The NASA TOMS V9 (TOMS-V9) total ozone retrieval algorithm is tested
for sensitvity to boundary-layer ozone and suitability to make daily
maps of tropospheric ozone residual (TOR).  Daily maps of TOR are
derived by differencing co-located MERRA-2 assimilated MLS
stratospheric column ozone (SCO) from total column ozone from the Aura
Ozone Monitoring Instrument (OMI).  The TOMS-V9 algorithm uses a few
discrete channels with an order of magnitude range in ozone
senstivity. We compare the TOR results from TOMS-V9 with results from
several hyper-spectral total ozone retrievals: GODFIT v4 (BIRA-IASB),
OMI-DOAS (KNMI), and total ozone from the SAO PROFOZ algorithm. We
compare all satellite-retrieved TOR with TOR derived from ozonesondes,
lidar, and the Goddard Modeling Initiative (GMI) model simulation.
