This paper delas with the remote sensing system dDIM, which operates in the pulse mode using tunable diode lasers. The dDIM system enables the simultaneous sensing of two gaseous pollutants through the parallel operation of two diode lasers using the same optical path. The respective laser pulses are offset in time. The special features of this system are its compact size (325mm by 142mm by 375mm) and its stand-alone, mains-independent operation, which permits flexible and mobile use. This paper introduces the initial results of the application of dDIM in measuring methane while monitoring a landfill. The measurements were undertaken in comparison to a conventional measuring device. The influence of band overlapping in measuring methane at atmospheric pressure will be further dealt with using simulations.
