LADCO employees are motivated by difficult technical problems, and by improving public health and the environment.
LADCO is staffed by atmospheric scientists with expertise in modeling, monitoring, and analysis of air pollution. We strive to be the primary hub of technical information on air quality and air pollution modeling for the states and stakeholders in our region.
