micru background map and effective cloud fraction algorithms designed for uv vis Satellite Instruments with large viewing angles
Atmospheric Measurement Techniques Discussions, 2020Co-Authors: Holger Sihler, Steffen Beirle, Steffen Dorner, Marloes Gutensteinpenning De Vries, Christoph Hormann, Christian Borger, Simon Warnach, Thomas WagnerAbstract:Abstract. Clouds impact the radiative transfer of the Earth's atmosphere and strongly influence Satellite measurements in the UV visible and IR spectral ranges. For Satellite measurements of trace gases absorbing in the UV/vis spectral range, particularly clouds ultimately determine the vertical sensitivity profile, mainly by reducing the sensitivity for trace gas columns below the cloud. The Mainz Iterative Cloud Retrieval Utilities (MICRU) algorithm is specifically designed to reduce the error budget of trace gas retrievals, such as those for nitrogen dioxide (NO2), which strongly depends on the accuracy of small cloud fractions (CF) in particular. The accuracy of MICRU is governed by an empirical parametrisation of the viewing geometry dependent background surface reflectivity taking instrumental and physical effects into account. Instrumental effects are mainly degradation and polarisation effects, physical effects are due to the anisotropy of the surface reflectivity, e.g. shadowing of plants and sun glitter. MICRU is applied to main science channel (MSC) and polarisation measuring device (PMD) data collected between April 2007 and June 2013 by the GOME-2A instrument onboard the MetOp-A Satellite. CF are retrieved at different spectral bands between 374 and 758 nm. The MICRU results for MSC and PMD at different wavelengths are inter-compared to study CF precision and accuracy, which depend on wavelength and spatial correlation. Furthermore, MICRU results are compared to FRESCO (Fast Retrieval Scheme for Clouds from the Oxygen A band) and OCRA (Optical Cloud Recognition Algorithm) operational cloud products. We show that MICRU retrieves small CF with an accuracy of 0.04 or better for the entire 1920 km wide swath with a potential bias between −0.01 and −0.03. CF retrieved at shorter wavelengths are less affected by adverse surface heterogeneities. The comparison to the operational CF algorithms shows that MICRU significantly reduces the dependence on viewing angle, time, and sun glitter. Systematic effects along coasts are particularly small for MICRU due to its dedicated treatment of land and ocean surfaces. The MICRU algorithm is designed for spectroscopic Instruments ranging from the GOME to TROPOMI/Sentinel-5P, but is also applicable to UV/vis imagers like, for example, AVHRR, MODIS, VIIRS, and Sentinel-2.

Monitoring Nitrogen Oxides in the troposphere with Satellite Instruments
2020Co-Authors: Steffen Beirle, Ulrich Platt, Thomas WagnerAbstract:We present the results of several studies on the identification and quantification of the different sources of NOx (traffic, industry, biomass burning, lightning) from GOME Satellite data. Furthermore, we demonstrate the potential of Satellite data to estimate the mean lifetime of tropospheric NOx.

monitoring of atmospheric trace gases clouds aerosols and surface properties from uv vis nir Satellite Instruments
Journal of Optics, 2008Co-Authors: Thomas Wagner, Steffen Beirle, T. Deutschmann, E. Eigemeier, Christian Frankenberg, M. Grzegorski, T. Marbach, Ulrich Platt, Penning M De VriesAbstract:A new generation of UV/vis/near-IR Satellite Instruments like GOME (since 1995), SCIAMACHY (since 2002), OMI (since 2004), and GOME-2 (since 2006) have allowed one to measure backscattered solar radiance from the Earth with moderate spectral resolution over a large wavelength range (240–790 nm). The SCIAMACHY instrument also includes additional spectral channels in the near-IR. From the measured spectra several important stratospheric and tropospheric trace gases (e.g. O_3, NO_2, OClO, HCHO, SO_2, BrO, H_2O) as well as clouds, aerosols and surface properties can be determined from space. Because of its extended spectral range, the SCIAMACHY instrument also allows the retrieval of greenhouse gases (CO_2, CH_4) and CO in the near-IR. Almost all of the tropospheric trace gases have been observed by these Instruments for the first time. From Satellite data it is possible to investigate their temporal and spatial variation. Also, different sources can be characterized and quantified. The derived global distributions can serve as input and for the validation of atmospheric models. Here we give an overview of the current status of these new Instruments and data products and their recent applications in the investigation of various atmospheric and oceanic phenomena.
