Suomi NPP Captures Wildfire Smoke over Russia
Smoke from numerous wildfires in Russia blankets a large portion of the country in this true-color image taken by the VIIRS instrument aboard the NOAA/NASA Suomi NPP satellite on July 20, 2016.
According to information from Russia's federal forestry agency dated July 21, there were 77 forest fires burning more than 12,900 hectares (more than 31,875 acres).
According to global weather data from NOAA's National Centers for Environmental Information (NCEI), the area of central Russia in which the majority of these fires are located has experienced above average temperatures and below-average precipitation during the month of June, likely exacerbating fire conditions.
True-color images like this one are created using three of the VIIRS instrument's 22 channels -- the RGB color channels 5, 4, and 3, which are sensitive to the red, green, and blue wavelengths of light respectively. In addition, data from several other channels are also included to cancel out atmospheric interference, such as clouds and aerosols, which can cause a blurry picture.
