More interesting information at justdata, my other blog, where I hash over raw GHCN data.
Best bet: This ends in 2007, but looks promising. Extracts Lat, Long, AirTemp, SST. Update- this only works on the old records. Haven’t deciphered the newer ones, yet.
Seems to have raw temperatures, but only found one year, so far. No indication what year that is http://iridl.ldeo.columbia.edu/SOURCES/.RC/.sst/?help+datatables This may be promising HadlSST1, I’ll have to download & unpack to see if they’re useable. Methods paper for HadlSST1. Look for weather logs, instead? ARGO data here. Yaargh, dis may be da motherlode.
