E and F layer H.F. volume backscatter reflectivities
Abstract
H.F. radar backscatter data from an OTH radar site in northern Maine have been processed to produce estimates of E and F layer volume backscatter reflectivities. Nighttime returns were selected from the months of September and October and were sorted into evening and midnight time segments for active and quiet days. The reflectivities were analyzed for dependence on geomagnetic coordinates, as well as for dependence on frequency and auroral conditions. The frequency dependence through the 8-19 MHz range was very strong, while no clear geomagnetic correlation could be established.
