El Chichón
| origin | El Chichon volcano in Mexico. The particles were collected at a few kilometers from the vent within 24 hours after an eruption in 1982 |
| main constituents | volcanic silicate ash |
| practical significance | interpretation of remote sensing data. Analogues of other planets' atmospheric dust, and dust in comets, asteroids, and circumstellar shells |
| particle size | measured size distributions Fraunhofer: reff=3.2 μm, veff=5.4 |
| particle shape | irregular |
| refractive index | estimated to be in the range [1.5-1.6] + i0.001 |
| color | very similar to Pinatubo color |
| scattering matrix | 632.8 nm |
