TROPOSPHERIC OZONE DATA, MOVIES, AND IMAGES FROM AURA OMI/MLS
As members of the Aura Ozone Monitoring Instrument (OMI) science
team we are developing several tropospheric ozone data products from
OMI in combination with Aura Microwave Limb Sounder (MLS). One of
these involves OMI measurements alone to derive tropospheric and
stratospheric ozone. By combining OMI total column ozone measurements
with MLS stratospheric column ozone measurements, we are producing
global maps of OMI/MLS tropospheric ozone. Aura MLS stratospheric
ozone data were provided in collaboration with the Aura MLS team at
Jet Propulsion Laboratory, Pasadena, CA.
NOTES:
Below is the journal reference for the OMI/MLS tropospheric
ozone data:

The following provide links to data, movies, and images involving
Aura OMI/MLS tropospheric ozone data from NASA Goddard Space Flight
Center. The original monthly mean clear-sky measurements
[Ziemke et al., 2006] are still being provided and updated. Please

or specific questions about the datasets.
OZONE ENSO INDEX (OEI) MONTHLY TIME SERIES DATA
We have combined column ozone measured in tropical latitudes from
Nimbus 7 total ozone mapping spectrometer (TOMS), Earth Probe TOMS,
solar backscatter ultraviolet (SBUV), and Aura ozone monitoring
instrument (OMI) to derive an El Nino-Southern Oscillation (ENSO)
index. This index, which covers a time period from 1979 to near
present, is defined as the tropospheric "Ozone ENSO Index" (OEI)
[Ziemke et al., 2010, Atmos. Chem. Phys., 2010.]
Stratospheric column ozone in tropical low latitudes has very small
longitudinal variation of only a few Dobson Units. This has been
shown in previous studies from SAGE, HALOE, and UARS/Aura MLS
stratospheric ozone satellite measurements. Because of this
characteristic, the east-west zonal variation of tropospheric column
ozone in tropical low latitudes is essentially identical to that of
total column ozone. This property of near zero zonal variation of
stratospheric column ozone is used to derive the tropospheric OEI.
The OEI is calculated by differencing total column ozone between two
broad regions in the the western and eastern tropical Pacific.
Because of near zero zonal variation of stratospheric ozone, this
differencing eliminates the stratospheric ozone signal leaving only
tropospheric ozone variation in the OEI.
There are many ENSO indices that have been developed. One commonly
used ENSO index derived from sea surface temperature (SST) anomalies
is the NOAA Nino 3.4 index. Another historic ENSO index comes from
Tahiti minus Darwin surface pressure. Both ENSO indices are well
correlated with tropospheric and total column ozone with an east-west
"dipole" signature between the eastern and western Pacific in the
tropics. (See IMAGE of temporal correlation
between total column ozone and the ENSO indices Nino 3.4 and Tahiti
minus Darwin pressure (denoted SOI in figure)). On average, a +1K
change in Nino 3.4 index coincides with about a +2.5 to +3 DU change
in OEI depending on the amount of cloud scenes included in calculation
of the OEI. The more convective cloud scenes included in calculating
the OEI, the smaller becomes the OEI sensitivity number with the Nino
3.4 ENSO index. This is likely because ozone concentrations in the
lower troposphere in the remote Pacific are characteristically low and
convective clouds inject these low concentrations into the middle and
upper troposphere, reducing tropospheric column ozone and the
calculated OEI.
The OEI is a useful diagnostic test for ocean-atmosphere climate
models of the troposphere [e.g., Oman et al., Geophys. Res. Lett.,
2011]. Such models should be capable of reproducing signatures of the
ozone ENSO index including it's sensitivity relationship with ENSO
induced changes in tropical surface pressure and sea surface
temperature.
The OEI is updated periodically on this webpage. Listed below is the
OEI monthly-mean data, and a figure of these two OEI time series
versus the Nino 3.4 sea-surface temperature ENSO index.
Below is the OEI data calculated using only clear-sky scenes
for the
satellite ozone measurements:
OEI (clear-sky condition) DATA for January 1979 (top) through
December 2018 (bottom).
Below is a JPEG figure which shows the above OEI time series
plotted with the Nino 3.4 ENSO index:

ENSO indices (Note: Nino 3.4
time series was multiplied by +3 for scaling with the OEI time series)

OTHER PUBLIC DOMAIN DATA AND IMAGES, ETC. :
Monthly-mean maps (GIF images) of tropical tropospheric column
ozone (in Dobson Units) derived from the Convective Cloud Differential
(CCD) method [Ziemke et al., 1998]:
GRIDDED TROPICAL DATA:
Data for the above tropospheric column ozone images can be obtained
at this website. The data (see DATA DOCUMENTATION
) represent monthly-means with a resolution of 5 degrees latitude
by 5 degrees longitude and are printed in ASCII format for both TROPOSPHERIC and
STRATOSPHERIC column measurements.
Stratospheric column ozone to within a few Dobson Units in the
tropics is zonally homogeneous. For this reason the stratospheric
column ozone data file gives only one value for each latitude.
There is also an IDL
PROCEDURE provided to read these data tables. At current time
these CCD data files are developed from Nimbus 7 TOMS and Earth Probe
TOMS version 8 measurements. In the future, the new Aura OMI CCD data
will be appended to continue this long time-record data set.
PACIFIC AVERAGED DATA FOR 50S TO 60N:
Pacific averaged (120W-120E) monthly mean stratospheric and
tropospheric column ozone from TOMS measurements covering the
latitudes 50S to 60N (5 degree latitude bands) can be obtained here.
The tabulated data were obtain using the CCD method. Measurements for
latitudes south of 50S and north of 60N are not included in the tables
because there are not enough suitable clouds for using the CCD method.
As with the above data tables, TOMS version 8 level-2 footprint
measurements were used to construct the data. There are two ASCII
tables, one for STRATOSPHERIC
column ozone and one for TROPOSPHERIC
column ozone. Time coverage extends from January 1979 through
December 2005. Two-sigma uncertainties in these monthly measurements
of both stratospheric and tropospheric column ozone are 5 DU. There
is an IDL PROCEDURE
provided to read these data tables. Note that in the tables the two
left-most numbers designate latitude ranges (maximum and minimum) for
the measurements. It is noted that the stratospheric column ozone
measurements outside the tropics from Earth Probe TOMS began having
problems in mid-2001. Stratospheric ozone began showing an erroneous
downward trend and a signature of a solar zenith angle dependent
calibration drift. Stratospheric data for years 2001-2005 are lower
than they should be, so that the variabilities in the measurements
should be evaluated with caution. Tropospheric ozone is not affected
directly by calibration drift (it's a differencing method) and
maintains reasonable numbers through year 2005.
SPECIAL NOTES:
All of the above data tables were determined from Nimbus 7 TOMS
(Jan79-Apr93) and Earth Probe TOMS (Aug96-Dec05) satellite
measurements. Following December 2005, Earth Probe TOMS no
longer provides data. In the future, the new Aura OMI ozone
measurements will be used to continue adding to these long time
records of stratospheric and tropospheric column ozone.

measurements: The assimilated UARS MLS/HALOE and convective-cloud

TREND ANALYSIS SOFTWARE, ETC.:
MULTIPLE LINEAR REGRESSION SOURCE CODES FOR
TREND ANALYSIS AND GENERAL SCIENCE APPLICATIONS (both Fortran and IDL
software - includes example programs). The trend analysis codes
originate from Ziemke et al. [1997]:
Ziemke, J. R., S. Chandra, R. D. McPeters, and P. Newman,
Dynamical proxies of column ozone with applications to global
trend models, J. Geophys. Res., 102, 6117-6129, 1997.
(If you use the regression trend routine(s) for published work, you
may if you want list this paper as the reference to these trend
programs.) Ziemke et al. [1997] used a Monte Carlo statistical
approach. The multi-variate statistics built into the trend code can
be turned off and replaced by a Monte Carlo method by adding random
noise to the independent proxies.
FORTRAN CODE for the exact solution
(i.e., angles, distances, times, orbital speeds) to the general
two-body gravitational problem with two arbitrary masses.
FORTRAN CODE for determining the
locations and stability of the five Lagrangian points for the
generalized three-body problem with two large masses and one
infinitesimally small mass.
