Several historical SST analyses have been developed by different centers over the last 10+ years. With each new analysis, problems are detected and adjustments are made. Presented here is the latest NOAA/NCDC historical SST reconstruction, which will become available in early 2007. The biggest differences between this and the previous version is improved tuning of the low-frequency component of the reconstruction. That improvement allows the analysis to produces stronger anomalies with less uncertainty in the 19th and early 20th century. Other improvements affect the more recent period. These include bias adjustment of buoys relative to ships, inclusion of bias-adjusted AVHRR satellite data, and improved sea-ice estimates.
