From Nevada to Jakarta, the work of DRI scientists often has long-lasting impacts in far-off places. This fall, scientists Alan Gertler, Ph.D., John Watson, Ph.D., Judith Chow, Sc.D., Sarath Guttikunda, Ph.D., and Ricky Tropp, Ph.D., received word that air quality monitoring guidelines and reports from a decade-old project in Indonesia had served a beneficial new purpose: providing key evidence in an important court decision that will require stricter air quality standards in the City of Jakarta.

The City of Jakarta is home to 10 million people, and severely polluted by sources that include vehicle emissions, factories, and coal-fired power plants. Additionally, burning of rainforest to create space for palm oil plantations in the countryside causes air pollution that extends into neighboring countries such as Singapore, Vietnam, Laos, and Thailand.

In 2011, this DRI team began a multi-year project funded by the U.S. Environmental Protection Agency to develop an urban air quality management program for Jakarta. The first phase of the project consisted of an emissions inventory, an assessment of health impacts of air pollution, development of pollution abatement strategies, upgrading the air quality measurement and management program, training in-country personnel in air quality management, development of an air quality index, and more.

Unfortunately, the second phase of the project, which would have consisted of developing control strategies for emissions reduction and providing air quality information to the public, was never funded.

“Although Phase II of the project was never funded, we did as much as we could with the funding that we had for Phase I,” said Gertler, Principal Investigator and Project Manager for the Jakarta project. “We worked on the project for a number of years and were able to make great progress toward helping stakeholders in Jakarta develop better air quality management capabilities.”

The DRI team completed their work on this project in 2017, but the air pollution problems in Jakarta continued. In 2019, a group of 32 Indonesian citizens decided to take action and filed a lawsuit against Indonesian President Joko Widodo and other top officials for neglecting the citizens’ rights to clean air.

As evidence, the prosecution requested the use of a number of data files and records from DRI’s project. Gertler and Watson were happy to comply – and in September, the court ruled in the Indonesian citizens’ favor, ordering the officials to tighten national air quality standards and fulfill the rights of citizens to a good and healthy environment.

“I’m really glad that someone was able to make use of the work that we did, and that they were successful at winning their case,” said Gertler. “Let’s hope they can make some progress toward cleaner air in Jakarta.”

DRI Air Quality Experts Awarded Prestigious Haagen-Smit Prize

DRI Air Quality Experts Awarded Prestigious Haagen-Smit Prize

April 30, 2020 (RENO) – Drs. Judith Chow and John Watson, research professors in the Division of Atmospheric Sciences at the Desert Research Institute in Reno, were awarded Elsevier Publisher’s 2019 Haagen-Smit Prize for outstanding paper published in the journal Atmospheric Environment.

Awarded annually, the Haagen-Smit Prize recognizes two outstanding papers out of the nearly 24,000 articles published in Atmospheric Environment since 2001. The 2019 Prize went to Chow, Watson, and their colleagues for their 1993 paper, “The DRI thermal/optical reflectance carbon analysis system: Description, evaluation and applications in U.S. air quality studies,” which has received more than 925 citations. It is the 12th most cited article in Atmospheric Environment since the journal’s inception.

“This paper has had a major influence on the practice of atmospheric science as evidenced by its very high number of citations,” wrote the Haagen-Smit Prize Committee.

The winning paper by Chow, Watson, and their DRI colleagues describes and evaluates instrumentation and methodology developed at DRI. The DRI Carbon Analyzer instrument and their analytical method was subsequently commercialized and adopted in air quality networks in the United States and other countries, including Canada and China. The resulting measurements have been used to determine the contributions to air pollution from sources like domestic cooking and heating, engine exhaust, wildfires, and other emitters, all of which affect human health, visibility, material soiling, and climate.

“We greatly appreciate this recognition for all of the contributing DRI faculty and staff, including Lyle Pritchett, Cliff Frazier, Rick Purcell, and especially our former Executive Director, the late Bill Pierson,” said Chow. “It illustrates the importance of the team efforts that distinguishes DRI.”

Dr. Ari Haagen-Smit was a pioneering air quality scientist who discovered and elucidated the origins of photochemical smog in southern California. He was a colleague of Dr. Frits Went at the California Institute of Technology, who later joined the DRI faculty and is the namesake of DRI’s Frits Went laboratory. Dr. Went developed methods to measure organic emissions from agricultural crops that Dr. Hagen-Smit applied to the engine exhaust emissions that created the smog.

This award is distinct from the California Air Resources Board’s (ARB) Haagen-Smit Clean Air Awards, often termed the “Noble Prize” of air quality science and policy. Dr. Haagen-Smit was the first ARB chairperson. Dr. Chow received this honor in 2011, and the 2018 award was bestowed on Dr. Watson.

At DRI, Chow leads Environmental Analysis Facility, where she, Watson, and her colleagues develop and apply advanced analytical methods to characterize air pollutants, identify sources and their effects on health, climate, visibility, ecosystems, and cultural artifacts.
