Mountain Pass Forecast The Mountain Pass Forecast allows customers to check the forecast for significant highway passes for the next three days. Passes were chosen for this product based upon the frequency of calls to the WFO concerning weather at the pass and potential for impacts to travelers and commerce.The forecast consists of a text product that can be accessed via a web page John Lovegrove 
Digital Wind and Wave Forecasts on Inland Lakes and Reservoirs Wind and wave digital forecasts on inland lakes and reservoirs in text and graphical forecasts on the WFO web page. Wind and wave forecasts created within the GFE using the NOAA/GLERL wind/wave model.WInd wave forecasts for the lakes are produced using forecaster derived data. John S. Eise 
National Digital Forecast Database Extensible Markup Language National Digital Forecast Database (NDFD) Extensible Markup Language (XML) is a service providing the public, government agencies, and commercial enterprises with user selected components for point locations of the National Weather Service?s (NWS) data embedded in XML elements. NDFD XML provides users the ability, using a machine-to-machine paradigm, to retrieve the XML-wrapped data via the Internet. This web service is provided using the SOAP protocol.... John Schattel 
Tactical Decision Aid The Tactical Decision Aid (TDA) web page for the Terminal Radar Approach Controller (TRACON) highlights forecasts of thunderstorm potential for the TRACON's aircraft arrival corner posts. These forecasts will be updated hourly during periods of convective weather (occurring or forecast) and every four hours during periods of no convective weather. Forecasts will cover a 4 hour time frame. Forecast output will be a color-coded, bar graph indicating the hourly probability of thunderstorm activity at each corner post during the upcoming 4 hour period. John Werth 
Real Time US Total Electron Content Vertical and Slant The US Total Electron Content (US-TEC) product is designed to specify TEC over the Continental US (CONUS) in near real time. The product uses a Kalman Filter data assimilation technique driven by data from ground-based Global Positioning System (GPS) dual frequency receivers. The primary data stream comes from the Maritime and Nationwide Differential GPS (M/NDGPS) real time network of stations operated by the US Coast Guard (USCG). As of Oct 2004 there were about 60 M/NDGPS stations ingested into the model. This number has been gradually increasing and will be augmented by Federal Aviation Administration/Wide Area Augmentation System (FAA/WAAS) data, and stations operated by the Forecast System Laboratory (FSL). This product has evolved from collaboration among Space Environment Center (SEC), National Geodetic Survey (NGS), National Geophysical Data Center (NGDC), and FSL. Joseph Kunches 
Lightning Strike Density Product The Lightning Strike Density product is a gridded and graphical depiction of the density of lightning strikes. Units for the gridded product (GRIB2) as per WMO requirement are in SI units and are (number of strikes) m-2 sec-1 . These units require a scaling factor of 10 11 (11 is an exponent) to convert to km-2 min-1. The gridded forms are written to 8 km x8 km resolution and are generated in 15 and 30 min collectives. The lightning strike density product is based on the ground based Vaisala GLD360 global lightning network and is capable of detecting cloud-to-ground strokes, cloud-to-ground flash information and survey level cloud lightning information. Lightning Strike Density, as opposed to display of individual strikes, highlights the location of lightning cores and trends of increasing and decreasing activity. It is also a parameter that is useful to compare cloud to ground capabilities from different sources of lightning data. Joseph Sienkiewicz 
Standardized WFO, Regional, and National Climate Web Pages Once implemented, this standardization of climate information (regarding what type is provided and where it?s located on NWS Web pages) will enable our users to consistently find climate data no matter which NWS level (WFO, regional, or national) they access via the Web. Judith Koepsell 
Multimedia Weather Briefing The Multimedia Weather Briefing is an Internet-accessible multimedia file that provides information concerning hazardous weather events within the service area of a Southern Region office. The briefing provides a medium for supporting the planning activities of emergency response partners and customers by conveying (both aurally and visually, in non-technical terms) the forecaster's reasoning and confidence concerning upcoming hazardous weather events.

NOAA Weather Radio Podcasts The NWS is responsible for making its weather, water and climate information widely available to taxpayers using commonly accepted standards and technologies. Currently, the NWS provides only limited audio broadcasts of their NOAA Weather Radio All Hazards (NWR) via the Internet. The Voice Improvement Program (VIP) software on the NWR is able to convert the text transmitted to the Console Replacement System (CRS) into MPEG audio Layer-3 (MP3) files. Southern Region NWS offices are making these MP3 files available on the Internet as podcasts. Podcasting allows for publishing of audio programs to the internet and subsequent downloading of these programs to a personal computer or MP3 device. Users subscribe to the NWR podcast by using a freely available podcasting application that downloads the MP3 file automatically using an RSS (Really Simple Syndication) feed. Podcasting applications typically check for new content (new MP3 files) at user defined intervals. Once downloaded, the user can then listen to the podcast at his/her leisure (versus a radio broadcast of NWR). Judson Ladd 
Crosswind Calculator Aid The Crosswind Decision Aid is color-coded according to the degree of impact the wind will have on various runways green indicating little or no impact; yellow indicating marginal impact; and red indicating significant impact. Each color level is triggered based on a user-defined wind direction and wind speed threshold. The product also includes a Wet Runway/IFR factor that effectively lowers the crosswind speed thresholds. Judson Ladd 
HotSeat Warning Simulator HotSeat is a web-based warning simulation tool. It uses archived WSR-88D data from actual events along with severe weather reports and damage survey photographs in a displaced real-time (DRT) mode to approximate the feel of issuing severe weather warnings in the National Weather Service. Upon completion of each event, the participant receives a score indicating his/her success in the simulation. Judson Ladd 
Tactical Convective Hazard Product (TCHP) The TCHP provides a graphical presentation of thunderstorm hazards to aviation operations. It depicts current hazardous thunderstorms and a one-hour forecast of hazardous thunderstorm locations. The TCHP updates automatically every 5 minutes. The product is created from radar and lightning data as well as human-generated Convective SIGMET in-flight advisories (SIGMETs updated hourly). Judson Ladd
