<h1>Forecast Model Vertical Sounding<a class="headerlink" href="#forecast-model-vertical-sounding" title="Permalink to this headline"></a></h1>
<p><a class="reference external" href="http://nbviewer.ipython.org/github/Unidata/python-awips/blob/master/examples/notebooks/Forecast_Model_Vertical_Sounding.ipynb">Notebook</a>
The ModelSounding class allows us to create a vertical sounding through
any available AWIPS model with isobaric levels.</p>
<ul class="simple">
<li><p>A Shapely Point geometry is used to select longitude and latitude:
from shapely.geometry import Point point = Point(-104.67,39.87)</p></li>
<li><p>Parameters <code class="docutils literal notranslate"><span class="pre">['T','DpT','uW','vW']</span></code> are requested for all isobaric
levels available for the selected model.</p></li>
<li><p>There is a single-record query performed for <code class="docutils literal notranslate"><span class="pre">level</span> <span class="pre">=</span> <span class="pre">&quot;0.0FHAG&quot;</span></code> to
determine the surface pressure level.</p></li>
<li><p>Pay attention to units when switching models. This notebook was
written for the NAM 40km AWIPS model where temperature and dewpoint
are returned as Kelvin and wind components as m/s.</p></li>
