radar volume

radar volume

[′rā‚där ‚väl·yəm]
(electromagnetism)
The volume in space that is irradiated by a given radar; for a continuous-wave radar it is equivalent to the antenna radiation pattern; for a pulse radar it is a function of the cross-section area of the beam of the antenna and the pulse length of the transmitted pulse.

Meantime, as the duration of one cycle of radar volume scan is five minutes, the analysis time interval was also set to be five minutes.
The PID is designed to identify the most likely dominant scatterer in the radar volume. For example, large Z and near-zero or negative [Z.sub.DR] is a strong indicator of hail; however, if the hail is mixed with small ice or cloud drops, only the reflectivity-dominant hail will be detected.
By only using data from one or two nearby radars in an analysis, a large part of atmosphere located above the radar cannot be effectively observed due to the limits in the elevation of a radar volume scan, known as the "cone of silence".
The SW is an estimate of the variance of the radial velocities of the different particles within the radar volume. Sources of variance that contribute to SW for HCR include wind shear within the radar volume, different particle fall speeds, turbulence, and the motion of the platform.
For each radar volume scan with a positive tropical rain identification, all pixels within a predefined radius (default = 120 km) are identified as tropical rain if seamless hybrid scan reflectivity is relatively high ([greater than or equal to] 25 dBZ), surface temperature is warm ([greater than or equal to] 10[degrees]C), and the probability of warm rain (POWR; Grams et al.
