- Abstract:
- Air bubbles in Antarctic ice will be extracted to determine trends of multiple trace non-methane and halogenated organic gases over 300 y, i.e. from pre-industrial times to the mid-20th century. This will complement our foregoing research on firn air records of trace gases over the last half-century. Atmospheric chemical models will help deconvolute sources and sinks of the same gases. Particular attention will be given to CH3Cl, CH3Br, and COS as probes of sources (biomass burning, oceanic emissions, industry, etc.) and sinks (oxidation by OH, uptake by the oceans and soils, etc.). Measurements of NMHCs and alkyl nitrates will help constrain models of past oxidative chemistry (OH and ozone). In synthesis, the impact of anthropogenic emissions on stratospheric halogen loading, oxidative capacity, and accumulation of halogenated greenhouse gases will be assessed.
