Air Quality Data (1980-1999) from the California Air Resources Board
Listed in NASA Earthdata CMR
The California Air Resources Board has available two CD-ROMs (CDs) with 20 years of air quality data.
Description
Both CDs contain essentially the same air quality data, but provide these data in different formats. The CDs contain 20 years of Criteria Pollutant air quality data (1980-1999), 10 years of Toxics air quality data (1990-1999), 12 years of dichotomous sampler (Dichot) data (1988-1999), and 6 years of non-methane organic compound (NMOC) data (1994-1999).
These CDs are updates to the air quality data CDs released before 2001. One of the many new additions to the new CDs is a hyperlinked version of supporting documents. The first CD contains data that are displayed graphically using Voyager (a program contained on the CD, which displays data on maps and as time series graphs).

This CD also includes annual data summaries in table format, which can be viewed using selection buttons and pull-down menus. Graphing templates are available for plotting the annual data trends. The CD runs under Windows 3.1 and higher.
Request CD Number: PTSD-00-013-CD The second CD contains the same data content as the first CD, but stores the data in other forms (ASCII, DBF, etc.) used by analysts who process their own data. This CD also includes annual and daily summaries in table format, which are accessible through selection buttons and pull-down menus. Graphing templates are available for plotting the annual data trends.
Request CD Number: PTSD-00-014-CD There was not enough space to carry complete hourly data for all the years. Consequently, the hourly data for the earliest years have been made available for downloading from the internet: Voyager hourly files 1980-1989 ASCII hourly files 1980-1989 "arb.ca.gov/aqd/aqdcd/aqdcddld.htm"
