Number of fires occurring in Moscow during August from 1996 to 2010. Although all fires are not detected due to satellite revisit times and cloud coverage, the plot is statistically representative from one month to the other and from one year to the other.

These data are based on results from the Along Track Scanning Radiometer (ATSR) on ESA’s ERS-2 satellite and the Advanced Along Track Scanning Radiometer on Envisat. Data from these sensors are compiled to create ESA’s ATSR World Fire Atlas which is available online to users within six hours.

The ESA global detection of hot spots by ERS-2's Along Track Scanning Radiometer (ATSR-2) and Envisat's Advanced Along Track Scanning Radiometer (AATSR) from July 1996 to August 2010. These twin radiometer sensors work like thermometers in the sky, measuring thermal infrared radiation to take the temperature of Earth's land surfaces. Temperatures exceeding 312º K (38.85 ºC) are classed as burning fires.
