Tg = Teragramme = 10¹² g = 10⁹ kg = 10⁶ T = megatonne.

Cl and Br mixing ratios = number of moles of Cl and Br divided by the number of moles of air in the total

atmosphere (Na = 1.8*10²⁰ moles of air) expressed as part per billion and part per trillion by volume of air

respectively.

EESC = Equivalent Effective Stratospheric Chlorine = [Cl] _{added to stratosphere} + 60 × [Br] _{added to stratosphere}, calculated.

assuming that 10% reach the stratosphere (with 2.7*10¹⁹ moles of air) for sake of comparison with ref. 43.
