Natural Haze Levels Sensitivity: Assessment of Refinements to Estimates of Natural Conditions
The Haze Sensitivity Report (PDF) presents an extensive analysis of how particulate component concentrations under natural conditions are being currently estimated and how improvements might be made in those estimates when appropriate. The process used to determine the needed rate of reduction in haze from current measured conditions to estimated natural conditions in 2064 is thoroughly reviewed. The report is accompanied by a Sensitivity Calculator (XLS) that enables the reader to explore the impacts of user-selected changes in the concentrations of the various components of the aerosol to the slopes of the uniform rate of progress lines in each zone.
