VIEWS Graphical
Analysis 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 graphic viewer allows
the interactive browsing of the graphical results from the IMPROVE data
analyses. 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. This will be
replaced by the first VIEWS Annual Data Summary, due this fall. |

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. |
