Please note: If you acquire LIM Pacific SST Anomalies and PDO Forecasts products from NOAA/PSD and CIRES/CDC, we ask that you acknowledge us in your use of the data. This may be done by including a citation to us as noted in "Description of SST prediction" below, and text, such as "LIM SST Anomalies Forecast data provided by the CIRES/Climate Diagnostics Center and Physical Science Division/ESRL/NOAA, Boulder, Colorado, from their Web site at", in any documents or publications using these data. We would also appreciate receiving a copy of the relevant publications. This will help NOAA/PSD and CU CIRES to justify keeping the LIM SST Anomalies Forecast data freely available online in the future. Thank you!
