英文摘要: The diurnal variation of height-distributed nitric oxide (NO) radiative emission during November 2004 superstorm is studied using TIMED-SABER satellite observations over 55°N–55°S geographic latitude region. The NO volume emission rate (VER), both during day and nighttime, shows an equatorial movement with descending peak emission altitude as one moves toward the equator. The NO VER from altitude of 100 to 280 km is integrated in steps of 30 km above 160 km (and from 100 to 160 km), obtaining the NO infrared radiative flux (IRF). The response of NO IRF depends on the altitude and time of consideration. The NO IRF in the lower altitude (<190 km) shows higher enhancement and a slower recovery as compared to altitude above it. It is observed that NO IRF during day and night responds differently to the November 2004 superstorm. The zonally averaged daytime NO IRF is mainly highest during weaker main phase (10 November, Dst =−263 nT). The maximum zonally averaged nighttime NO IRF is observed during stronger main phase (8 November, Dst =−374 nT) for all altitudes. The maximum relative daytime (RDE) and nighttime enhancement (RNE), which represent the relative variation of NO IRF during storm periods as compared to quiet time value, also exhibit different variations during this storm period. The minimum RDE is observed to show an equatorial movement as one moves downward in altitude. The minimum RDE occurs at about 35°N–40°N for 250–280 km, which decreases toward the equator, and minimum RDE is found near the equator for 100–160 km. The minimum of RNE is observed over the equator for all altitudes. ©2018. American Geophysical Union. All Rights Reserved. Citation statistics:
