V6 Prototype Experimental Build: The next-generation of WSV3 looms on the horizon.

See video, "WSV3 founder Paul Maravelias narrates visual update on March 2023 V6.0 development progress." (March 30th, 2023)

"WSV3 V6 Prototype", an experimental concept build in development since October 2022, is a recontemplation and thorough re-engineering of WSV3 as high-performance Windows PC weather graphics software. Progress on this new, groundbreaking geospatial display engine for WSV3 was made available in May 2023 as an experimental build. This work will be continued in a next-generation WSV3 replacement product slated for late 2025. The experimental build remains available to all current WSV3 Professional users and can remain installed along with the release version as separate applications.

"WSV3 envisions an interactive weather graphics tool highly practical yet beautiful, one which dignifies the skillful work of a meteorological analyst with pristine and crisp graphics, transgressing neither the extreme of garishly overblown "tackiness" of visual style, nor of antiquated, bland, two-dimensional digital maps and charts.

We believe the visual appearance of an optimal weather data visualization and analysis program should preserve an evident correspondence to original numerical data, for scientific robustness, yet also promote an instictual perceptive clarity of thought process for the atmospheric analyst user, through performant, fluid, and dynamic graphics.

Such an application must necessarily reject conventional, high-level, CPU-based map/globe rendering and insist on state-of-the-art GPU-based real-time rendering techniques. It must implement a high-performance rendering pipeline on-par with those developed for AAA blockbuster video game console titles, to achieve smooth 60 FPS framerate on consumer-grade hardware. It must use high-efficiency, old-fashioned, native software design, challenging and defying the prevailing modern software culture of heavy, inefficient, non-native web browser applications."

Modern Product for Modern Hardware

WSV3's dynamic 3D GIS mapping system is one of only a few in the world to ingest and style ESRI Shapefile data at the user's configuration and display it with hardware-accelerated, fluid graphics - delivering precise weather graphics animations on consumer graphics hardware. Built-in street level mapping, road sign labeling, and standard GIS layers give users and viewers a crystal clear sense of weather and geographical space. Old, sluggish WeatherStudio has been blown out of the water.

Lightning-fast Server-backed Data

Many WSV3 data layers are backed by our new (2021) high-performance cloud-based imagery streaming service. You don't have to pay extra for this; it's built-in. E.g., for basic satellite imagery layers, beautiful high-resolution GOES-R imagery loops download an order of magnitude faster than direct client-side raw government data access. You'll be shocked by the speed. We also offer an optional extended add-on data service for expert analysts with a full suite of 128 live, operational GOES-R channels. WSV3 comes built-in with a generous selection of 3 private-server-hosted quality controlled MRMS-based National Radar mosaics and 8 GOES-16 CONUS imagery products, all fully loopable, including two unprecedented real-time GPU multispectral RGB products. WSV3 is the only Windows weather graphics software in the world delivering live-updating temporally interpolated multispectral GOES-R colorized RGB products using smooth, performant GPU rendering.

Quality Engineered for High-Performance

WSV3 employs a single, unified timeline system that links together, synchronizes, and smoothly animates all loaded data layers. No more confusing management of loading/freeing different loop layers and trying to keep them all synchronized. Our state-of-the-art graphics technology can display 10 times as much vector and raster data as WeatherStudio - faster. A fine-tuned, multi-threaded raster data system joins an industrial-grade vector graphics layer to bring TV broadcast quality graphics to any standard consumer PC.

A Partial Overview of Included Data

Long story short, WSV3 has it all.
We're also taking over the PC radar-software market by including a world-class NEXRAD Level 2/3 radar data viewer.

Fast-downloading, animated GOES Satellite imagery.

With choices between 8 imagery products, automatic synch linkage into WSV3's unified animated timeline, and lightning-fast pre-cached retrieval from our servers, getting a big picture of the weather through satellite data is a whole lot better and easier than it was in WS.

A killer METAR display engine.

Nine separate parameters from over 8,000+ stations across the globe, fully animated on the main timeline, and with precise visual customization options. WSV3 can also temporally interpolate METAR values real-time in loops - an unprecedented feature.

Full suite of tropical tracking products.

WSV3 takes a huge stride ahead of WeatherStudio's sluggish, old Shapefile based tropical products. As as a raw ATCF data client, WSV3 displays troves of tropical system tracking information in a beautiful, totally redone graphical display.

Real-time, live radar

Our NEXRADPro Level 2 radar system contains the LiveScan™ and LiveComposite™ technologies that display moving, sub-ten-second-delay radar data for time-critical applications. You will find this capability nowhere else.

App Main Features

National Radar Composite. A super-duper, precip-typed one.

While WeatherStudio struggled to load a mere 12 frame, low-resolution national radar loop, WSV3's brand new raster data system enables fluid quality-controlled precip-typed radar composites to load off our cloud-backed servers in seconds, with virtually zero post-processing needed.

Temporal interpolation.

Virtually all of WSV3's data products can use our signature "time interpolation" feature which smoothly animates and displays interstitial frame values on the unified program timeline. Combined with a custom time slider bar, users can adjust map time down to the minute.

Advanced derived products

The NEXRADPro Level 2 radar section of WSV3 boasts an advanced super-resolution 0.5km x 0.5° grid of highly practial derived products such as estimated hail size (MEHS), Wind Shear/Rotation, Echo Tops (ET), thunderstorm gusts, severe hail probabilities (POSH), and more.

Model data, Mesoanalysis data, and way more.

WSV3 allows you to inspect every last single GRIB2 parameter (all fields, and all heights - usually hundreds of products available) of any standard NOAA NCEP operational weather forecast model. The model engine in WSV3 is fully customizable and extensible; default config files for GFS Hi-res, FV3, HRRR, HRRR 48-hr, NAM, NAM 3k, NBM, RAP, HiresW, etc. offer you instant, point-click, rapid-loading inspection of static or animated forecast model data parameters in their original projection without grainy downscaling or corrupting excess smoothing/compression.

Customization. Performance. Killer graphics on usual consumer hardware.

We learned with old WeatherStudio that users need customization options for getting the right look to serve their website, TV station, public info kiosk, or simple personal preferences. Customization options and clear personal/commercial licensing terms allow you to export clean, usable graphics and use them as you wish.

  • HD video capture/still image export system.
  • Placefile data import.
  • Powerful GIS engine with custom Shapefile line/polygon mapping data import.


WSV3 contains an earth-shattering NEXRAD Level 2 and 3 data viewer system accessed in the first tab of the new "Header" UI. It's like climbing up a NEXRAD Radar and plugging your laptop into it. Performance wise, it blows away the competitor. The Level 2 stream has always been offered in real-time, but consumer software never caught up to display it in such a way - until WSV3.


Unprecedented NEXRAD Level 2 radar technologies

WSV3's LiveScan™ and patent-pending LiveComposite™ technology deliver seconds-old radar data to serve the most time sensitive and demanding applications. Outside of WSV3, no other product in the world can offer such set-it-and-forget-it, real-time NEXRAD-originated surface reflectivity data using a special technique that saves the same valuable upper-level tilt scan info that gets thrown out by traditional radar displays.
