Short summary

In this work we compare three key constituents of the middle atmosphere (ozone, NO₂, and NO₃) from the GOMOS satellite instrument with the WACCM model. We find that in the stratosphere (below 50 km) ozone differences are very small, but in the mesosphere large deviations are found. GOMOS and WACCM NO₂ agree reasonably well except in the polar areas. These differences can be connected to the solar particle storms. For NO₃, WACCM results agree with GOMOS with a very high correlation.
