At the end of the script, results are also written to a CSV file in the results folder. If everything is operational (you need to import the wunderground-core JAR library), results should display in the console. The selected weather station ID, which can be obtained directly by browsing the wunderground website or by listing the available stations using the example code available from wunderground-core (or uncomment the corresponding code to display the full list).A vector giving the number of days in a month, that only needs to be edited to account for leap years (February with 28 or 29 days).The parameters of the script are the following (see WUndergroundHistoData.java) in the source code: Based on the examples provided at wunderground-core, I created the class available here. Data includes temperature, wind speed, humidity, rain rate, etc., but unfortunately not solar radiation. I used this API to build a Java class that retrieves historical data over a year from a specific weather station.
Martin Benning developed wunderground-core, a Java API for weather data handling from wunderground weather stations. In the following, I describe such a method. There is however no built-in functionality to retrieve historical data over long periods (e.g., a year), which means that you need to write a script, either using the API, or using another method. An API also exists for retrieving data from the service. Measurements from personal weather stations can also be uploaded to the website and be made available. Weather Underground ( wunderground) is a website that provides weather-related reports, forecasts, maps, etc. This Java class automatically retrieves weather data from wunderground.
