Beschreibung
Zusammenfassung:	The method of the invention provides a simple, reproducible reference, or set of reference standards, as a validation of a calibration standard for filter-based measurements of light absorbing aerosol particles (black carbon and brown carbon) and organic carbon and elemental carbon particles found in indoor and outdoor environments, and in emission streams. The set of reference standards comprise grayscale images deposited by a mist or print at a known density on a substrate material. The reference standards may be made by a printer using as a substrate either paper or another material such as glass fiber, quartz fiber, polypropylene, or cellulose.
