The scale of dBZ values can be seen along the bottom of the image. dBZ is a logarithmic dimensionless technical unit used in radar.It is mostly used in weather radar, to compare the equivalent reflectivity factor (Z) of a remote object (in mm 6 per m 3) to the return of a droplet of rain with a diameter of 1 mm (1 mm 6 per m 3).

MyRadar is a free weather forecasting application developed by Andy Green and his Orlando, Florida-based company ACME AtronOmatic (ACME). The app began operations in 2008 and ran on government-provided weather and radar data for its first decade. In 2019, ACME launched personal satellites to improve predictions of ongoing weather.
A NEXRAD weather radar currently used by the National Weather Service (NWS) is a 10 cm wavelength (2700-3000 MHz) radar capable of a complete scan every 4.5 to 10 minutes, depending on the number of angles scanned, and depending on whether or not MESO-SAILS [7] is active, which adds a supplemental low-level scan while completing a volume scan ...
In 2017, Weather Underground removed support for "Storm," in favor of the "Storm Radar" app released by The Weather Channel Interactive in June 2017. [32] On December 31, 2018, Weather Underground ceased offering its popular application programming interface (API) for weather data, further reducing the breadth of its services. [33]
The Radar Operations Center (ROC) is a National Weather Service (NWS) unit that coordinates the development, maintenance, and training for the NEXRAD weather radar network. [1]
Oregon has a wide range of temperatures, though the extremes are rare. [3] The highest was recorded on July 29, 1898, in Hermiston, Oregon, and again on August 10, 1898, in both Pendleton, Oregon and Redmond, Oregon, and once more on June 29, 2021, at Pelton Dam. All are east of the Cascades, when the temperature reached 119 °F (48 °C). [6]
