metaf2xml can download, parse, and decode aviation routine weather reports (METAR, SPECI, SAO), aerodrome forecasts (TAF), synoptic observations (SYNOP), and BUOY observations, and store the data as XML. XSLT style sheets convert it to plain language, as HTML or text. Current weather data from NOAA and other sources can be fetched and displayed.
AWeather is a real-time weather data viewer designed for weather enthusiasts. AWeather is not a weather widget/dockapp that displays a pre-computed forecast. It is designed to be an easy to use program that integrates a variety of meteorological data in a simple unified interface. Currently, AWeather only displays data provided by the United States National Weather Service.
OwfsWeather is a package that scans and logs weather data from various One-Wire weather sensors. It uses OWFS, the One Wire File System, to communicate with the sensors. It currently supports logging of weather data to Weather Underground, a CSV file, and to an RRD database. Current hardware supported is the WSI-601 weather station from AAG, a DS1820 temperature sensor, and the humidity and barometric pressure modules from Hobby Boards.
wfrog is a Web-based weather station software with nice charts and many ways to publish them on the Web. The architecture is meant to make it very easy to add support for other weather station models and to allow for rendering the weather data in several formats and media using an extensible renderer structure. The processing and memory footprint of wfrog is very low, making it suitable to run on low-power equipment like PC-engine Alix, Cisco NLSU2, or SheevaPlug. The currently supported weather stations are Ambient Weather WS1080, Davis VantagePro, VantagePro2, Elecsa AstroTouch 6975, Fine Offset Electronics H1080, WH1081, WH1090, WH1091, WH2080, WH2081, Freetec PX1117, LaCrosse 2300 series, Oregon Scientific WMR100N, MR200, WMRS200, WMR928X, PCE FWS20, Scientific Sales Pro, Touch Screen Weather Station, Topcom National Geographic 265NE, Watson W8681, and any station using the WESTEP protocol.
