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 station
• latest_radar: Read latest NWS regional or ConUS radar mosaics as a stars object
• latest_ridge: Read latest NWS ridge as a stars object
• scale_fill_rradar: Continuous fill scale for use with NWS raster radar data
• stations: NOAA U.S. Radar Stations
