Brief introduction of radar data

During TAHOPE, CWB supply raw radar data (Table 1) and processed radar data (Table 2).

Fig 1. shows the weather radar network in Taiwan.

For more information about the weather radar network in Taiwna, an article An Operational Multi-Radar Multi-Sensor QPE System in Taiwan is highly recommanded to read in detail.
