Radar refractivity
Utilizing the characteristic that the delay of radar waves reflected
from fixed objects such as transmission towers is dependent on water vapor and temperature,
the temporal cahnge of the refractivity between fixed objects was obtained
by taking the difference of delay from two fixed objects on the path of the radio wave.
Observed data: horizontal distribution of temporal change of refractivity
Observed region and period: Kanto region, from July to September 2019
