Radar & Satellite

The operational observation layer. Radar mosaics, high-resolution NEXRAD products, GOES sector views beyond the full-disk Earth View, and the specialty satellite products tropical and severe-weather forecasters actually reach for.

NWS National Radar

NOAA · Live national mosaic

National radar composite from 160+ NEXRAD sites, updated every 5 minutes. Storm-based warnings overlay automatically. Zoomable to individual radar stations, filterable by reflectivity, velocity, and precipitation products. The default radar reach for any active severe weather.

MRMS Composite

NSSL · Research-grade

Multi-Radar Multi-Sensor — the NOAA NSSL-developed mosaic that blends NEXRAD with satellite, lightning, and surface observations. Higher resolution and more product variety than the standard NWS radar. Where researchers and severe weather specialists go.

College of DuPage NEXLAB

Academic · Educational

The academic radar viewer forecasters cut their teeth on. Individual radar sites, regional mosaics, legacy-style display with every reflectivity and velocity product. NEXLAB is old-school in the best way — built by meteorologists, for meteorologists.

Today's Storm Reports

SPC · Live storm reports

Preliminary storm reports from the Storm Prediction Center — tornado touchdowns, hail, wind damage. The running ledger of what actually happened today, compiled from NWS offices and trained observers as the reports come in.

GOES-East Sectors

NOAA STAR · 75.2°W

CONUS, Gulf of Mexico, Caribbean, Tropical Atlantic, Northeast, Gulf of Alaska — every sector GOES-East covers, in GeoColor, water vapor, infrared, and RGB composite products. The Earth View disk is the wide shot; sectors are the zoom.

GOES-West Sectors

NOAA STAR · 137.2°W

Pacific Northwest, California, Hawaii, tropical Pacific, mesoscale sectors for individual storm systems. Paired with GOES-East, covers the Americas from Atlantic to mid-Pacific in finer detail than a full disk allows.

Specialty Channels

NOAA STAR · IR, water vapor, RGB

Upper-tropospheric water vapor for jet-stream analysis, infrared for nighttime convection, air mass RGB for weather-system identification, dust and sandstorm RGB, fire detection. What forecasters reach for when GeoColor isn't telling the story.

CIMSS Tropical

U. Wisconsin · Research-grade

Cooperative Institute for Meteorological Satellite Studies — the research group behind the satellite products NHC relies on. Tropical cyclone imagery, Dvorak analysis, microwave passes, wind shear diagnostics. Where tropical forecasters spend their mornings.

Continuous Launch CIMSS →

Radar and satellite products from the National Weather Service, NOAA National Severe Storms Lab, NOAA STAR, the Storm Prediction Center, College of DuPage (academic), and the University of Wisconsin CIMSS (academic research).
