Products on Mac – Product Legend

The product legend sits immediately above the map and below the toolbar. It provides the means for selecting radar products to view and information about the currently displayed data.

Product Menu

The name of the currently selected product appears in a button on the left side the product legend. RadarScope provides a full suite of radar products to view. Clicking the product name reveals a menu of available products. Click and drag through the menu to select the desired product to load and display the data. Some products are available at multiple tilts or beam angles. To change the tilt of the selected product, click the Tilt button to the right of the product name and choose the desired tilt.

Product Time

The product time stamp appears on the right side of the product legend. This number indicates the time at which the currently displayed radar product was observed. The time is always displayed according to your device’s current local time zone as specified in your device settings, even when you’re watching a radar in a different time zone. RadarScope Pro Tier 2 offers a 30-day archive of radar products. When the archive is available, a gray disclosure arrow will appear next to the product time. To view archived data, click the disclosure arrow to reveal the archive date picker. Learn more about displaying archived data in the RadarScope Pro section.


Product details appear below the product name and time. For most radial products, the beam elevation angle is displayed below the product name. For certain precipitation estimate products, the starting time of the accumulation period is shown instead. The time shown below the product time indicates the when RadarScope last refreshed the data. Radar products update every 1 to 10 minutes, so this time doesn’t always match the product time. For example, if the product time is 1:00 PM and the update time is 1:03 PM, that indicates RadarScope checked for an update at 1:03 PM and the 1:00 PM data was the most recent available. When radar data don’t refresh as quickly as expected the product time and update time will be displayed in red to indicate that the data are older than expected. This error may occur when a radar goes offline for maintenance or repairs, when a communication link goes down, or due to a temporary issue with the data provider.

Color Bar

The color bar below the map indicates the color scale of the currently displayed radar product. Each color in the scale is associated with a value in the radar data. Position the mouse cursor in the color bar to reveal a popup showing the color and its associated value, then drag across the color bar to see the range of values.
