We use an airborne pulsed integrated path differential absorption lidar tomake spectroscopic measurements of the pressure-induced line broadening andline center shift of atmospheric CO2 at the 1572.335 nm absorption line. Wemeasure the absorption lineshape in the vertical column between the aircraftand ground. A comparison of our measured absorption lineshape to calculationsbased on HITRAN shows excellent agreement with the peak optical depth accurateto within 0.3%. Additionally, we measure changes in the line center position towithin 5.2 MHz of calculations, and the absorption linewidth to within 0.6% ofcalculations.
