Ozone profiles retrieved from SAGE III limb scatter measurements are compared with correlative measurements made by two occultation instruments (SAGE II, SAGE III), a limb scatter instrument (OSIRIS) and a series of ozonesondes, in order to ascertain the accuracy and precision of the SAGE III instrument in limb scatter mode. The measurement accuracy is found to be 5-10% from the tropopause to about 45km whereas precision is found to be less than 10% from 20 to 38km. The main source of error is height registration uncertainty, which is found to be Gaussian with a standard deviation of about 400m.
