NOAA NCEI Extended Reconstructed Sea Surface Temperature

| DOI: 10.5065/JZ08-3W17

The NOAA NCEI (National Center for Environmental Information) Extended Reconstructed Sea Surface Temperature (ERSST) dataset is a global monthly sea surface temperature dataset derived from the International Comprehensive Ocean-Atmosphere Dataset (ICOADS). Production of the ERSST is on a 2 degree grid with spatial completeness enhanced using statistical methods. This monthly analysis begins in January 1854 continuing to the present and includes anomalies computed with respect to a 1971-2000 monthly climatology. The newest version of ERSST, version 5, uses new data sets from ICOADS Release 3.0 (Sea Surface Temperatures) SST; SST comes from Argo floats above 5 meters, Hadley Centre sea ice and SST version 2 (HadISST.2) ice concentration. ERSSTv5 has improved SST spatial and temporal variability by

  1. reducing spatial filtering in training the reconstruction functions Empirical Orthogonal Teleconnections (EOTs),
  2. removing high-latitude damping in EOTs,
  3. adding 10 more EOTs in the Arctic.
ERSSTv5 improved absolute SST by switching from using Nighttime Marine Air Temperature (NMAT) as a reference to buoy SST as a reference in correcting ship SST biases. Scientists have further improved ERSSTv5 by using unadjusted First-Guess instead of adjusted First-Guess.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
