OTHER COMMENTS:
Yesterday remained typically maritime with relatively clean conditions although wind direction persisted around the northern edge of the clean sector. Fishing boats upwind were a nuisance off and on all day with spikes of particles, NOX and on one occasion NH3 being observed.
Today is non-baseline, (northerly). There have been no changes in instrument status since the last report.
