Synoptic’s Mesonet API is an expansive geophysical database of both historical and real-time surface-based weather observations from over 75,000 public and private observing stations, creating upwards of 34 million observations available to you, the user. This REST API is a request-based data delivery service using a simple HTTP call that can extract minutes or years of data in seconds for locations across the globe. The API allows for complete customization via the API call. A user can request specific variables at any time for an exact location anywhere on the globe. Need to find all stations within a certain radius? The API can do that too!

There are a multitude of API services. Below is a quick introduction to those that are most widely used. To learn more and get access to the API, click on the Get Started button below.
