Doppler radar clouds.
Abstract A remote sensing method is proposed for the retrievals of vertical profiles of ice cloud microphysical parameters from ground-based measurements of radar reflectivity and Doppler velocity with a vertically pointed cloud radar. This method relates time-averaged Doppler velocities (which are …
Profiling Doppler radars, especially mm-wavelength radars have the ability to both detect and penetrate clouds and thus, provide detailed information on cloud dynamics (Kollias et al., 2007a). When pointing vertically, the observed radar Doppler velocity V d is the sum of the V air and the reflectivity-weighted particle …The pulsed X- and Ka-band cloud radar systems MIRA-10 and MIRA-35 (formely named MIRA-36) are unique in performance and durability and deliver a calibrated Doppler spectrum of cloud droplets in up to 1024 height steps for a vertical range up to 15 km at a finest time resolution of 20 Hz (no coherent averaging). The wide …The EC-CPR will be the first spaceborne Doppler cloud radar used in climate research and evaluation of numerical weather prediction models (e.g., Kobayashi et al. 2002): its Doppler capability along with its high sensitivity (−35 dBZ or better) is a step forward in spaceborne millimeter-wave radars beyond the current state-of-the-art defined ...The Cloud Radar System (CRS) is a 94 GHz, W-band polarimetric Doppler radar designed to operate aboard the NASA ER-2 high-altitude research aircraft or as a ground-based radar.

The radar transmits a focused pulse of microwave energy (yup, just like a microwave oven or a cell phone, but stronger) at an object, most likely a cloud. Part of this beam of energy bounces back and is measured by the radar, providing information about the object. Radar can measure precipitation size, quantity, speed and direction of movement ...
Profiling, millimeter-wavelength (cloud) radars can provide such observations. In particular, the first three moments of the recorded cloud radar Doppler spectra, the radar reflectivity, mean Doppler velocity, and spectrum width, are often used to retrieve cloud microphysical and dynamical properties.Radar is a wonderful tool here on Earth. It is used by meteorologists to measure the speed of a storm and whether a tornado might be forming. It’s used to measure how fast our favorite baseball pitcher can throw a ball, and can even tell us if we really deserved that speeding ticket we got.

One each on Kauai and Molokai, and two on the Big Island of Hawaii. These dopplar radars give the National Weather Service Forecast Office in Honolulu both reflectivity and velocity data about storms affecting the area.Doppler radar has a detection range of ~400 kms. It can transmit information about a cloud, its distance from land, its composition, which direction it is moving and even minute details like the number and size of water droplets found in a cloud. We can predict the amount of rainfall to an area, 2-3 hours in advance.

Some of that energy is backscattered to the radar from the volume of scatters (raindrops, hailstones, insects, and so forth).
The NTDA is designed to routinely measure turbulence (eddy dissipation rate, EDR) in clouds and precipitation using ground-based Doppler weather radar data. The Doppler spectrum width (SW) represents the variability of the wind’s radial velocity—i.e., its speed toward or away from the radar—within the radar’s measurement volume.For example, ultrasonic anemometers are used for surface single-point measurement, and wind profile radars can detect changes in wind direction and …Note: It may take several dozen seconds to a few minutes to load the radar images onto the map.
