Subject: Soliciting Comments on the Experimental Water

         Information Interface Webpage until February 21, 2017

 

Effective August 2016, the National Water Center (NWC) within

the NWS Office of Water Prediction (OWP) will begin hosting

water information from the National Water Model (NWM) on its

Experimental Water Information Interface Webpage.

 

The Experimental Water Information Interface Webpage is a

mapping interface that allows users to display a range of water

information including snow depth; snow water equivalent; and

output from the NWM, including streamflow, streamflow anomaly,

and soil saturation images and hydrograph displays for 2.7

million river reaches depicting short-, medium-, and long-range

streamflow forecasts.

 

The NWM is an hourly uncoupled hydrologic analysis and forecast

system that provides streamflow for 2.7 million river reaches

and other hydrologic information on 1km and 250m grids.

The NWM provides a multi-scale, parallelized, process-based

water cycle modeling capability. Upon initial implementation,

the NWM system will provide multiple country-wide hydrologic

analysis products and forecast output across a range of forecast

lead times. These products will be combined with other data from

NOAA to provide the nation with comprehensive information on a

range of water-related concerns such as snowpack, soil moisture,

and potential areas of flooding.

 

Users will be able to view data via the interactive map viewer

on the NWC webpage at:

 

http://water.noaa.gov/map

 

Data sets available for display include:

 

- snow depth images

- snow water equivalent images

- forecast streamflow images

- forecast streamflow anomaly images

- forecast soil saturation images.

 

In addition to GIS-based displays, the mapping interface also

includes hydrograph displays for 2.7 million river reaches

depicting short-, medium-, and long-range streamflow forecasts.

 

Additionally, the full set of NWM output and forcing files will

be available on the National Model Archive and Distribution

System (NOMADS) and NOAA’s National Centers for Environmental

Prediction (NCEP) FTP server at:

 

http://nomads.ncep.noaa.gov/pub/data/nccf/com/nwm

and

ftp://ftpprd.ncep.noaa.gov/pub/data/nccf/com/nwm

 

NWS is requesting comments on the Experimental Water Information

Interface Webpage until February 21, 2017.

 

The Product Description Document for the Experimental Water

Information Interface Webpage can be accessed from:

Interface Webpage at:
