After the balloon bursts, DigiCORA calculates the residual ozone ΩR with the following equation in which the level of ozone is estimated with a constant mixing ratio (p3i = p3i+1 = p3END) up to ambient pressure 0 hPa.
GAW Report 268 recommends deriving the residual ozone column from the satellite climatologies of McPeters and Labow 2012, which also gives uncertainties for residual columns. If you want to use another calculation method, you can do that in post calculation. |
