Abstract: INFRARED TUNABLE DIODE LASER SECOND DERIVATIVE MODULATION SPECTROSCOPY HAS BEEN USED TO MONITOR TRACE GASES IN THE TROPOSPHERE: IN THE CASE OF UNSTABLE OR REACTIVE GASES HOWEVER, CALIBRATION OF THE MEASUREMENT IS A DIFFICULT TASK. IN SOME CASES, THE ABSORPTION DUE TO ATMOSPHERIC CARBON DIOXIDE OR NITROUS OXIDE SIMULTANEOUSLY RECORDED WITH THE TRACE GAS ABSORPTION APPEARS USABLE AS A BUILT-IN CALIBRATION STANDARD: THE PROCEDURE IS DISCUSSED AND EXAMPLES OF POTENTIAL APPLICATIONS ARE GIVEN.
