Vaisala IRIS - Table 6 Data Types

Data : Display
Select Data:Display to show a list of valid display parameter options. The available choices
vary depending on the product type.
This parameter specifies from which data parameter the product is derived. For example, Z,
V, W, ZT, or ZDR. This information comes from the task associated with the product. Some
data parameters can be displayed in more than one way.
Table 6 Data Types
Data type Description
Ah, Av Integral attenuation for horizontal (H) and vertical (V) channels.
Azdr
Integral attenuation of ZDR (dB) format.
CSR
Doppler channel clutter-to-signal (CSR) ratio of dBT to -dBZ.
dBT, dBTh, dBTv, DBTr Total power.
dBZ
Clutter corrected reflectivity
dBZt
Uncorrected reflectivity
HCLASS
Hydrometeor classification
Estimated hydrometeor type in the precipitation area.
KDP
Specific dierential phase
An indicator of the rate of change of the phase dierence between
horizontally and vertically polarized pulses of the radar. A greater horizontal
shift results in a positive KDP value, and a greater vertical shift results in a
negative KDP value. Typical cause for a high KDP area is heavy rain.
LDRH, LDRV Linear Depolarization Ratio H to V (or V to H).
The ratio of cross-polar to co-polar reflectivity measured in dB.
LOG
Log receiver signal-to-noise ratio.
