Observations by the A-Train’s MODIS/Aqua, OMI/Aura and CALIOP and IIR (CALIPSO) instruments, showing a high density of carbon and mineral particulate matter transported to very high altitudes (into the lower stratosphere) with a strong potential radiative impact; northward and westward diabatic transport (radiative heating) across the northern hemisphere (the first such observation recorded in this region).
