 Sooner or later, we will have to recognize that the Earth
has rights, too, to live without pollution. What mankind
must know is that human beings cannot live without
Mother Earth, but the planet can live without humans.

•beginning in 1970 with BUV on Nimbus-4
•Map ozone profiles at 36 x 48 km
•Distinguish between aerosol types, such as smoke, dust, and sulfates
•Near Real Time (NRT) production of ozone and other trace gases
•Measure key air quality components such as NO2, SO2, BrO ,
