Its all about observations of earth atmosphere from space .
While Tropomi doesn’t directly measure carbon dioxide, the instrument takes daily snapshots of carbon monoxide levels in the atmospheric column beneath it. These data have been used to calculate a detailed manipulate of the carbon monoxide emissions from the bushfires, which were then used as a proxy for calculating carbon dioxide emissions. Which helps us to measure
The conclusion is that the bushfires released about 700 million tonnes in just three months. This is twice the amount of carbon dioxide that had previously been suggested by fire inventory estimates and surpasses Australia’s normal annual bushfire and fossil fuel emissions by 80%.
