In 1988, Crocker’s team installed IMPROVE’s aerosol samplers at the program’s first 20 sites, including Acadia, Big Bend, Hawaii Volcanoes and Yellowstone national parks. Since then, the team has outfitted approximately another 150 sites with its IMPROVE samplers.

With the program’s demonstrated success in visibility monitoring and steady advances in instrumentation and data analysis, it has been joined by a number of agencies and groups not affiliated with Class 1 areas. Of the nearly 170 currently active IMPROVE sites, about 60 are hosted by such groups, while the remainder are associated with Class 1 areas.

In the past five years, the program has expanded internationally as well, with the Crocker team installing IMPROVE aerosol samplers and providing training to groups in Canada and South Korea.

With its 25 years of experience designing, improving and refining core components of the IMPROVE program, Crocker holds a unique vantage point in the field of monitoring and analysis of airborne particles. Agencies or organizations interested in establishing airborne particle monitoring programs should contact Chuck McDade, principal investigator of the IMPROVE program.
