Responses of intermediate layers to geomagnetic activity during the 2009 deep solar minimum over the Brazilian low-latitude sector

Responses of intermediate layers to geomagnetic activity during the 2009 deep solar minimum over the Brazilian low-latitude sector

This work presents the daytime behavior of the intermediate layer (ILs) parameters (the virtual height - h'IL, and the top frequency - ftIL) over the low-latitude region of Cachoeria Paulista (CP, 22.42 ° S; 45 ° W, I: -34.59°) during the 2009 deep solar minimum. Under such a unique condition,...
