Abstract:

The Southern Oscillation Index (SOI) at NCAR is computed using monthly mean sea level pressures at Tahiti (T) and Darwin (D). The SOI [T-D] is an optimal index that combines the Southern Oscillation into one series. These SOI values are slightly different than those calculated by the Climate Prediction Center ("http://www.cpc.ncep.noaa.gov/") due to the normalization used. The [T+D] series is a measure of small scale and/or transient phenomena that are not part of the large scale Southern Oscillation. To access the SOI data at NCAR, see: "http://www.cgd.ucar.edu/cas/catalog/climind/soi.html" or "ftp://ftp.cgd.ucar.edu/pub/shea/soi_dir/"

Attribute_Accuracy_Report:

The SOI values prior to 1935 should be used with caution. There are questions regarding the consistency and quality of the Tahiti pressure values prior to 1935. Perhaps a better estimate of the SOI prior to 1935 is the normalized Darwin pressure anomaly series.
