I’ve moved to WordPress. This post can now be found at June 2009 SST Anomaly Update
############UPDATE
Many thanks to Anonymous for reminding me of the fuller SST and SST anomaly mapping capabilities of NOMADS. Link:
http://nomad3.ncep.noaa.gov/cgi-bin/pdisp_sst.sh?ctlfile=monoiv2.ctl&varlist=on&new_window=on&ptype=map&dir=
Anonymous also suggested the following settings, which work quite well:
Contour interval for var1 = .5 & white = 0
I’ve revised the map for June 2009 based on these settings.
MONTHLY SST ANOMALY MAP
The map of Global OI.v2 SST anomalies for June 2009 provided by NOMADS is shown below.
http://i26.tinypic.com/23tl3xg.jpgJune 2009 SST Anomalies Map (Global SST Anomaly = +0.29 deg C)
MONTHLY OVERVIEW
Global SST anomalies rose approximately 0.09 deg C in June, with the two biggest contributors being the North Pacific with a rise of 0.24 deg C and the North Atlantic with a rise of 0.19 deg C. The South Atlantic is indicating a decline from its record high SST anomalies. The equatorial Pacific shows El Nino conditions (Monthly NINO3.4 SST Anomaly = +0.62 deg C and Weekly NINO3.4 SST Anomaly = +0.88 deg C). Monthly NINO3.4 SST anomalies rose 0.35 deg C in June.

AMO
My Usual AMO Blurb: The Atlantic Multidecadal Oscillation as calculated by the NOAA ESRL is North Atlantic SST anomalies that have been detrended. Since OI.v2 SST data begins in November 1981, it does not seem appropriate to use a 28-year trend on a cycle that lasts about 60 years, so I am NOT presenting the AMO.
Using North Atlantic SST anomalies as a reference, the AMO should have recently risen from its low this year in February. Scroll down for the North Atlantic SST anomalies.
NOTE ABOUT THE DATA
The MONTHLY graphs illustrate raw monthly OI.v2 SST anomaly data from November 1981 to June 2009.

How do you obtain those beautiful maps and timeseries?
I go to the NOMADS link but I obtain awfully looking plots, and also was difficult to find the correct option.
Help please!!
Anonymous: For the time-series graphs, I download the data and create the graphs on EXCEL. On the DISPLAY PLOT page, first select ANOMALY in the FIELD dropdown menu. Then enter the coordinates you want. Click on PLOT. On the next page, NOMADS creates that "awfully looking plots". Scroll down, and click on the link that starts with "Download data file...". If you selected monthly data on the original menu, the column of data are the SST anomalies for the coordinates you input, starting in November 1981 and running to present.
For the Map, start at the NOMADS OI.v2 “start page”:
http://nomad3.ncep.noaa.gov/cgi-bin/pdisp_sst.sh?lite=
Click on GO TO FULL VERSION.
On the next page, select “monoiv2.ctl Monthly OIvsSST”. The PLOT TYPE default is MAP so click on NEXT PAGE.
On the next page, again in the FIELD dropdown menu, select ANOMALY. In the “Contour interval for var1:” field enter 0.5 and under the “white:” field enter 0. Click on PLOT. That should be the same map I used above.
Regards.
