Abstract
Monl torlng of trace gases in the atmosphere has been performed wl th

differential absorption lldar and differential optical absorption

spectroscopy.

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

DIAL was invest !gated. Using a narrow-bandwidth laser system

range-resolved measurements of NO and Hg were investigated. Mapping of

NO and Hg plumes was performed. The use of mercury as a tracer gas for

NO and Hg plumes was performed. The use of mercury as a tracer gas for

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)
