The map of the median particle size has been plotted utilizing data found in literature.
The data on soil particle size was gathered from academic articles reporting soil particle parameters on solar photovoltaic cells and concentrators.
Geographical locations of dust source are plotted on the map as colored rings.
The color of the rings corresponds to mean or median dust particle diameter (µm).
Legend provides visual guide to particle sizes plotted on the map.
Please contact me (see below) for the list of articles used in the study

Clicking on the ring on the map reveals:
1) Article Number – Location of study
2) Mean/median diameter of dust reported (mean and average are identical)
3) Method of particle size analysis as reported by the article (when available)

A literature search was performed on Web of Science.
