Comment: Note: the requirement on uncertainty varies considerably with phase of the solar cycle as the atmospheric temperature in the high thermosphere varies. The threshold value of uncertainty is approximately 140 K during solar maximum and 70 K during solar minimum. Confidence: tentative
Def: :Positive impact expected but not yet validated due to lack of suitable data and/or models
  • Domain: Atmosphere
