  1. CARVE Airborne PFP measurements and analysis John Miller, Colm Sweeney, Anna Karion, Steve Montzka, and the CARVE Science Team

  2. NOAA CARVE Measurements • Aircraft (CRV-a): Flask and In situ • Main GHG + related gases • CO2, CH4, CO, H2, N2O, SF6 • Halogenated gases, COS (OCS), Hydrocarbons • 13C:12CO2, 13C:12CH4, (limited 14CO2) • Tower (CRV-t): Flask and In situ • BRW and CRV-t 14CH4 sampling • BRW in situ CO2, CH4, CO
