Please join RMSS-AWMA for our next virtual lunch meeting, where their topic will be “Air Quality – Bringing Research into Decision Making.”

The meeting will be held online via Microsoft Teams, from 12PM-1PM, on Wednesday, March 23rd.

If you plan to attend this meeting, please RSVP to Sergio Guerra (sguerra@braunintertec.com ).


According to the World Health Organization (WHO), 91% of the world population lives in areas where air pollution exceeds international guideline limits, and every year approximately 4.2 million people die prematurely from outdoor air pollution. Air pollution is a highly complex societal and scientific problem, and to address and manage the problem it is important to understand the driving factors behind elevated pollution levels and how they might change in the future as our economy and our climate change. In this presentation we will provide a few examples of our research activities ranging from a major field experiment over the Colorado Front Range to air quality forecasting for the U.S. and India to using ultra-high-resolution modeling for the evaluation of emission estimation methods. The one aspect all these projects have in common is that they are targeted to support stakeholders and the public in making informed decisions on managing the risk of air pollution.


Gabriele (Gabi) Pfister received both her master’s degree in geophysics and meteorology (1997) and her doctorate in geophysics (2000) at the Karl-Franzens University in Graz, Austria. After a postdoc at the National Institute of Water and Atmospheric Research (NIWA) in New Zealand, she came to NCAR in 2002 under an Austrian Erwin Schroedinger Fellowship. Gabi has remained at NCAR and is now a Senior Scientist and also serves as Deputy Director for the NCAR Atmospheric Chemistry Observations and Modeling Laboratory. Gabi’s research revolves around the field of atmospheric chemistry and air quality. She both develops and applies regional and global air quality models, and she has also used satellite retrievals of atmospheric composition and observations from field campaigns to successfully integrate modeling and measurements in her research. One of her most notable achievements has been the co-lead of the Front Range Photochemistry Experiment (FRAPPÉ), a major and successful field campaign along the Colorado Front Range in July-August 2014 with a focus on studying summertime ozone pollution.

Rajesh Kumar received his master’s degree in physics from Kurukshetra University, India and his doctorate degree in Earth Science from the University of Hamburg, Germany. He came to NCAR as a postdoctoral fellow in 2013 and stayed at NCAR after his postdoctoral fellowship. He is currently a Project Scientist III in the Research Applications Laboratory (RAL) of NCAR. Rajesh’s research focuses on air quality, which is one of the most important socioeconomic and environmental concerns around the world today. He synergistically integrates ground- and satellite-based air quality monitoring with atmospheric composition and modeling capabilities to address a number of air quality issues including transport and transformation of air pollution, the relative importance of local and foreign emissions, deterministic and probabilistic air quality predictions, aerosol-climate interactions, heterogeneous atmospheric chemistry, chemistry-climate interactions, projection of future air quality, and impact of air quality for public health and food security. One of his most notable achievements has been the development of an operational air quality forecasting system for New Delhi that has been helping the decision-makers cut peak pollution since 2018.
