Intercomparison of daytime stratospheric NO2 satellite retrievals and model simulations
This paper evaluates the agreement between stratospheric NO2 retrievals from infrared limb sounders (Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) and High Resolution Dynamics Limb Sounder (HIRDLS)) and solar UV/VIS backscatter sensors (Ozone Monitoring Instrument (OMI), Scanning Imaging Absorption Spectrometer for Atmospheric Cartography (SCIAMACHY) limb and nadir) over the...
متن کاملReplies to Interactive Comments AMT2013-336 “Daytime stratospheric NO2 retrievals” Authors’ response to Anonymous Referee #1
(1) An important point is the large bias (30-50%) between OMI (KNMI DOMINO v2.0) and SCIAMACHY nadir (KNMI-BIRA TM4NO2A v2.3) retrievals, especially if both data sets are photochemically converted. It is puzzling me because Dirksen et al. (2011) and Hendrick et al. (2012) found a good agreement between OMI, SCIAMACHY nadir and groundbased observations, suggesting the absence of such a large bia...
متن کاملStratospheric and tropospheric NO2 variability on the diurnal and annual scale: a combined retrieval from ENVISAT/SCIAMACHY and solar FTIR at the Permanent Ground-Truthing Facility Zugspitze/Garmisch
Columnar NO2 retrievals from solar FTIR measurements at the Zugspitze (47.42 N, 10.98 E, 2964 m a.s.l.), Germany were investigated synergistically with columnar NO2 retrieved from SCIAMACHY data by the University of Bremen scientific algorithm UB1.5 for the time span July 2002–October 2004. A new concept to match FTIR data to the time of satellite overpass makes use of the NO2 daytime increasin...
متن کاملStratospheric NO and NO2 abundances from ATMOS SolarOccultation Measurements
Using results from a time-dependent photochemical model to calculate the diurnal variation of NO and NO2, we have corrected Atmospheric Trace MOlecule Spectroscopy (ATMOS) solar-occultation retrievals of the NO and NO 2 abundances at90 ø solar zenith angle. Neglecting to adjust for the rapid variation of these gases across the terminator results in potential errors in retrieved profiles of-20% ...
متن کاملValidation of version 5.20 ILAS HNO3, CH4, N2O, O3, and NO2 using ground-based measurements at Arrival Heights and Kiruna
Ground-based measurements of O3 and NO2 columns at Kiruna (68°N) and Arrival Heights (78°S) were used to validate stratospheric profile measurements of the same species by the satellite-based Improved Limb Atmospheric Spectrometer (ILAS) flown between November 1996 and June 1997. In addition, measurements of HNO3, CH4, and N2O made at Arrival Heights are compared with measurements of these spec...
