What is the gridded data used in weather?
Gridded data is a combination of point data (meaning data from a single, specific source such as an individual weather station) and other data sources that represent a large area of geography such as a 30 km by 30 km square. Weather data for a given latitude/longitude is returned for the grid cell where the lat/long is contained.
The Weather Company (TWC) uses many different sources of data in their gridded products including:
- Public weather stations, NOAA sources, and METAR stations
- Weather stations from their subsidiary, Weather Underground, that have passed a rigorous certification (gold star stations) are used in temperature calculations
- Additional radar interpolations
- Other factors that TWC does not reveal
