Weather observations from the past
Weather History API provides observational weather information from the past by showing measured weather parameters in a certain location at a specific date.
The API delivers all the measured weather parameters as both daily summary values and hourly values. The queries can be made based on a given day and coordinate point. The API will respond with observational data from the nearest relevant weather station or from weather forecast model data (augmented observation) in JSON format. Augmented observations are provided when the closest weather station with sufficient observations is too far away to give representative information.
The weather history service includes measurements from the following official weather stations.
Weather Parameters Available
Mouse over the text codes to see the explanation. Pictures are provided only for some of the codes and nonsensical combinations don't even have standard text descriptions. The forecast symbols can also be mapped by Foreca to any subset of the provided symbols. We suggest only using the ones with pictures provided in any end-user services.
The following parameters are available in one-hour time steps.
Daily Summary Parameters
The daily summary parameters, the average, minimum and maximum values are based on the hourly observations of the day.
Data feed of the governmental severe weather warnings
The Foreca WarningFeed integrates weather warnings from many national warning systems worldwide and presents them in a harmonized global offering. The feed is an additional module that can be activated for Foreca Weather API, Weather File Feed accounts or delivered as GeoJSON files.
When queried with coordinates, Foreca Warning feed returns a sorted list of active warnings for the given location by importance. For each event, the WarningFeed provides the generic significance level, generic warning class, and a more detailed event description. The original data from the official sources is also included. The generic codes developed by Foreca are meant to ease visualising the end-user services, while the event descriptions provide more specific textual information.
