situ measurements of bromine oxide at two high-latitude boundary layer sites: Implications of variability
[1] Bromine oxide (BrO) was measured in situ during the Arctic Tropospheric Ozone Chemistry (ARCTOC) '96 campaign in Ny Å lesund, Spitsbergen (April-May 1996), and during the Alert 2000 Polar Sunrise Experiment in Alert, Nunavut, Canada (April-May 2000). Measurements were made in near-surface a...

[1] Bromine oxide (BrO) was measured in situ during the Arctic Tropospheric Ozone Chemistry (ARCTOC) '96 campaign in Ny Å lesund, Spitsbergen (April-May 1996), and during the Alert 2000 Polar Sunrise Experiment in Alert, Nunavut, Canada (April-May 2000). Measurements were made in near-surface air during low-ozone events in early May at both sites. The average of the in situ concentrations of BrO at Ny Å lesund is consistent with the path average of near-simultaneous long-path differential optical absorption spectroscopy measurements, but there is considerable scatter in a point-by-point comparison. The differences between these observations are consistent with a strong surface influence on reactive bromine.

The fluctuations of BrO abundances are used to assess the expected loss rates and associated lifetimes of ozone during depletion events.
