Verification of results of rainfall intensity estimation formula R(KDP). Comparison with raingauges placed on a straight line in a westerly direction from the radar. They match extremely well.

Verification for 1-hour accumulated rainfall obtained by four rainfall estimation methods.
(a) R(ZH) method before rain attenuation correction.
(b) R(ZH) method after rain attenuation correction.
(c) R(KDP) and R(ZH) method before rain attenuation correction.
(d) R(KDP) and R(ZH) method after rain attenuation correction.
