Comparison of the atmospheric 137Cs (Bq m−3) for events on 15 March, 12:00 and 21 March, 9:00, as estimated by the NICAM-SPRINTARS model (N; a, c) and the WRF-CMAQ model (W; b, d). Observed values are indicated by color-coded circles (Bq m−3); triangles indicate data below the detection limit (0.1 Bq m−3) of SPM measurements
