Polysaccharides, Proteins, and Phytoplankton Fragments: Four Chemically Distinct Types of Marine Primary Organic Aerosol Classified by Single Particle Spectromicroscopy

Figure 4

Relative carbon images of representative particles for (a) PsI, (b) PsII, (c) calcareous phytoplankton, and (d) proteinaceous particle types. For each image, the red-blue color scale is relative to individual particle carbon absorption, where red denotes the maximum carbon absorption and blue denotes the minimum.
