Measurements of atmospheric methyl bromide and bromoform

We have measured gaseous methyl bromide (CH3Br) and bromoform (CHBr3) in air samples that were gathered approximately weekly from five ground-level sites: Point Barrow, Alaska; Mauna Loa Observatory and Cape Kumukahi, Hawaii; Matatula, Samoa; and Kaitorete Spit, New Zealand. Approximately 750 sample...
