The fine mass (<2.5 um) from the IMPROVE, NESCAUM, GAViM, SCENES, CARB, NPMR, NAPS, PHCO, PHLS, AIRS, MOHAVE, PREVENT, WHITEX, TVA1, SFU, and CASTNet VChem Networks. The data set has ~500 monitoring sites in the US and Canada from November 1983 through December 1997.

The format of the data file and accompaning location and variable tables are desribed in the web document North American Fine Particle Data Sets

Changes from Version 1: a) Added data from the MOHAVE, PREVENT, WHITEX, TVA1, SFU, and CASTNet VChem Networks. b) fixed IMPROVE monitoring site's latitudes and longitudes. c) data converted from ng/m3 to micro-g/m3
