The background current IB is subtracted from the measured cell current IM.

You must give the background current IB used in the calculations as part of the ozone preparation data. The background current is constant, that is, no air pressure dependent correction is applied.

GAW Report 268 recommends using IB1 as the background current. Existing stations must not change their procedure without analyzing the impact.
