| Summary: | A massive forest fire in Indonesia in 1997 affected the whole Asian
region by producing a large smoke plume, with Malaysia bearing the brunt due
to the wind direction and weather conditions and because of its proximity to the
source. The five primary fire produced pollutants were carbon monoxide (CO),
sulphur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3) and particulate
matter less than 10 mm (PM10). The first four of these are, of course, invisible to
conventional satellite-flown multispectral scanners operating in the visible and
near infrared regions of the electromagnetic spectrum. The fifth, PM10, is
present in the haze and therefore makes an observable contribution to the signal
received by the Advanced Very High Resolution Radiometer (AVHRR). The
haze in AVHRR channels 1 and 2 data for the fires of September 1997 has been
used to study the concentration of PM10 directly. It has also been used to study
the concentration indirectly—as a tracer or surrogate—for the four remaining
materials, the gases CO, SO2, NO2 and O3. Data from ground observations have
been used to calibrate the results and the distributions of the fire pollutants over
Peninsular Malaysia have been plotted. |
