| title: | NOAA Extended Reconstructed SST V3 |
| conventions: | CF-1.0 |
| history: | created 09/2007 by CAS |
| comments: | The extended reconstructed sea surface temperature (ERSST)
was constructed using the most recently available
Comprehensive Ocean-Atmosphere Data Set (COADS) SST data
and improved statistical methods that allow stable
reconstruction using sparse data.
Currently, ERSST version 2 (ERSST.v2) and version 3 (ERSST.v3) are available from NCDC.
ERSST.v3 is an improved extended reconstruction over version 2.
Most of the improvements are justified by testing with simulated data.
The major differences are caused by the improved low-frequency (LF) tuning of ERSST.v3
which reduces the SST anomaly damping before 1930 using the optimized parameters.
Beginning in 1985, ERSST.v3 is also improved by explicitly including
bias-adjusted satellite infrared data from AVHRR. |
