Climate & Atmosphere Processes

Climate and Atmosphere Processes scientists study the processes that drive variability and change in the atmosphere and broader climate system. They develop modeling tools to predict these changes at different time and space scales.

Programs

Program

Climate Modeling

This program aims to develop global process-resolving models to help quantify the roles of climate feedbacks in anthropogenic climate change. Abrupt and extreme climate changes from anthropogenic warming pose some of the greatest risks to society and the environment. Understanding of the complex interactions involved with feedbacks is critical.

Program

Atmospheric Systems Research

This program seeks to improve understanding of surface atmosphere exchanges of carbon, water, and energy, and their roles in ecosystem-climate interactions, as well as to quantify the convective transport of CO2, water, mass, and momentum.

Background

The Climate and Atmosphere Processes (CAP) Program Domain was initiated in 2015 and is one of four Program Domains within the Climate and Ecosystem Sciences Division. Projects and programs within the CAP program domain use a combination of theory, models, and observations to develop our understanding of the processes that drive variability and long-term change in the atmosphere. Core capabilities in the CAP program domain include:

  • expertise in the physics and statistics of climate extremes;
  • models and parameterizations for simulating atmospheric phenomena across a wide range of scales: from convective (1 km) to global (25,000 km);
  • expertise, models, and theoretical understanding of the propagation of light and thermal radiation in the atmosphere; and
  • theoretical and observational understanding of the processes that govern cloud behavior.

Vision and Mission

Vision: A comprehensive theoretical and predictive understanding of the processes that drive variability and change in the atmosphere and broader climate system

Mission: To develop foundational knowledge and capabilities needed to understand and predict variability and change in the atmosphere and broader climate system
