利用COSMIC小型电离层光度计测量的135.6 nm夜气辉辐射强度数据，反演得到峰值电子密度，并与地基垂测仪的观测结果进行比对。结果表明，受到来自130.4 nm波段和长波（近紫外至可见）波段杂散光的影响，电离层光度计测得的135.6 nm夜气辉辐射强度数据须进行带外杂散光修正，修正后的数据反演得到的峰值电子与垂测仪观测结果有较好一致性。
The peak electron density of the 135.6 nm nightglow radiation data by COSMIC tiny ionospheric photometer measurement is retrieved. The peak electron density values from the tiny ionospheric photometer and the ionosonde observation are compared. The results show that the 135.6 nm nightglow radiative intensity values must be revised to suppress the influences of the 130.4 nm band and the near ultraviolet upto visible wavelength radiation. The retrieval results from the revised data have good consistency.
