According to this comment: "data set shows that this November was 2.35°C warmer than the November average—tied with November 1997’s 2.33°C" the actual measurement of SST is +/-0.01C; is that correct? I mean all the sources of SST are made with that precision. On the other hand, to measure accuracy, where is located the reference thermometer? Who check the accuracy? Thank you. franklinormaza@yahoo.com
