The Ozone Monitoring Instrument (OMI) onboard the Aura spacecraft is measuring total column ozone at high spatial resolution.
Initial measurements from OMI with a preliminary calibration are used to derive TOMS-like total ozone using only 4
wavelengths (312nm, 318nm, 331nm, 360nm) from OMI_s UV2 channel. These OMI total ozone measurements are compared to ozone
values from Earth-Probe TOMS (EP/TOMS), SBUV/2, and an ensemble of ground stations. The Aura spacecraft has an equator
crossing time of approximately 1:50 pm and a field of view (FOV) of 13km x 24km square while EP/TOMS has a larger FOV ranging
from 40 to 100km depending on the scan position and an equator crossing time of approximately 10:50 am. NOAA-16 SBUV/2 has
an equator crossing time of approximately 2:00 p.m which is much closer to that of OMI but the field of view is 190 km
square. Differences are analyzed as a function of latitude, solar zenith angle, total ozone, aerosol index, and reflectivity.
