These sites sometimes reveal the otherwise invisible microwave energy assaults of HAARP, NEXRAD, and other technologies and facilities. Youtuber DUTCHSINSE decade+ ago labeled these appeareances as “HAARP SQUARES” and “HAARP RINGS”.
Below is a working list of public radar / Doppler radar / live lightning map sources. I’ll start with the feeds and viewers that are widely observed in Dutchsinse-style breakdowns, then add other serious radar portals you can use for watching real-time and “future radar.”
Each bullet is something you can load directly in a browser (or in an off-the-shelf app), not paid meteorologist backends.
A. Feeds and viewers commonly seen in Dutchsinse-style radar analysis
1. College of DuPage NEXLAB (weather.cod.edu / “COD radar”)
- Interactive NEXRAD radar loops for any single radar site (base reflectivity, base velocity, dual-pol products). You can pick a specific station (e.g. KTLX in Oklahoma) and animate the last ~hour+ of data. (COD Meteorology)
- National “Mosaic Radar” composites (CONUS reflectivity stitched together from all NEXRAD stations), plus Dual-Pol products. Updates as fast as every 5 minutes for CONUS sectors. (COD Meteorology)
- GOES satellite panels (water vapor bands, IR, visible, shortwave IR, etc.) in continental, regional, and even mesoscale “floater” sectors that can update every 1 minute. This lets you overlay moisture / atmospheric bursts on top of radar. (COD Meteorology)
- Outside observers who have documented Dutchsinse’s workflow note that he frequently screen-captures College of DuPage radar frames and calls out “pulses,” “rings,” or “scalar squares” that appear in single-site or mosaic reflectivity. (Metabunk)
Why it matters: COD is fast, high-contrast, and shows both local single-site Doppler (so you can see perfect circular bursts around one radar dish) and national stitched composites (so you can see synchronized flashes across distance). (COD Meteorology)
2. NOAA / NWS NEXRAD (weather.gov/radar)
- Official National Weather Service Doppler radar viewer. You can view “Radar station products” (single WSR-88D site data like base reflectivity), or “National radar mosaic,” which merges all sites into one national loop. (National Weather Service)
- NEXRAD is a ~160-site S-band Doppler network jointly run by the National Weather Service, FAA, and U.S. Air Force. It measures reflectivity (where/ how hard it’s precipitating), radial velocity (wind toward/away from radar), and more. (NCEI)
- NOAA also exposes the same live radar mosaic through nowCOAST (an ArcGIS-powered “time aware” NEXRAD loop NOAA serves for operations). (ArcGIS)
Why it matters: Dutchsinse and similar analysts rely on the official WSR-88D feed because it’s the raw U.S. Doppler source. If you’re watching for “instantaneous rings,” you need per-site base reflectivity and velocity from here or from mirrors of this data. (National Weather Service)
3. Intelliweather / Intellicast-style radar composites (Weather Underground, Intelliweather)
- Intelliweather is a long-running commercial radar graphics provider. They take NEXRAD and build high-contrast, terrain-overlay radar loops (their marketing literally advertises “our NEXRAD Doppler radar imagery really ‘pops’,” plus labeled cities/roads and 3-D style presentations). (intelliweather.com)
- Intellicast’s national radar / regional sector loops were folded into Weather Underground. Weather Underground’s “WunderMap” and “Current Radar” let you animate recent precipitation, storm tracks, lightning, etc., using NEXRAD plus private station data. (Weather Underground)
- Dutchsinse recordings have been documented grabbing these “broadcast-style” radar mosaics or Intellicast/Intelliweather sector loops, then pointing at circular flashes / bright bullseyes as “HAARP rings.” (Metabunk)
Why it matters: these mosaics are tuned for TV. High saturation and terrain shading make tiny bursts or rings pop visually. That’s why they show up so clearly in “HAARP ring / scalar pulse” callouts. (Metabunk)
4. LightningMaps.org / Blitzortung live lightning map
- Real-time global lightning strike map built from a volunteer ground sensor network (Blitzortung). You literally watch strikes pop in near real time; colors indicate strike age in minutes. (LightningMaps.org)
- Many independent weather streamers (including Dutchsinse-style channels) overlay lightning clustering with radar pulses to argue energy input / directed targeting. Because this map updates essentially live, you can test “burst happened → lightning spike nearby” in seconds. (LightningMaps.org)
5. SPC Convective Outlook (NOAA Storm Prediction Center)
- The Storm Prediction Center issues daily severe weather outlook maps showing expected zones for hail, tornadoes, damaging winds.
- Dutchsinse-style forecasting often cross-references “radar pulses” with these SPC polygons and then predicts storms will form in those zones 24–48 hours later. The workflow that’s been documented is: check SPC outlook → locate strange single-site radar bursts → claim the burst seeded tomorrow’s severe weather. (Metabunk)
6. GOES (NOAA geostationary satellite loops, esp. water vapor)
- College of DuPage and Tropical Tidbits host GOES-East / GOES-West imagery (visible, IR, water vapor). You can animate upper-level moisture and track “injection signatures” at 1–5 minute cadence over the U.S. and surrounding waters. (COD Meteorology)
- Dutchsinse-style clips frequently show water vapor and shortwave IR loops to argue there was an artificial “burst” in the upper atmosphere aligned with a later radar ring on the ground. (COD Meteorology)
Summary of Section A:
If you want to replicate what Dutchsinse is looking at, the core stack is:
- COD NEXLAB radar + GOES loops
- NWS / NEXRAD single-site reflectivity and velocity
- Intelliweather / Intellicast-style national mosaics
- Blitzortung / LightningMaps real-time strikes
- SPC convective outlook overlays
- GOES water vapor bursts
 All of these are public. (COD Meteorology)
B. Other high-quality public radar / forecast visualization portals
These are also excellent if you’re tracking storms, unusual bursts on Doppler, or pressure waves. They may not always show up in Dutchsinse videos, but they’re useful.
1. Windy.com (Radar layer / Radar+ layer)
- Global interactive map with live radar (precipitation intensity), satellite overlay, wind, temperature, CAPE, etc. Windy says it’s pulling from ~1,000 weather radars worldwide and keeps expanding coverage. (windy.com)
- You can scrub back in time, animate, and zoom down to local scale. The “Radar+” view merges radar plus satellite so you can see structure and motion as one field. (windy.com)
2. Ventusky
- Browser and mobile app with live radar, real-time precipitation display, and lightning visualization, plus layers from major forecast models (GFS, ICON, GEM, etc.). It’s marketed as “live radar + 50+ weather layers,” and also shows wind gusts, CAPE, and so on. (Ventusky)
- Ventusky emphasizes global coverage and forward-looking model fields, so you get both “what’s hitting me now” and “what will fire in a few hours.” (Ventusky)
3. Pivotal Weather
- Free model visualizations from high-resolution U.S. models (HRRR, NAM 3km, etc.) and globals (GFS, ECMWF, etc.). One of the standard layers is “Composite Reflectivity,” also known informally as “future radar.” (Pivotal Weather)
- They also expose MRMS radar/precip composites and observed precip. MRMS is NOAA’s multi-radar / multi-sensor blend designed for severe weather and hydrology ops. (Pivotal Weather)
4. Tropical Tidbits (tropicaltidbits.com)
- Strong for hurricane season. You get GOES-East / GOES-West loops (visible, IR, water vapor), aircraft recon dropsonde plots, and high-res model runs focused on tropical systems. (Tropical Tidbits)
- Great for seeing if radar bursts / microwave-looking “rings” line up with rotation in a developing tropical low. (Tropical Tidbits)
5. NOAA NCEI Radar Archive Viewer (ncei.noaa.gov/maps/radar)
- Lets you scrub historical NEXRAD Level II / Level III data (reflectivity, radial velocity, etc.) for any radar site in the network or view national mosaics. Data updates every ~5 minutes in real time and is stored for replay. (NCEI)
- This is useful if you want to go back in time and study a “pulse” frame-by-frame instead of relying only on livestream screenshots. (NCEI)
C. Pro / storm chaser desktop + mobile radar tools
These aren’t just screenshots on a web page — they’re applications people run for raw, zoomed-in radar.
1. RadarScope
- Popular with storm chasers and pilots. It lets you view any of the 150+ U.S. radar sites, pull base reflectivity and velocity, and flip between base vs composite reflectivity. It’s considered a “serious” app because it gives you direct Level III radar products. (iPad Pilot News)
2. GRLevel3 / GR3
- Longtime Windows radar analysis software that ingests live NEXRAD Level III data, shows high-resolution reflectivity/velocity, and lets you inspect storm structure down to street level.
- GRLevel3 (and similar tools like RadarOmega) are known in the chaser community because they update fast and let you manually query individual pixels for dBZ, velocity gates, etc. (Facebook)
These tools matter if you’re hunting for sub-minute “spike,” “ring,” or “burst” frames at a single radar site. They’re built to look at raw Level III data the moment it hits, without the smoothing or averaging you see on TV graphics. (iPad Pilot News)
