IMPROVE Graphic and Image Viewer

IMPROVE Graphic and Image ViewerThe IMPROVE Monitoring program deploys aerosol samplers to measure speciated fine aerosols and PM10 mass. In addition, transmissometers, nephelometers and cameras are deployed to measure light extinction and scattering respectively, as well as automatic camera systems to measure the “scene”. These measurements are used in a number of routine and novel data analyses to establish the current visibility conditions, track the changes in visibility and determine the causal mechanism for the visibility impairment in the National Parks and Wilderness Areas. These analysis results are gathered together and summarized approximately every three years in IMPROVE data analysis reports.

This IMPROVE graphic viewer allows the interactive browsing of the graphical results from the IMPROVE data analyses as well as the metadata associated with each monitoring site and network. The viewer provides spatial, temporal, variable, and frequency views of the data. These view are linked together allowing the browsing of the data in its proper multi-dimensional context.

Note: All calculations were performed using the NPS/CIRA methodologies. It is anticipated that the EPA methodology will be different and these figures will be updated after the EPA methods are finalized.

IMPROVE Monitoring Site Metadata - Detailed information about the improve monitoring sites including location, sampling equipment and history of changes at the monitoring site.

Diurnal Cycle - The diurnal cycle for light scattering and extinction data as well as relative humidity and temperature. These diurnal cycles are from all sites with transmissometer or nephelometers monitors and are for the entire data record at each site.

Spatial and Seasonal Patterns - The annual spatial pattern of PM2.5, light extinction and the contributions of the major aerosol types. In addition, seasonal bar charts of the PM2.5 and light extinction and the relative and absolute contributions of the major aerosol types. Last, frequency distributions of all aggregated values are available.

Long-Term Trends - The long term trends (1988 - 1998) of fine mass and its major aerosol types and light extinction and the contribution of major aerosol types to light scattering for each IMPROVE monitoring site with data since 1988.
