I mentioned that I would get a comparison of SOI against sea-level height data in the ENSO region. This is the comparison with of SOI with MSLA averaged over the NINO 3 region over the time period where satellite altimetry measurements are available -- the circles are SOI data and there are two linear combinations of MSLA overlaid :


Note that the agreement is good but the mean sea level anomaly (MSLA) does not show the overall trend that the SOI exhibits
