Laser and Optical Techniques Employed in Enviromental Monitoring
(1988)- Abstract
- Monl torlng of trace gases in the atmosphere has been performed wl th
differential absorption lldar and differential optical absorption

A new mobile differential absorption lldar system has been constructed.
It is described in detail and examples of 502 and N02 measurements are
given. Studies of the N02 concentration distribution in an urban area
during a temperature inversion were performed. ~tection of c12 with

geothermal energy exploration was investigated during a field test in
Iceland. Contrary to expectations very low mercury concentrations were
detected.
A high-resolution differential optical absorption spectroscopy system
has been constructed and applied in long-path moni torlng of 502 and
N02. Detection of atmospheric atomic mercury was investigated.
A multipass absorption cell (White cell) has been constructed and used
for spectroscopic measurements. Weak oxygen absorption lines in the
vicinity of the Hg line were studied both with laser and optical
techniques. (Less)
