Radiowave extinction area:
It judges whether or not the returned reflected wave is worthy of evaluation and indicates the area
with undeserving by dual polarization parameter analysis.
Select the radio wave extinction (sector blanking) area.
OFF: No sector blanking displayed.
1: Blank sector indicates with gray color.
2: Blank sector indicates with transparent gray color (horizontal data only, it will not be transparent
on SRHI).
[Note: Setting file (Clip_RainMap.csv in param folder) is necessary]
[Brief explanation]
About shielding area:
There may be some areas where mountains or other obstructions are blocking the radio wave of
radar. RainMap indicates those areas with a gray color.
First the "Clip_RainMap.csv" file that describes the grayed out area must be created.
Refer to quality information of observing data about scn format in section 7.3 for detail of shielding
area.
About antenna rotation:
Basically the antenna is rotating clockwise based on
the azimuth origin during PPI and Volume scan as
shown in Figure 2.1.
