OTHER COMMENTS:
A weak change overnight has not resulted in a large wind direction shift
and conditions remain typically maritime although wind direction is just
around the northern edge of the baseline sector and speed has been low
(around 5 ms-1). Radon is currently around 50 mBeq m-3 CN 300-400 cm-3
and CCN @ 0.5% around 60 cm-3. The size distribution looks typically
maritime with modes at 30 nm and 150 nm diam. There have been no changes
in instrument status since the last report.
