Pictures from Taiwan Site Survey
Here are some pictures I took during my recent trip to Taiwan. Of particular interest will be pictures from the survey of potential S-Pol sites, which you will find about halfway through the album.

S-Pol Blockage Simulations for Taiwan
Here are blockage pattern simulation results for the two proposed TiMREX S-Pol sites, Air Force Academy and Levee. AFA has less blockage overall, but Levee has a nice view up the river valley. Both blockage patterns are much worse than anything we saw in NAME. It may be difficult to perform QPE in the eastern sector, beyond about 50 km range.
AFA 0.5-deg Elevation
AFA 1.0-deg Elevation
AFA 1.5-deg Elevation
AFA 2.0-deg Elevation
AFA 2.5-deg Elevation
AFA 3.0-deg Elevation
Levee 0.5-deg Elevation
Levee 1.0-deg Elevation
Levee 1.5-deg Elevation
Levee 2.0-deg Elevation
Levee 2.5-deg Elevation
Levee 3.0-deg Elevation
Levee 3.5-deg Elevation
Levee 4.0-deg Elevation
Levee 4.5-deg Elevation

RHI Sector Gridding Test
In TiMREX, S-Pol will likely scan RHI sectors on a regular basis. I tested the feasibility of using REORDER to grid RHI sector scans, similar to how we usually do with PPI sectors. The test was successful, with the RHI sectors gridding with few artifacts. Here are some examples using CHILL data from a hailstorm on 10 May 2005.
