Introduction: A Scientist at the Center of Atmospheric Uncertainty
Understanding how aerosols and clouds influence Earth’s climate remains one of the most complex challenges in atmospheric science. These microscopic particles and dynamic cloud systems play an outsized role in regulating how much solar energy the planet absorbs or reflects back into space. At NASA, one of the scientists working directly at the heart of this challenge is Dr. Ed Nowottnick. As Program Manager of the Radiation Sciences Program within NASA’s Earth Science Division, Nowottnick oversees research efforts aimed at reducing uncertainties that continue to limit climate prediction accuracy. His career spans modeling, satellite instrumentation, airborne field campaigns, and mission leadership—placing him among the key figures shaping how NASA observes and interprets Earth’s atmosphere.
Professional Role at NASA Headquarters
Since March 2025, Dr. Nowottnick has served as the program scientist for the Radiation Sciences Program for the Atmosphere under NASA’s Research and Analysis Program. In this role, his mandate is both technical and strategic. He coordinates research priorities that focus on aerosols, clouds, and the processes governing their formation, interaction, and lifespan. These factors collectively determine the atmospheric radiation budget, a core variable in climate science. His position places him at NASA Headquarters, where scientific insight must translate into mission planning, funding direction, and long-term observational strategy.
Focus on Aerosols and Cloud Interactions
Aerosols and clouds are notoriously difficult to model because of their variability across space and time. Dr. Nowottnick’s work specifically targets the reduction of uncertainty surrounding these components. His efforts emphasize how aerosols influence cloud properties, how clouds modify radiative transfer, and how both evolve under changing environmental conditions. These interactions are among the largest contributors to uncertainty in climate projections, making his focus not only relevant but critical for future climate assessments.
Leadership in Earth Observation Missions
Beyond program management, Dr. Nowottnick holds several mission-level leadership roles. He is currently the NASA Program Scientist for the Multi-Angle Imager for Aerosols (MAIA) and Luce missions. These missions are designed to improve the characterization of aerosol properties and their impacts on air quality and climate. In parallel, he serves as Deputy Program Scientist for the Plankton, Aerosol, Cloud, ocean Ecology (PACE) mission and the Polar Radiant Energy in the Far-Infrared Experiment (PREFIRE). Each of these missions contributes unique observational capabilities that together form a more complete picture of Earth’s coupled atmosphere–ocean system.
Experience at NASA Goddard Space Flight Center
Prior to his current role, Dr. Nowottnick spent 15 years at NASA Goddard Space Flight Center, including five years as a civil servant. During this period, he was deeply involved in global aerosol modeling, airborne observation campaigns, and the development of algorithms for spaceborne atmospheric lidar systems. This combination of modeling and observational expertise allowed him to bridge the gap between theoretical understanding and real-world measurements.
Contributions to Aerosol Modeling and GEOS
One of Dr. Nowottnick’s significant contributions was the development of aerosol lifecycle capabilities within NASA’s Goddard Earth Observing System (GEOS) model. This work enhanced the ability of GEOS to simulate how aerosols form, evolve, and are removed from the atmosphere. Such improvements are essential for integrating satellite observations with predictive models, enabling more accurate assessments of aerosol impacts on climate and air quality.
Role in the CATS Mission on the ISS
Following his modeling work, Dr. Nowottnick became the aerosol algorithm lead for the Cloud Aerosol Transport System (CATS), which operated aboard the International Space Station from 2015 to 2017. CATS provided valuable lidar measurements of aerosols and clouds, offering new insights into their vertical distribution. His leadership in algorithm development ensured that the data collected could be reliably interpreted by the scientific community.
Instrument Science and ALICAT
After CATS, Dr. Nowottnick served as Instrument Scientist for the Atmospheric Lidar Instrument for Clouds and Aerosol Transport (ALICAT), planned for NASA’s Atmosphere Observing System mission. In this role, he contributed to instrument design and scientific requirements, ensuring that future lidar observations would address existing knowledge gaps in aerosol and cloud transport processes.
Extensive Field Campaign Participation
Dr. Nowottnick has been involved in numerous NASA field campaigns, many of which relied on high-altitude and long-range research aircraft. These include missions using the NASA ER-2, DC-8, and Gulfstream platforms. Campaigns such as GOES-R calibration and validation, FIREX-AQ, CAMP2Ex, IMPACTS, and CPEX-AW provided in situ and remote sensing data critical for validating satellite observations and improving models.
Leadership in CPEX-CV
Among his field leadership roles, Dr. Nowottnick served as Project Scientist for the Convective Processes Experiment – Cabo Verde (CPEX-CV). This campaign focused on understanding convective systems over the tropical Atlantic, an area influential in global circulation and weather patterns. His leadership ensured that scientific objectives were tightly aligned with observational strategy.
Academic Background and Training
Dr. Nowottnick’s academic foundation is rooted in atmospheric science. He earned his Bachelor of Science in Physical Sciences in 2005, followed by a Master of Science in Atmospheric and Ocean Sciences in 2011, and a Ph.D. in Atmospheric and Oceanic Sciences from the University of Maryland, College Park. This consistent academic trajectory reflects a long-term commitment to understanding Earth’s atmosphere from both physical and dynamical perspectives.
NASA Postdoctoral Fellowship
Following his doctoral studies, Dr. Nowottnick was a NASA Postdoctoral Program Fellow from 2011 to 2014. This period allowed him to deepen his research expertise while contributing to NASA’s scientific objectives. The fellowship also positioned him for long-term leadership roles within the agency.
Personal Interests Beyond Science
Outside of his professional responsibilities, Dr. Nowottnick values time with his family and enjoys outdoor activities. He also has interests in cooking and baseball, reflecting a balanced life beyond the demands of scientific leadership. These personal dimensions underscore the human element behind high-level research roles.

What Undercode Say: Scientific Leadership in an Era of Climate Complexity
Dr. Ed Nowottnick’s career reflects a broader trend within NASA toward integrated Earth system science. His work sits at the intersection of modeling, observation, and mission design, a space where scientific uncertainty is both a challenge and an opportunity. Aerosols and clouds remain among the least understood components of the climate system, and leadership in this area requires not only technical expertise but also the ability to coordinate across disciplines and institutions.
From Undercode’s perspective, Nowottnick’s trajectory illustrates how modern atmospheric science depends on long-term investment in both people and platforms. His progression from model development to instrument science and program management highlights the value of scientists who understand the full lifecycle of data—from collection to interpretation.
The emphasis on multi-angle imaging, lidar, and far-infrared measurements signals a strategic shift toward observing atmospheric processes in greater detail and across multiple spectral domains. These approaches are essential for resolving ambiguities that have persisted for decades in climate modeling.
Moreover, his extensive involvement in field campaigns underscores the continuing importance of in situ validation. Satellites alone cannot resolve all uncertainties; coordinated aircraft measurements remain indispensable.
Undercode also notes that leadership roles like Nowottnick’s increasingly require balancing scientific rigor with administrative responsibility. Managing programs, missions, and interdisciplinary teams is now as critical as publishing research.
In this context, Dr. Nowottnick represents a new generation of NASA scientists—equally comfortable with equations, instruments, and organizational strategy. His work contributes not only to improved climate predictions but also to the institutional knowledge that will guide future Earth science missions.
