We compare three datasets of high-resolution O3 cross sections and evaluate the effects of using these cross sections on O3 profile retrievals from OMI UV (270-330 nm) measurements. These O3 cross sections include Brion-Daumont-Malicet (BDM), Bass-Paur (BP) and a new dataset measured by Serdyuchenko et al. (SGWCB), which is made from measurements at more temperatures and in a wider temperature range than BDM and BP, 193-293 K. Relative to the BDM dataset, the SGWCB data have systematic biases of -2 to 4% for 260-340 nm, and the
