NDFD Web Service's Icon/Weather Conditions XML fields


Below is a list of all possible fields for the NDFD Web Service's Icons.

For DWML, these field values are in the <conditions-icon> child element

For TSML, these field values are in the <CategoryList> child element


In the NDFD Web Service’s 12 hourly and 24 hourly summary products:

For DWML, the <weather-conditions> element (a child element of the
<weather> element) can have the attribute "weather-summary".

For TSML, for the weather parameter, the <gml:valueComponent> element
has the attribute xlink:title="Weather Summary".

In the NDFD Web Service’s time-series and glance products there is no weather summary. However, for all four products, the weather can be broken up into components.

For DWML, under the <weather-conditions> element, a child element <value> can exist if there is active weather occurring. Subsequent attributes of the <value> element are:


Here is an example:

<weather-conditions weather-summary="Rain/Sleet Likely">
  <value coverage="likely" intensity="light" weather-type="rain" qualifier="none"/>
  <value coverage="likely" intensity="light" additive="and" weather-type="snow" qualifier="none"/>
  <value coverage="likely" intensity="light" additive="and" weather-type="ice pellets"    qualifier="none"/>

For TSML, the weather components will be found in the <gml:valueComponent> element's attribute. They include:

xlink:title="Weather-Coverage (#)"
xlink:title="Weather-Type (#)"
xlink:title="Weather-Qualifier (#)"
xlink:title="Weather-Additive (#)"

Below is a list of all possible options for the five attributes for weather's "coverage", "intensity", "weather-type", "additive", and "qualifier" (NOTE, only the field values apply to TSML, as the schema, currently, is less stringent than DWML's):


<xsd:attribute name="coverage" use="optional">
  <xsd:restriction base="xsd:string">

  <xsd:attribute name="additive" use="optional">
  <xsd:restriction base="xsd:string">
  <xsd:enumeration value="and"/>
  <xsd:enumeration value="or"/>


<xsd:attribute name="qualifier" use="optional">
  <xsd:restriction base="xsd:string">
  <xsd:pattern value="(\p{L}* ?\p{L}*)?(,\p{L}+ ?\p{L}*)*"/>
