Data in table tells us about the average gaseous composition of dry air. Gas includes- Nitrogen, oxygen, argon, carbon dioxide, neon, helium, methane, krypton, hydrogen, xenon and ozone. Table tells us both composition types- Percent by Volume and Parts Per Million (ppm)* for every gas.
Note: Updated values by Indian Institute of Tropical Meteorology, Pune.
