abstract:
This study shows the relation between CNA and energy
deposition by precipitating electron of more 10keV to lower
ionosphere. It was analized with CNA data observed with
Imaging Riometer at Poker Flat, Alaska and less 30keV
electron flux data simultaneously observed on DMSP when it's
conjugate point located at FOV of Imaging Riometer at
PokerFlat. The relationships of absorption A (db) and
incident electron energy P (W/m^2) was indicated as
P(10-30keV)=0.21*10^(-3)*A(38.2MHz)^1.16. The coefficients of
equationis different from the ones calculated theoretically
by Stoker (1993) and Penman et al. (1979), P=0.5*10^(-2)
*A(30.0MHz)^2.2 and P=0.5*10^(-2)*A(30.0MHz)^2.0.
