Upper atmosphere X-ray emission measurements in 3-31 keV range registered by the RPS-1 device on board the CORONAS-F
while in the Earth's shadow. The figures show 6-level intensity maps of the Earth in 4 X-ray energy ranges covering
the period from March 2002 to March 2004. One can see that all of the Earth's atmosphere emits in the soft X-range
(3-8 keV). In the hard X-range (8-31 keV) emission is absent in the medium latitudes, while the Brazilian magnetic anomaly
is clearly identified as well as the Earth's extrenal radiation belt. Gaps on the 2003-2004 maps are
due to lack of reliable data for these regions. Comparing the maps one can conclude that X-ray emission from the
radiation belts in 2003-2004 is higher than it was in 2002-2003.
