How are the SST anomalies in the IGOSS/nmc dataset calculated?

In the calculation of the SST anomalies in this dataset, the following climatology was subtracted from the SST dataset:

Documentation for this climatology can be found here:

Documentation for the dataset in general, including relevant references, can be found here:

I should point out that an updated version (version 2) of this Reynolds and Smith SST dataset is now available, and can be found here:

If you go to the monthly data or the climatology, a link to the relevant documentation can be found in the blue menu bar on the left side of the page. The Reynolds and Smith version 2 climatology is for the years 1971-2000.

I should also note that there will soon no longer be monthly updates to the Reynolds and Smith version 1 dataset -- the version 2 dataset will continue to be updated, however.
