The Geostationary Operational Environmental Satellites (GOES) Data Collection Platforms (DCPs) are a set of hydrologic and meteorologic data collection points. The DCPs are a collection of networks owned and operated by a host of entities. [1] The IEM receives this dataset from our UNIDATA feed, which contains the products produced by the Office of Hydrological Development of the National Weather Service.
The NWS has a fantastic website if you are curious about this dataset.
