Medium resolution transmissivities of CO 2 were measured at temperatures between 300 and 1550 K for the 4.3, 2.7 and 2:0 m bands. Measurements were made with a new drop tube design, which guarantees a truly isothermal high-temperature gas column. Data were collected with an FTIR-spectrometer, allowing for much better spectral resolution than most previous high-temperature measurements. The measured data were compared with two line-by-line and two narrow band databases. The data show some
