IMPROVE Graphic and
Image Viewer
The 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. |
