WGOVCWC(SID) queries the XML Feeds of Current Weather Conditions as
provided by NOAA's National Weather Service (http://www.weather.gov), and
returns a struct containing current weather conditions for the area
specified by the corresponding four char SID(s) (Station ID(s)).
Data is available only for a limited number (about 1,800) of locations
across the United States and U.S. Territories. To determine the four char
Station ID(s) of the relevant location(s) and for more information, visit
http://www.weather.gov/data/current_obs/.
The input argument SID can be a single Station ID, or a char or cell
array of Station IDs.
Data is acquired in XML format, after which it is converted into a struct
using the xml_parse function. This function is available in the XML
Toolbox by Marc Molinari on the MATLAB Central File Exchange (File ID
4278).
EXAMPLES:
Example 1: Using a single SID.
wgovcwc('KNYC') returns a 1x1 struct containing fields (among others):
location: 'New York City, Central Park, NY'
observation_time: 'Last Updated on Mar 13, 5:51 pm EST'
weather: 'Fair with Haze'
temp_f: 57
relative_humidity: 78
Example 2: Using a char array of three SIDS.
wgovcwc(['KNYC';'KJFK';'KHPN']) returns a 3x1 struct.
Example 3: Using a cell array of three SIDs.
wgovcwc({'KNYC';'KJFK';'KHPN'}) returns a 3x1 struct.
