INVESTIGATION OF TRACE GAS TO AEROSOL RELATIONSHIPS OVER BIOMASS BURNING AREAS USING DAILY SATELLITE OBSERVATIONS

摘要

We investigate the spatial and temporal relationshipsrnbetween satellite observations of selected trace gasesrn(CO, NO2, HCHO, CHOCHO), the UV aerosol indexrn(UVAI) and the aerosol optical depth (AOD) measuredrneither by satellite or from ground. In contrast tornprevious studies we use daily observations, since onlyrnfrom daily observations information on individualrnbiomass burning events can be obtained. Unlike thernAOD, satellite observations of trace gases and UVAIrnare possible in the presence of clouds. This might bernimportant for the study of aerosol-cloud-interactions.
