On the Radar
Weather Modification, Inc. not only sells and services C-band, X-band, and S-band weather radar systems to clients around the world; we incorporate them into our own cloud seeding projects. Ranging from smaller mobile radar systems, to polarimetric Doppler research quality systems, we can meet radar needs for a wide range of customers.
Weather Radar Systems are a versatile tool for atmospheric assessment, with uses that include:
- Rainfall estimates
- Real-time cloud detection
- Speed and direction of cell motion
- Identifying precipitation location and intensity
New Single and Dual Polarized Radar Systems
Weather Modification, Inc., owns, operates, and sells new single pol and dual pol radar systems that utilize a solid state transmitters, digital receivers and antenna control systems. Configurable display software allows a wide variety of user-defined product display and analysis features.
Available antenna diameters include 3.5 meters, 4.2 meters, and 4.5 meters. Also available are new fiberglass radomes.
