The syntax is: <p> <code>coll2gr(<i>cnum <,num></i>)</code> <p> <ul> <code><i>cnum</i> </code> collection number<br> <code><i>num</i> </code> number of vertical levels in the output grid (default is 10)<br> </ul> <p> If <code><i>num</i></code> is given as <code>"-u"</code>, then the vertical levels will be a union of all the levels in the collection of station data. <p> <h3>Usage Notes</h3> <p> <ol> <li>Before using <code>coll2gr</code>, you must create the collection of stations using the GrADS command <a href="gradcomdcollect.html"><code>collect</code></a>. <p> <li><code>coll2gr</code> does not yet support time slices; currently, it will only work when the collection of stations is a collection of vertical profiles. <p> <li><code>coll2gr</code> produces an output grid that varies in X and Z; the dimension environment used when <code>coll2gr</code> is invoked must also be X and Z varying. The X axis of the output grid will contain the equally spaced station profiles and will span the range of the current X dimension environment. The Z axis of the output grid will span the range of the current Z dimension environment and will have either the specified number of levels or a union of the levels. Data points outside of the range of levels will be used for interpolating to within the range if appropriate. <p> <li>The <code>"-u"</code> option will only work for data in pressure vertical coordinates. If your vertical coordinate is height, <code><i>num</i></code> should be the actual number of vertical levels in the collection of profiles. <p> <li>See the section of the User's Guide on <a href="usingstationdata.html#xsection">Arbitrary Cross Sections</a> for more information. </ol> <p> <h3>Examples </h3> </body> </html>
