rradar
Animate NOAA NWSRadar Images by Station Id
Description
NOAA NWS has an array of National Doppler Radar Sites. Tools are provided to to help you locate stations and create an animated composite image of recent radar images.
What’s Inside The Tin
The following functions are implemented:
animate_conus_mosaic: Create an animated weather radar mosaic for the the conterminus U.S.animate_radar: Create an animated weather image from a NOAA stationlatest_radar: Read latest NWS regional or ConUS radar mosaics as a stars objectlatest_ridge: Read latest NWS ridge as a stars objectscale_fill_rradar: Continuous fill scale for use with NWS raster radar datastations: NOAA U.S. Radar Stations
