Seasonal and interannual variations of global fire and aerosol from satellite observations

Statistical analyses of the Tropical Rainfall Measuring Mission Science Data and Information System (TSDIS) pentad fire composite data identified 25-60 day intra-seasonal oscillations that are superimposed in the annual cycles of global bio-mass burnings. The results also indicated interannual variations of fires associated with 1998/1999 ENSO cycle in Indonesian and Central America. Similar statistical methods were used to analyze the Total Ozone Mapping Spectrometer aerosol index product. The results were consistent with those derived from the TSDIS fire data.
