<abstract>
<p>The MANTRA (Middle Atmosphere Nitrogen TRend Assessment) 2004 campaign took
place in Vanscoy, Saskatchewan, Canada (52&amp;deg; N, 107&amp;deg; W) from 3
August to 15 September, 2004. In support of the main balloon launch, a suite
of five zenith-sky and direct-Sun-viewing UV-visible ground-based
spectrometers was deployed, primarily measuring ozone and NO&lt;sub&gt;2&lt;/sub&gt; total
columns. Three Fourier transform spectrometers (FTSs) that were part of the
balloon payload also performed ground-based measurements of several species,
including ozone. Ground-based measurements of ozone and NO&lt;sub&gt;2&lt;/sub&gt; differential
slant column densities from the zenith-viewing UV-visible instruments are
presented herein. They are found to partially agree within NDACC (Network for
the Detection of Atmospheric Composition Change) standards for instruments
certified for process studies and satellite validation. Vertical column
densities of ozone from the zenith-sky UV-visible instruments, the FTSs, a
Brewer spectrophotometer, and ozonesondes are compared, and found to agree
within the combined error estimates of the instruments (15%). NO&lt;sub&gt;2&lt;/sub&gt;
vertical column densities from two of the UV-visible instruments are
compared, and are also found to agree within combined error (15%).</p>
