From: Post-sunset rise of equatorial F layer—or upwelling growth?
A sketch showing growth of an upwelling (red curve) over CPN, but not over BCL (red dashed line), at time t1, and the arrival of the same upwelling over BCL (green line) at time t2. In this sketch, we show (for simplicity) the absence of a PSSR over both CPN and BCL. The separation between CPN and BCL is 6.3° in longitude and 25.2 min in LST
