Figure 9: Anomalies in TOA radiation for the Niño 3.4 region. The top panel shows those for OLR from the NOAA series of satellites adjusted for homogenity (thin line), Nimbus 7 (dotted), ERBE (heavy), and CERES (dashed). The base period in each case is that of ERBE. The bottom panel shows the net radiation from Nimbus 7, ERBE and CERES all relative to the ERBE base period.
