Voyager file of PM-2.5 Mass Data, 1/99-3/00, as Extracted from AIRS on 7/14/00. Also gif animation of 3rd day mass concentrations in Northeastern US
PM10 and PM2.5 data collected every 6th day and hourly PM2.5 data collected using TEOM samplers for three Connecticut sites: Bridgeport, New Haven, and Westport, during 1998 and 1999.

Files of various US PM and gaseous data, extracted from AIRS for February,1998, are posted in several formats here to facilitate a collaborative US/Canada analysis of an unusual, large-scale stagnation event in the Northeastern US and Eastern Canada, centered on about 2/10/98. The episode is generally described in previous summaries for the NE US and for Quebec Province and is illustrated by several North American maps (mostly Canadian data, so far) which were recently prepared by Environment Canada.
North American Integrated Ozone Daily Maximum Data Set
Daily maximum ozone for the entire U.S. (1415 sites) and Canada (167 sites) from 1986 - 1996. The data set was created by integrating ozone data from 7 networks including data from EPA's Aerometric Information Retrieval System (AIRS), Canada's National Air Pollution Surveillance Network (NAPS), and CASTNet. This data set is an update of the OTAG daily maximum ozone data set
The purpose of this page is to provide an up-to-date summary of this summer's ozone exceedances in the northeast U.S. and other parts of the country. Data from the eight NESCAUM states are obtained from the Ozone Mapping System and confirmed with each agency prior to posting on this web site. Data from the seven MARAMA states (excluding NJ) and the District of Columbia are obtained from weekly updates provided by MARAMA. These data are provided directly to MARAMA by each agency. Data outside these regions are obtained from a variety of publicly-accessible Internet sources
These data are gathered quickly and from a variety of sources. The data have not been quality assured and are subject to change. The data should only be viewed as a general indication of region-wide exceedances this summer. Inaccuracies should be brought to the attention of Paul Miller (pmiller@nescaum.org).

VT DEC conducted long-term (climatological) back-trajectory analyses for 23 ozone monitoring sites in the Eastern US for the OTAG Air Quality Analysis Workgroup. Some of the results are summarized here in the form of animations, which may be viewed on-line and/or downloaded for subsequent use in other applications. Access is also provided to more detailed technical reports describing methods, caveats, etc.
The data files in this archive contain results from the NEPART network, operated by the Northeast States for Coordinated Air Use Management (NESCAUM). The 7 rural NEPART sites conducted IMPROVE-type Module A PM-2.5 sampling and filter analysis between 1988 and 1993. The zipped data files include raw data (3 samples/week) and monthly averages. Data formats include Voyager and the ASCII data files used for the Voyager compilation.
The data files included in this zip archive contain aerosol concentration and composition data from 1988-1995 for the IMPROVE network. Raw (daily) data are included, as well as monthly, quarterly and annual aggregations. Data formats include Voyager and the ASCII files used for Voyager compilation.
The file “estoz96v.zip” is a zipped Voyager file, ca. 1.38 mb. It was zipped using “pkzip.” The file size is ca. 5.77 mb unzipped. It was made from data in AIRS as of 4/22/97 for the period from 5/96 to 10/96. The file contains ozone concentration data and wind direction data from all AIRS sites in Virginia up the Atlantic coast through Maine, including all of the New England States. Submitted by Carol Bellizzi, U.S. EPA Region 2, for use in PAMS data analysis. (AIRS= EPA Aerometric Information Retrieval System).
This dataset contains measured PM10, PM2.5 and TSP for the contiguous U.S from 1985 - 95. The data were extracted from EPA's Aerometric Information Retrieval System (AIRS).
