NOAA's National Weather Service XML service change notices

List of changes made to XML services offered by NOAA's National Weather Service

• Current Obs XML: Application of new schema
  As of June 2, 2009, a new current observation schema is in place, as originally noted in April of 2008. The new schema allows fields that contain no data to not to have to appear in the xml data files. This was done to bring the actual XML into compliance with the schema and also to support a large number of new fields that would be empty for many observation stations. As a result of this change, xml files are now available for marine buoy observation sites.
• XML Alerts: Seeking comments on experimental CAP 1.1 messages
  NWS is accepting comments through December 1, 2008 on experiemental enhanced feeds of NWS watch/warning and advisories in the CAP 1.1 format. These feeds feature more detailed pre-parsing of NWS products than previously available and also feature ATOM based index feeds. It is expected these feeds will replace the current feeds over the next 18 months.
• Current Obs XML: ZIP file collections of all observations available
  Complete collections of the RSS and XML current observation files are now available. These files contain all current files of the two types for those who wish to download all files at once. These are updated hourly, normally about 10 minutes past the hour.
• Current Obs XML: Marine and Surf obervations elements added to schema
  Effective April 16, 2008, the schema for the current observation feeds has been updated for to include marine and surf related items The updated XSD introduces 19 parameters related to marine and surf observations. These parameters will be included in XML observations when the data for each is available. The new parameters are: water temperature: water_temp_f (fahrenheit) and water_temp_c (celsius), wind and wind gusts (knots): wind_kt and wind_gust_kt, pressure tendency: pressure_tendency_mb (millibars) and pressure_tendency_in (inches of mercury), wave height: wave_height_m (meters) and wave_height_ft (feet), wave periods (seconds), dominant and average: dominant_period_sec and average_period_sec, mean wave direction: mean_wave_dir (16 point compass) and mean_wave_degrees (360 degrees), tide information (reported by some buoys): tide_ft (feet), wave steepness (ratio of wave height to wave length): steepness, water column height (reported by DART buoys): water_column_height (meters), surf height: surf_height_ft (feet), swell: swell_dir (16 point compass), swell_degrees (360 degrees) and swell_period (seconds)
• NDFD XML: National Digital Forecast Database Now Disseminates Real-time Mesoscale Analysis Data
  Effective January 15, 2008, the National Digital Forecast Database (NDFD) Simple Object Access Protocol (SOAP) and Web Feature Service (WFS) began disseminating Real-time Mesoscale Analysis (RTMA) data. SOAP and WFS users can find out more information about the six new RTMA elements at http://www.weather.gov/os/notification/tin06-24rtma_grids.txt. Additional information on how to access the new data through the SOAP service and WFS can be found at http://www.weather.gov/forecasts/xml/ and http://www.weather.gov/forecasts/xml/OGC_services/.
