Abstract:
We investigate the relationship between NO infrared radiation and x-ray radiation at different local time (LT) and latitudes of NO average fluxes.

The NO volume emission rates obtained by SABER instrument on board TIMED satellite and x-ray fluxes on long (0.1-0.8 nm) and short (0.05-0.4) channels measured by GOES 12 satellite were used. NO rates were vertically integrated to obtain fluxes, which are then separated into day (8<LT<16) and night (20<LT<4) LT sectors and averaged per 16 latitude bins each 10° wide.

The cross-correlation (CC) analysis between NO, for different latitude bins and LTs, and x-ray fluxes is performed. We found that x-ray fluxes are better correlated with NO at lower latitudes and during the day. Also, long x-ray fluxes are better correlated with NO than short ones. CC coefficients are maximal for both positive and negative time lags, depending on the latitude bin and LT span.
