Abstract: ML2SO2 is the EOS Aura Microwave Limb Sounder (MLS) standard product for sulfur dioxide derived from radiances measured by the 240 GHz radiometer. The current version is 3.3. Spatial coverage is near-global (-82° to +82° latitude), with each profile spaced 1.5° or ~165 km along the orbit track (roughly 15 orbits per day). The recommended useful vertical range is from 215 to 10 hPa, and the ... View entire text
