Accessing ET Model Guidance

As of November 2014


Multiple sources of model guidance for coastal inundation, developed by NWS and NOS, are available here. In the following descriptions, HH = last forecast hour in UTC and YYYYMMDD = year month day format ('20150126' or '20170814')


ETSS

SLOSH-based, GFS-driven four-day forecasts are available four times per day. POC: Arthur Taylor


Model text products (hourly water level data at station points):


Model gridded products (in GRIB2 format; hourly; NDFD grid):

Compare model products under development here.

Total water level guidance (bias-corrected where observations are available) based on ETSS model output is plotted in hydrographs at the following locations:

An archive of ETSS model output for stations in Alaska is available here and provides surge data from as early as 2007.


ESTOFS

ADCIRC-based, GFS-driven 7.5 day forecasts are available four times a day. ESTOFS generates three water level records: a harmonic tide prediction, the subtidal water level (i.e. surge), and a combined water level of surge and tide. POC: Jesse Feyen

Six-minute water level data at station points is available in NetCDF at this site:


Hourly gridded water level data are available in GRIB2 (NDFD 2.5km grid) and NetCDF (native unstructured grid) via NOAAPORT and SBN at the sites below. WFOs Taunton and Wakefield are processing and displaying the GRIB2 data (POC: Matthew Belk).

Total water level guidance (bias-corrected where observations are available) based on ESTOFS model output is plotted in hydrographs here.
