These data and post script files were created by Susan Strahan.
The post script file is Plate 5 from "Climatologies of lower stratospheric
NOy and O3 an correlations with N2O based on in situ observations", JGR,
in press. 

The equivalent latitude data have been smoothed and interpolated as described
in the paper. Interpolation has been applied over single point gaps in the
latitude coordinate data, but there was no smoothing.

*********************************************************************

To restore the equivalent latitude-coordinate climatology:

	IDL> restore, 'o3_eqlat_theta.idl'

This will restore 3 arrays: o3eqlat, blat, and tht
o3eqlat is (91,35,4)
eqlat is (91)
tht is (35)
91 latitudes from -90 to 90, every 2 degrees.

To restore the latitude-coordinate climatology:

        IDL> restore, 'o3_lat_theta.idl'

This will restore 3 arrays: o3lat, blat, and tht
o3lat is (81,35,4)
lat is (81)
tht is (35)
81 latitudes from -72 to 88, every 2 degrees.

**********************************************************************

For both files:
35 theta levels from 360 to 530, every 5 K
4 seasons: DJF, MAM, JJA, and SON.
Data is in ppb. Missing values are '99999'.
