Global carbon monoxide concentrations, November 2006. Satellite image showing the concentration of carbon monoxide (CO) in the atmosphere at an altitude of 3 kilometres. CO is measured in parts per billion and ranges from very little CO (blue), average (green, 150) to high (red, 300). Areas of grey are where data could not be collected. The source of high levels of CO is the burning of land due to wildfire or deliberate land clearance. El Nino year, and the increase in wildfires and associated CO levels over Indonesia and Sumatra (right) has been linked to the increased drought conditions of this year. This map may be compared to one from the previous year, which was not an El Nino year. To see this map see E180/463. The map was created using data collected by the Measurements of Pollution in the Troposphere (MOPITT) sensor on the Terra satellite.
