Summary
A transportable laser system for remote sensing of road traffic emissions (carbon monoxide) has been developed and field testet at different sites in the city of Frankfurt. Based on the DAS technique using lead-salt diode lasers, the system yields mean values of the species density across a measurement path of several hundred meters. Interference with other absorbing species as well as varying operating conditions are compensated by using the second derivative technique.
The time for starting operation after transportation of the system was two hours, time of availability during the campaign was better than 90%. It appeared sufficient to have technical checks and readjustments only once per day.
