These data are checked for quality and accuracy and then redistributed to users. CWOP members send their weather data by to special computer servers (MADIS), and then every 15 minutes, the entire data set is sent from these servers to an NWS server. There are over 7,000 registered CWOP members world wide, including a large number in Kentucky, Indiana, and Ohio. So how do you get your weather data online? The Citizen Weather Observer Program (CWOP) is a private-public partnership with three main goals: 1) to collect weather data contributed by citizens 2) to make these data available for weather services and homeland security and 3) to provide feedback to the data contributors so that they have the tools to check and improve their data quality. If your weather station and accompanying computer software has this functionality (check the instruction manuals), and you have dedicated connection to the Internet, read on for some more information on how you can send your data out to the world! Posting your data online is relatively quick and simple if you own a weather station that is capable of interfacing with a computer. If you wish to access this disply, just follow the link above! Most of these are private weather stations! (Image courtesy of MADIS). In addition, have you ever watched the weather on television and your favorite meteorologist shows or references weather data from some pretty small towns and remote areas not near your typical larger airports that have a dedicated weather sensor? That data comes from personal weather stations, uploaded to the MADIS data stream, and used by television meteorologists to help bring local weather conditions to you, the viewer.Ĭheck out the screen capture below - all those dots represent weather stations that are sending data into the MADIS data stream. Own a Weather Station? We Want Your Data!ĭo you own a personal home weather station and a computer with a dedicated connection to the Internet, such as fiber, DSL or cable? If you do, the National Weather Service (NWS) and local television meteorologists would love to see your data! The NWS can ingest your frequently-posted weather data into our data and display systems, which can not only improve computer model data (and subsequent weather forecasts) for your area, but also makes the NWS and local television meteorologists aware of micro-climates (unique temperature, wind and precipitation patterns) specific to your local area.
