Live Infrared & Visible Cloud Satellite — California
The California Cloud Cover Satellite provides visible and infrared atmospheric imagery showing cloud layer ceiling, fog formation, and overcast coverage over {state}. Track cloud cover density, ceiling altitude, and marine fog layers across California with live infrared satellite radar scans. Data updates every 5 to 10 minutes from NOAA & NWS dual-polarization Doppler stations.
NWS Radar Station Infrastructure (California)
Radar surveillance across California relies on National Weather Service (NWS) NEXRAD WSR-88D Doppler stations including **KVTX** (Los Angeles / Oxnard Radar in Oxnard), **KMUX** (San Francisco Bay Area Radar in San Jose), **KNKX** (San Diego Radar in Miramar), **KDAX** (Sacramento Radar in Davis), **KHNX** (San Joaquin Valley Radar in Hanford). These high-frequency microwave radar sites transmit pulsed radio beams every 4.5 to 10 minutes, generating real-time base reflectivity scans.
Active Station Callsigns
How to Read Cloud Cover Scale
Indicates light rain or atmospheric drizzle that usually does not impede travel.
Represents steady, moderate rainfall. Roads may experience pooling and reduced visibility.
Indicates torrential downpours, severe convective thunderstorms, lightning, or potential hail cores.
Regional Climate & Atmospheric Context
California weather patterns feature atmospheric rivers, winter Pacific storm fronts, coastal fog marine layers, and Santa Ana offshore wind events impacting wildland-urban interfaces. Using S-band dual-polarization technology, radar pulses measure raindrop diameter and ice density to distinguish between light drizzle, torrential downpours, and hail.
