英文摘要 | We present a new atomic oxygen data set based on Scanning Imaging Absorption Spectrometer for Atmospheric CHartographY (SCIAMACHY) hydroxyl short-wave infrared data. The OH spectra stem from the OH(9-6) ro-vibrational transition. These data and atomic oxygen obtained from SCIAMACHY O(S-1) green line measurements, which is an independent data set in terms of methodology and radiometry, typically agree within 10-20%. This confirms the corresponding models of OH and O(S-1), in particular, the relevance of the reaction between atomic oxygen and ozone in the photochemical model. The agreement between the SCIAMACHY data and the most recent Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) atomic oxygen data set of Mlynczak et al. (2018, ) is significantly better than for the previous SABER data set of Mlynczak et al. (2013, ). The agreement decreases if the SCIAMACHY forward model parameters are applied to SABER data. A similar agreement is achieved with the data of Panka et al. (2018, ), which was retrieved from SABER data using a principally different retrieval approach. Plain Language Summary The latest model and laboratory findings on the relaxation of vibrationally excited OH and the wide distribution of recent satellite data have sparked debate on the abundance of atomic oxygen and its impact on the energy balance of the mesopause region. The debate began with the large values originally derived from Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) OH measurements in 2013 and significantly smaller values obtained from Scanning Imaging Absorption Spectrometer for Atmospheric CHartographY (SCIAMACHY) O(S-1) observations in 2014. This confused our understanding of the energy balance of the upper atmosphere and affects the retrieval of several other constituents (temperature, CO2, O-3, etc.), which rely on atomic oxygen a priori data. In this work we present a new atomic oxygen data set based on SCIAMACHY hydroxyl short-wave infrared data. These data and atomic oxygen obtained from SCIAMACHY O(S-1) green line measurements, which is an independent data set in terms of methodology and radiometry, typically agree within 10-20%. This confirms the corresponding models of OH and O(S-1), in particular, the relevance of the reaction between atomic oxygen and ozone in the photochemical model.The agreement between the SCIAMACHY and the most recent SABER atomic oxygen data sets of Mlynczak et al. (2018, ) and Panka et al. (2018, ) is significantly better than for the previous SABER data set. |
