AB: Broadband limb measurements have been used extensively for sounding the upper atmosphere, providing excellent vertical resolution and high precision of temperature and key atmospheric constituents. Emission sensors can provide daily global maps, while occultation sensors are suited to less coverage but produce sensitive and reliable trends over years and even decades. Traditionally these sensors have relied on ground calibration to ensure that spectral out-of-band (OOB) response is either negligible or accurately modeled in the operational analysis. There are indications that these unknown effects are not always negligible. Recent analyses of measurements from an occultation experiment, HALOE (HALogen Occultation Experiment), and an emission experiment, SABER (Sounding of the Atmosphere using Broadband Emission Radiometry), were performed to test the validity of the OOB ground calibration for these two instruments. The results of these studies, including simulations, and corrections are presented, along with suggested design criteria and tests for current and future sensors.
