F/sub 2/ peak electron densities in the main trough region of the ionosphere

Technical Report ·
OSTI ID:7216460
A study of the main trough in the F2 region was made using observations from Alouette I and II. Parameters needed to predict the occurrence of the trough were determined from the many observations. These parameters were used to develop a modification factor for use with C.E.I.R. model of predicted MmF2. This modification factor reduced the C.E.I.R. model predicted NmF2 to more representative values of MmF2 in the main trough region.
