WebField-aligned irregularity (FAI) in the E region is also observed by Very High Frequency (VHF) radar in mid-latitude regions. FAI frequently occurs after sunset in summer hemispheres, and spectrum features of E region FAI echoes suggest that type-2 irregularity is dominant in the nighttime ionosphere.

WebIPP’s has resulted in an irregularity far larger being mapped as though it applied to a 500km disk. Maximum angle limitation Since we want to characterize isolated regions surrounded by quiet ionosphere, we instead need to make sure that the whole region around our unobserved region is well covered. The goal was to find a parameter that …
