Smoke from forest and savannah fires in Africa absorbs much more solar radiation than was previously thought. This has become clear from analyses conducted by researchers from the Royal Netherlands Meteorological Institute (KNMI) and TU Delft on smoke measurements made by the SCIAMACHY satellite instrument. The scientists have recently published their findings in Geophysical Review Letters. The research results are an important step forward in climate research, as it will make it possible to more effectively incorporate the radiation process between clouds and smoke in climate models. Sciamachy is a German-Dutch-Belgian satellite instrument aboard the ESA satellite Envisat.
