Jb. Burkholder et Rk. Talukdar, TEMPERATURE-DEPENDENCE OF THE OZONE ABSORPTION-SPECTRUM OVER THE WAVELENGTH RANGE 410 TO 760 NM, Geophysical research letters, 21(7), 1994, pp. 581-584
The ozone, O3, absorption cross sections between 410 and 760 nm, the C
happuis band, were measured at 220, 240, 260, and 280 K relative to th
at at room temperature using a diode array spectrometer. The measured
cross sections varied very slightly, < 1%, with decreasing temperature
between 550 and 660 nm, near the peak of the Chappuis band. At wavele
ngths away from the peak, the absorption cross sections decreased with
decreasing temperature; e.g., approximately 40% at 420 nm between 298
and 220 K. These results are compared with previous measurements and
the impact on atmospheric measurements are discussed.
