AMS Spectral Database

This page is a compliation of published spectra obtained with the Aerodyne Aerosol Mass Spectrometer.

Spectra are divided into several categories with respective ID labels:

as presented in the tables below, in which * indicates the version of the instrument (Q, C, V, and W) and xxx is the ID. Spectra are grouped by type of instrument within each category. The spectra have been added in an arbitrary order, so it may be fastest to search the text if you're looking for something specific.

These spectra have been made available to the entire community. By using these spectra you agree to make appropriate citations of the papers referenced. Please honor this request so that the spectra can continue to be available to everyone. Also please cite this database as "Ulbrich, I.M., Lechner, M., and Jimenez, J.L. AMS Spectral Database. URL: http://cires.colorado.edu/jimenez-group/AMSsd/" and the paper that describes it (Ulbrich et al., ACPD, 8, 6729-6791, 2008).

If you have spectra you'd like added to the database, please send them to Ingrid Ulbrich, along with all of the descriptive information specified here. Your comments are also welcome!
