IMPROVE Data and Metadata - Express Tools

The tools below provide access to the full collection of data and metadata from the Interagency Monitoring of Protected Visual Environments (IMPROVE) program. The IMPROVE program monitors pollutants and generates metrics to identify sources and causes of regional haze at all Class 1 Areas in the U.S. There are several distinct subsets of IMPROVE data, including raw aerosol measurements, calculated variables, light extinction parameters, and Regional Haze metrics for the haziest, most impaired, and clearest visibility days.
