Hi Charly I would be very interested in how these observations were made. I am not a smart doctoral candidate but as 'other people' my theory for this observation is the large increase in propagated noise floor we experience due to our proximity to the ITCZ.

There is over twenty years of observation of the absorption (?) of
incoming HF signals in a latitude band of about 25 degrees width
and seemingly along the MAGNETIC equator.
Consistently, signals coming in to this area are attenuated or lower than
reported outgoing far-field (2 to 4+ hops) signals. IN the geographical
area, stations hear worse than they are heard.
Could some smart doctoral candidate or other people get on this phenomena
with measured research and scientific explanation.
The area I know about stretches from VU4, over HS/XU/3W, and includes
Manila. Help? 73,
