CORRELATION BETWEEN SOLAR-RADIATION AND TOTAL SUSPENDED PARTICULATE MATTER IN SANTIAGO, CHILE - PRELIMINARY-RESULTS

This is a first-approach study tending to correlate solar radiation an d temperature with total particulate matter in Santiago, Chile, a city heavily polluted by this contaminant. Experimental data for monthly a verage total radiation, (G) over bar were provided by the Chilean Mete orological Bureau. Diffuse monthly average radiation, (D) over bar, wa s calculated. The concentrations of TSP were provided from the monitor ing system of the Chilean Environment Health Service. Results show tha t there exists a relationship between TSP and solar radiation and temp erature for urban sites, but not for suburban sites, even considering the monthly average values. Further and more detailed studies are nece ssary in this field.
