In addition to being able to see NEXRAD storm attributes (including storm tracks), users can also view rainfall estimates (in one-hour, three-hour, and storm total increments), composite reflectivity (which combines all radar sweeps into one image), as well as low-resolution dual-polarization data. The program uses Level III radar data, which has a much lower resolution than Level II data but comes with a few more products.

GRLevel3 is GR2A's less expensive and less powerful twin. It's a bit pricey at $250, but it's well worth it. The powerful features included in GR2A, along with its Landsat backgrounds and extreme level of customization, makes this program the best of the best. The result is a three-dimensional look at the storm, and the product is often extremely interesting (and useful in a forecast setting). The coolest feature in the program is the volume explorer, which takes into account all 13-15 radar sweeps and extrapolates the precipitation down between the layers. This is great for supercells and other storms of interest. GR2A also features a cross-section tool that lets you slice features in half and view their internal workings. The biggest feature that comes with GR2A is its ability to display super-resolution Level II radar data, which is a resolution four times higher than Level III data (which is what you commonly see). The software is what I use to post radar images here on The Vane, and GR2A is just as awesome as it is powerful. The program is so powerful that even the National Weather Service uses it as a supplement to their own suite of software.

GRLevel2 Analyst (or GR2A) is a program produced by Gibson Ridge, and it is the cream of the crop when it comes to weather radar programs. Let's take a look at the best (and the worst) weather radar programs. Trying to judge which one is the best can be tough, and each has its strengths and weaknesses. If you're a weather geek and have a few bucks to burn, there are quite a few excellent weather radar programs available for download.
