“…Measurements made by the Global Ozone Monitoring Experiment GOME [Burrows et al, 1999] and a groundbased zenith-sky spectrometer [Richter, 1997] As an example of model application Ring DODs were calculated for both simulated and measured spectra observed on the 13th June 1996. Solar zenith angles and cloud conditions described by Richter [1997] were used for simulations, including modeling of the reference spectrum Ire oe.…”

Abstract. Filling-in of spectral features observed in scattered sunlight and known as the "Ring Effect" has a significant impact on the retrieval of atmospheric trace constituents from both ground-based and satellite observations. As clouds also have strong impacts on radiative transfer in the UV/visible spectral range, possible changes of the Ring Effect due to clouds have to be considered. Such investigations require radiative transfer modeling explicitly accounting for both cloud and Ring features. UV/visible ground and satellite based measurements, taken under cloudy conditions, were used to validate Ring and cloud modeling using the radiative transfer model SCIATRAN. As an example results of model applications are presented for both groundbased and satellite geometry. Two case studies are used to explain the sources of the observed Filling-in.

“…Observational constraints of ozone precursors traditionally rely on in situ measurements at the local to regional scale. More recently constraints at the regional to global scale are being provided by satellite instruments such as the Global Ozone Monitoring Experiment (GOME) [European Space Agency, 1995;Burrows et al, 1999]. Validation of GOME observations with coincident in situ measurements at the regional scale is a prerequisite for using GOME to link regional and global-scale processes.…”

[1] We compare tropospheric measurements of nitrogen dioxide (NO 2 ) and formaldehyde (HCHO) from the Global Ozone Monitoring Experiment (GOME) satellite instrument with in situ measurements over eastern Texas and the southeast United States. On average, the GOME and in situ measurements of tropospheric NO 2 and HCHO columns are consistent despite pronounced sampling differences. The geometric mean in situ to GOME ratios over the campaign are 1.08 for NO 2 and 0.84 for HCHO, with corresponding geometric standard deviations of 1.27 and 1.38. The correlation of the observed column spatial variability between the two NO 2 measurement sets is encouraging before (r 2 = 0.54, n = 18) and after (r 2 = 0.67, n = 18) correcting for a sampling bias. Mean relative vertical profiles of HCHO and NO 2 calculated with a global three-dimensional model (GEOS-CHEM) and used in the GOME retrieval are highly consistent with in situ measurements; differences would affect the retrieved NO 2 and HCHO columns by a few percent. GOME HCHO columns over eastern Texas include contributions from anthropogenic volatile organic compound (VOC) emissions but are dominated by biogenic VOC emissions at the regional scale in August-September when HCHO columns are within 20% of those over the southeastern United States. In situ measurements show that during summer the lowest 1500 m (the lower mixed layer) contains 75% of the tropospheric NO 2 column over Houston and Nashville, and 60% of the HCHO column over Houston. Future validation of space-based measurements of tropospheric NO 2 and HCHO columns over polluted regions should include coincident in situ measurements that span the entire satellite footprint, especially in the heterogeneous mixed layer. .

“…However, in the 325-335nm window in which ozone is retrieved, the ozone absorption is strong and the ozone AMF shows a significant wavelength dependence at, high solar zenith angles (SZA). For SZA< 70 ø the •mcertainty in the AMF is conservatively estimated to be 5% [Burrows et al, 1999] Since Dobson stations do not provide pole-to-pole coverage, it was decided to use the Dobson-satellite int, ercomparisons to first remove offsets and trends only in the N7T and EPT data (see Table 1 for abbreviations) and then to make use of global intercomparisons in equivalent latitude space between M3T and corrected N7T to correct the M3T data, GOME and corrected EPT to correct, the GOME data, and ADT and corrected EPT to to correct the ADT data. …”
