As far as I know, WRF chem uses elevation differences (Ginoux, 2001) to measure potential of dust emission (Erodibility). I needed to use erodibility and expected 2D array, but I found it 3D. I did not know from where this additional dimension is coming from. So, I have checked emission formula of WRF chem and I took it as the multiple of (S) * (sr). <b>F(<i>r</i>) = C <i>L S s</i>(<i>r</i>) u</b><span class=""><b>210m </b></span><b>(u</b><span class=""><b>10m</b></span><b>− u</b><span class=""><b>t</b></span><b>(<i>r,w</i>))</b><i><span style="font-family:arial,sans-serif;font-size:small">. </span></i><i style="font-family:arial,sans-serif;font-size:small">S</i><span style="font-family:arial,sans-serif;font-size:small">: Topographic depression, </span><i style="font-family:arial,sans-serif;font-size:small">s</i><span style="font-family:arial,sans-serif;font-size:small">(</span><i style="font-family:arial,sans-serif;font-size:small">r</i><span style="font-family:arial,sans-serif;font-size:small">): Fraction of particle size class. </span></div>
