Smith and Reynolds NCDC Level 4 Historical Reconstructed SST Monthly Version 3b netCDF

The Smith & Reynolds Extended Reconstructed Sea Surface Temperature (ERSST) Level 4 dataset provides a historical reconstruction of monthly global ocean surface temperatures and temperature anomalies over a 2 degree spatial grid since 1854 from in-situ observations based on a consistent statistical methodology that accounts for uneven sampling distributions over time and related observational biases. Version 3b of this dataset implements release 2.4 of ICOADS (International Comprehensive Ocean-Atmosphere Data Set) and is supplemented by monthly GTS (Global Telecommunications Ship and buoy) system data. As for the prior ERSST version, v3b implements Empirical Orthogonal Teleconnection analysis (EOT) but with an improved tuning method for sparsely sampled regions and periods. ERSST anomalies are computed with respect to a 1971-2000 month climatology. The netCDF version of ERSST v3b contains extended reconstructed sea surface temperature, SST anomaly, and associated estimated SST error standard deviation fields in netCDF classic format with CF1.0 standard metadata.
