Abstract
UV absorption in Valparaíso, Chile, is analyzed during the passage of a smoke column from a nearby forest fire. Total solar absorption is measured, UVB and UVA radiation, UV nanometre to nanometre between 295 nm and 315 nm. With the purpose of seeing what factors intervene in this absorption, tropospheric ozone and PM10 particulate material are measured during the passage of this smoke column from the forest fire. In addition, considerations were made on the chemical compounds which are normally present during a forest fire such as, CO2, CO, SO2, NO, NO2, etc., depreciating their evidence that is the PM10 particulate material, which acts as a black body that is primarily responsible for the UV absorption. This affirmation is based on the fact that no absorption, which notoriously indicates some particular compound, was observed on the spectroradiometer register. All of the bands, nanometre to nanometre, showed the same behaviour, indicating the same type of absorption.
