
  • Identify opportunities available in the current and planned Global Earth Observing System of Systems (GEOSS), including the civilian space sector, for building a coherent system to address aerosol-cloud interactions and related questions. Identify also the limitations.

One of the most significant and uncertain aspects of climate change projections is the impact of aerosols on the climate system. Aerosols influence the climate indirectly by interacting with nearby clouds leading to small changes in cloud cover, thickness, and altitude, which significantly affect Earth's radiative balance. Advancements have been made in recent years on understanding the complex processes and atmospheric interactions involved when aerosols interact with surrounding clouds, but further progress has been hindered by limited observations.

The National Academies of Sciences, Engineering, and Medicine organized a workshop to discuss the usefulness of the classified observing systems in advancing understanding of cloud and aerosol interactions. Because these systems were not developed with weather and climate modeling as a primary mission objective, many participants said it is necessary for scientists to find creative ways to utilize the data. The data from these systems have the potential to be useful in advancing understanding of cloud and aerosol interactions. This publication summarizes the presentations and discussions from the workshop.
