Atmospheric H2 Concentrations from the CSIRO GASLAB Flask Sampling Network
An annual cycle of H2 is evident, reflecting the seasonal nature of some of the major sources and sinks (Novelli et al., 1999). Annual average concentrations since 1992 have varied between 473 and 499 ppb, peaking in 1998. The annual increase for H2 at Alert was highest in 1998, the same year in whi...
