The May 2011 Reynolds OI.v2 Sea Surface Temperature (SST) data through the NOAA NOMADS website won’t be official until next Monday, June 6th. Refer to the schedule on the NOAA Optimum Interpolation Sea Surface Temperature Analysis Frequently Asked Questionswebpage. The following are the preliminary Global and NINO3.4 SST anomalies for May 2011 that the NOMADS website prepares based on incomplete data for the month. I’ve also included the weekly data through May 25, 2011, but I’ve shortened the span of the weekly data, starting it in January 2004, so that the variations can be seen.
