What is NDFD XML?

National Digital Forecast Database (NDFD) Extensible Markup Language (XML) is a service providing the public, government agencies, and commercial enterprises with data from the National Weather Service’s (NWS) digital forecast database.   This service, which is defined in a Service Description Document, provides NWS customers and partners the ability to request NDFD data over the internet and receive the information back in an XML format.  The request/response process is made possible by the NDFD XML Simple Object Access Protocol (SOAP) server.   To see the details of the NDFD XML SOAP service, go to the following URL and click on the NDFDgen or NDFDgenByDay link:

https://graphical.weather.gov/xml/SOAP_server/ndfdXMLserver.php

If the web service description provided by the SOAP server does not meet your needs, similar information is available in the following Web Service Description Language (WSDL) document:

https://graphical.weather.gov/xml/DWMLgen/wsdl/ndfdXML.wsdl

In addition to the SOAP technology, this service exploits XML to enhance the ease with which NWS customers and partners can integrate NDFD data into their computer applications.   XML is a W3C standard that allows its users to create languages with HTML-like tags and attributes.   The NDFD XML language is called Digital Weather Markup Language (DWML) and its schema can be found at the following link:

https://graphical.weather.gov/xml/DWMLgen/schema/DWML.xsd

The schema defines the XML language’s vocabulary (available tags and attributes) and syntax (expected order of tags).   Knowing how NDFD XML is constructed, users can write programs to process the XML document to get at the data it contains.

To see a sample Digital Weather Markup Language document that conforms to the DWML schema, click on any of the following links:

https://graphical.weather.gov/xml/DWMLgen/schema/latest_DWMLByDay24hr.txt
https://graphical.weather.gov/xml/DWMLgen/schema/latest_DWMLByDay12hr.txt

Why provide an NDFD XML service?

The National Weather Service is striving to serve society’s needs for weather information by evolving its services from a text-based paradigm to one based on making NWS information available quickly, efficiently, and in convenient and understandable forms.   The NDFD is one example of this transformation.   NDFD XML takes yet another step towards a digital services era by making NDFD data available for computer to computer transfer and processing.   NWS customers and partners can then enhance the value of NDFD data through the creation of value added products.

You can provide comments on this web service from the following page.

http://www.nws.noaa.gov/feedback.php

How often is NDFD XML updated?

The NDFD is updated no more than hourly. We request developers using this SOAP service for local applications only make a request for a specific point no more than once an hour. The database is currently updated by 45 minutes after the hour.

How is NDFD XML generated?

The first step to providing NDFD XML is the creation of the NDFD.   For more information on how NDFD is created, visit the NDFD home page.   With NDFD data available, a user application creates and sends a SOAP request to the NDFD XML SOAP server.   The SOAP request is processed, creating the DWML document which is returned to the requesting application for processing.   Figure 1 provides a graphical view of the process.

You can download several simple sample client applications by clicking on the following links:

https://graphical.weather.gov/xml/sample_products/ndfdXML.tar

NOTE:  These clients are examples only and will not run as is.   To run the script, you will need to install a number of supporting software applications.  You can review the readme file for additional information on using the sample clients.

What does NDFD XML contain?

NDFD XML contains forecasts for any combination of the following meteorological parameters:

http://www.nws.noaa.gov/ndfd/technical.htm#elements

For additional information on NDFD parameter definitions and available time projection, please see the NDFD technical page.

These NDFD parameters can be retrieved in their unsummarized form using the SOAP server functions NDFDgen() or NDFDgenZip(), or summarized over either 24- or 12-hourly periods using the functions NDFDgenByDay() or NDFDgenByDayZip. See the section below titled "How Do You Use the Web Service?" for more details on these two functions.

In addition to its meteorological content, NDFD XML contains meta data about the product.   A description of the meta data as well as data XML tags and attributes can be found in the Digital Weather Markup Language Specification [PDF] [HTML] [DOC]

A list of all possible fields for icons and the weather conditions in summarized form can be found at NDFD Web Service's Icon/Weather Conditions XML fields.

How Do You Use the Web Service?

The first step to using the web service is to create a SOAP client.   The client creates and sends the SOAP request to the server.   The request sent by the client then invokes one of the server functions.   There are currently nine functions: NDFDgen(), NDFDgenLatLonList(), LatLonListSubgrid(), LatLonListLine(), LatLonListZipCode(), LatLonListSquare(), CornerPoints(), NDFDgenByDay(), and NDFDgenByDayLatLonList().   See the tables below for required following user supplied input:

GML is an Open Geospatial Consortium standard for encoding geospatial data. One of the advantages of NDFD GML is that it is a recognized standard. As a result, GML and application schema derived from it are supported by a number of GIS applications. There are examples of importing GML-encoded NDFD data into several applications at the following link.

Once the SOAP server returns the XML document back to the client, you can then parse the DWML using SAX, the DOM, or XSLT.

All latitude and longitude values provided as input or in the output DWML are based on the World Geodetic System 1984 (WGS84). For more inforation on the NDFD spatial reference system see the NDFD Spatial Reference System page.

Please note: There is an NDFD Web Services user forum that might be able to help developers with implementation language specific issues. The unofficial forum can be found at the following URL:

http://tech.groups.yahoo.com/group/NDFD_SOAP_Service/

What if I need lots of NDFD data or find the web service too slow?

You should consult the NDFD web services use guidelines.

The NWS has developed a program called degrib that can output NDFD data encoded in DWML. Degrib is a C program that allows you to visualize NDFD GRIB2 data and convert these binary files into other formats. If you are a web service user who wants DWML-encoded data for a large number of NDFD points, degrib will allow you to move the DWML-encoding process to your computer. By using degrib to process the NDFD data on a local computer, you may be able to significantly improve the speed with which your program is able to ingest NDFD data. The NWS makes a degrib executable available for Microsoft Windows PCs and the degrib source code available for compilation on other computer operating systems. To download degrib software, visit the URL http://www.nws.noaa.gov/mdl/degrib/register.php. Once you have the degrib software running, you will need to maintain updated NDFD GRIB2 files. For more information on downloading NDFD GRIB2 files from the NWS Telecommunication Operations Center, see the URL http://www.nws.noaa.gov/mdl/degrib/dataloc.php. For additional help on using degrib to convert NDFD GRIB2 files into DWML see the degrib tutorial and man page.
