|Baring Head - Niwa|
|NIWA's Baring Head monitoring station|
|Matt Evans and air tanks.|
Sample air lines are mounted high on a mast and air is pumped through the air lines to tanks. Equipment here take continuous measurements of the air.
We also had 2 glass (almost balloon-like) flasks to take a sample of air outside in the southerly. To take the sample, we had to go outside facing south and hold the 'glass balloon' up, hold your breath, and open the valve. There was a hissing sound as the vacuum was filled and you then had to quickly close the valve- All took less than 10 seconds.
One of these is taken back to Niwa for testing. The other is sent over to the Scripps Institution of Oceanography (SIO),
University of California at San Diego.
|35 knot southerly outside- relatively calm!|
Here in this small video, Dr Katja Riedel, Tropospheric Chemistry, explains what they do out at Baring Head.
