People Involved in MILAGRO

More than 300 scientists from over 60 universities and research institutions in the United States, Mexico, and several other nations participated in the MILAGRO field campaign. The focus of the fieldwork was air pollution in Mexico City, one of the world’s largest cities with a population of 22 million people. Teachers were also involved in the project and shared their field science experience through Postcards from the Field.

The scientists’ roles are many and varied during field campaigns. So, too, are the tools and instruments that are used. The MILAGRO campaign was actually composed of four large science projects, each with many groups of scientists responsible for specific areas of research. Together, their work aimed at broading our knowledge of the transport and life cycle of air pollution.

Before the actual field campaign began, the various project scientists worked together to design, organize, and prepare for their mission for nearly two years to ensure that all of MILAGRO’s science objectives would be met. Similarly, their work now continues long after the field campaign is over. The scientists must review and process the data collected to determine what has been learned.

The best way to learn about the people involved in science field work, however, is from the scientists themselves and from the teachers working side-by-side with them. The links below will introduce you to a handful of MILAGRO scientists and teachers. Through their stories, we hope to bring science to life and illustrate the important being done in the area of air quality.
