@mapnerdalpha: This animation shows hourly surface air temperature across parts of North America for December 2022 and the first few days of January 2023. It was produced by combining satellite observations with temperatures calculated by a version of the Goddard Earth Observing System (GEOS) global model, which uses mathematical equations to represent physical processes in the atmosphere.
