How do the size and depth of this year's ozone hole (plus symbols) compare with last year's (solid line) and with the entire Nimbus 7 TOMS climatology (shaded)? (10K/graph).
The white curve shown on each of the plots is the climatological mean.

As discussed in the User's Guide, the EP/TOMS working diffuser is deployed every week to make solar
measurements. The EP/TOMS reference diffuser is deployed only every 10 weeks, So the working to reference ratio indicates degradation of
the working diffuser, which is critical to the long-term calibration of EP/TOMS. Every time a working diffuser measurement is made, the near
real-time calibration of EP/TOMS is extrapolated for another week to permit continuous processing of the data. The following graphics are used
to monitor the quality of this calibration system. The upper plot in both graphics pertains to the single 360 nm channel and affects the
calibration of the derived reflectivity. The middle plot pertains to the 331 nm / 360 nm ratio, which affects the aerosol index. The bottom
plot pertains to the A-triplet of channels, which corresponds to ozone errors.
