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.
WDB is a weather data storage system for storage of weather and water observations, forecasts, analysis fields, and models. The system should be compatible with the meteorological standards BUFR and GRIB (version 1 and 2). In addition to generic loading programs, WDB also features a flexible retrieval interface for retrieving weather data in time series or entire fields. WDB is built using PostgreSQL extended with PostGIS.
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.
