ARTS Microwave Single Scattering Properties Database (Oriented Particles)

<p>The database contains microwave and submillimeter wave single scattering data of azimuthally randomly oriented frozen hydrometeors. Main applications lie in polarized active/passive microwave and submillimeter wave remote sensing. This database is an independent add-on to the&nbsp;<a href="https://doi.org/10.5281/zenodo.1175572">ARTS Microwave Single Scattering Properties Database</a>.</p> <p>A description of the simulation methods and database is available in the following article. Please cite it if you use the database for a publication. Brath, M., Ekelund, R., Eriksson, P., Lemke, O., and Buehler, S. A.: Microwave and submillimeter wave scattering of oriented ice particles, Atmos. Meas. Tech. Discuss., <a href="https://doi.org/10.5194/amt-2019-382">https://doi.org/10.5194/amt-2019-382</a>, in review, 2019.</p> <p>The dataset contains one aggregate habit and one pristine ice crystal habit. Furthermore, 35 frequencies from 1 to 886 GHz, and 3 temperatures, 190, 230 and&nbsp; 270 K, are included. The data were calculated using the discrete dipole approximation method (DDA) in combination with a self developed orientation averaging approach. Interfaces for easy user access is available under a separate upload, due to different licensing, under the title <a href="https://doi.org/10.5281/zenodo.1175588">ARTS Microwave Single Scattering Properties Database Interfaces</a>, in which only the Python3 interface can be used for browsing and importing of the single scattering data of azimuthally randomly oriented.&nbsp;The archive InputAzimuthallyRandom.tar.gz contains the shape files,&nbsp;which have be used as input for the DDA simulations.</p> <p><strong>Unpacking</strong></p> <p>The data files for the oriented particles follow the same directory structure as the <a href="https://zenodo.org/record/1175573">ARTS Microwave Single Scattering Properties Database</a>. Each tar file contains an SSD directory and the subdirectories for a specific particle orientation. Furthermore, it contains as a quick overview a report of the scattering properties for total random orientation.</p> <p>If the totally randomly oriented particle database is already present, these files should be unpacked in the same location that contains the SSD folder.</p> <p>In Unix, all files can be unpacked with:</p> <pre><code class="language-bash">for ssdfile in SSD-AziRnd-ice*.tar; do tar -xvf $ssdfile done </code></pre>
