Description:

Average surface temperature changes world wide and in the Northern Hemisphere 3 and 10 years after the injections of 5, 50 and 150 Tg (teragrams = millions of metric tons) of smoke into the upper troposphere, per Robock, Oman, and Stenchikov (2007).

These numbers are relative to the average for 1925-1975, which explains why the numbers are positive with smoke = 0.

Variables:

A dataframe containing :

smoke

teragrams = millions of metric tons

dC3g, dC10g, dC3n, dC10n

average change in surface temperature 3 and 10 years after injection of smoke into the upper troposphere globally (g) or in the Northern Hemisphere (n) in degrees Celsius.
