Same as Fig. 3 but for relative biases (units:  %, from 2nd column). Note that the first column is identical to that in Fig. 2 and shown here as a reference. The relative bias is defined as (reanalysis-ozonesonde)/ozonesonde × 100 for each month. Here, we present three stations and the other two stations can be found in supplementary information
