CMB: Weekly Pacific Ocean Hindcast

NOAA NCEP EMC CMB Pacific weekly temperature

The hindcast results are derived from a model based ocean analysis system. Observed surface and subsurface ocean temperatures as well as satellite altimetry sea-level data from TOPEX/POSEIDON are assimilated into a Pacific basin ocean general circulation model. The model is forced with weekly mean NCEP operational atmospheric analyses of surface winds and heat fluxes.

The dataset is accessible as figures and downloadable datafiles.

IMPORTANT: Please note that in the "weekly" data set, the data from the week of 6-12 February 2005 onward contain output from the Global Ocean Data Assimilation System (GODAS), not from the NCEP Weekly Pacific Ocean Hindcast (WA3), which was discontinued in February 2005. In the "monthly" data set as well, the GODAS data begin in February 2005. This is a stop-gap measure until the operational GODAS data become available. You can find more information on this transition in the following README file: ftp://ftp.emc.ncep.noaa.gov/cmb/Pacific/godas_pac/README
