Voyager Files

This page last reviewed April 27, 2010

The Voyager data exploration software enables the user to view a great variety of data in easily understood graphical formats arranged in three idependent contextual domains: space, time, and variable. MLD staff have generated several Voyager files containing aerometric data. The following is an index of files available for downloading (the Voyager software is required to view the data files).

Data and Map Files 

Description (File name, Size) 



California Map PKWare zipped file containing a map of California. (calif.zip, 244K) 
Central Valley Map PKWare zipped file containing a map of California's Central Valley. (cntlvly.zip, 44K) 
Bakersfield Particulate Data PKWare zipped file containing particulate air pollutants data and meteorological data collected at the Bakersfield - California Avenue site from November 19, 1994 through March 31, 1995. The principal objective of the Bakersfield Winter PM Study was to examine the performance of a variety reference and non-reference PM10 samplers and several PM2.5 samplers in an environment and during a season that would challenge any sampler. In addition to a meteorological system, 12 integrated particulate samplers and four continuous particulate monitors were operated in the study. The integrated sampling was performed every three days. The data were evaluated in a paper published by the Air & Waste Management Association in; Particulate Matter: Health and Regulatory Issues, VIP 49, "Evaluation of Fine Particulate Samplers (PM2.5) in an Area of Volatile Constituents". (bak_pm25.zip, 571K)
Statewide Particulate PKWare zipped file containing Size Selective Inlet (SSI) High Volume Sampler mass and ion data and Dichot mass data for a period from October 1990 to March 1994. The file contains SSI chloride, nitrate, sulfate, ammonium, potassium, and total mass data (total is measured); and Dichot fine, coarse and total mass data (total is sum of fine and coarse). (pm10_s-d.zip, 91K) 
Statewide Particulate and PAMS HC Data PKWare zipped file containing preliminary data for air pollutants and pollutant precursors sampled at seven California sites from June 1, 1993 to October 30, 1993. The Voyager file was used as a quality assurance tool to review the hydrocarbon data for year zero of the U.S. EPA mandated Photochemical Assessment Monitoring Stations (PAMS) program. The data taken during the Summer of 1993 will be used to assess the California Air Resources Board's monitoring capability and preview the ambient hydrocarbon patterns. (sum93.zip, 185K)
Toxics Program Data PKWare zipped file containing preliminary data for Toxic pollutants sampled at 26 sites from January 1, 1990 to October 30, 1994. Some of these sites do not have toxic data for the entire period. The TOX_AVG.VOY database file contains quarterly and annual averages for most of the toxic compounds found in the TOXIC.VOY file. The Voyager files were used as a quality assurance tool to review the data generated. (toxicvoy.zip, 246K)
Sacramento NMHC and Criteria Pollutant Data PKWare zipped file containing criteria and NMHC pollutant data. The data were collected at four fixed sites from December 1991 through February 1992 and at six mobile sites in two week segments. The intent of the winter study was to examine the nature of sources, reactivity, and diurnal patterns of ambient hydrocarbon levels. (wntr_hc.zip, 74K)
