<p>Hi ncl-talk, <br>
</p>
<p><br>
</p>
<p>I am trying to create a map showing the number of days with snow depth greater than 200 mm from SNODAS files. I have two scripts attached:</p>
<p><br>
</p>
<p>(1) subsetSNODAS_avgSNWDAYS.ncl<br>
</p>
<p><span style="font-size:12pt">- subsets a smaller region from nation SNODAS domain, </span><span style="font-size:12pt"> </span></p>
<p><span style="font-size:12pt">- calculates the number of days with snow depth greater than user defined threshold</span></p>
<p><span style="font-size:12pt">- calculates 2004-2017 average number of days with snow depth greater than threshold</span></p>
<p><span style="font-size:12pt">- creates .nc file with 2004-2017 average</span></p>
<p><span style="font-size:12pt"><span style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:16px;background-color:rgb(255,255,255)">I have uploaded a few .nc source SNODAS files that serve as input to the subset scrip</span><span style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:16px;background-color:rgb(255,255,255)">t
and the resulting 2004-2017 .nc file to the n</span><span style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:16px;background-color:rgb(255,255,255)">cl-talk ftp site.</span><br>
</span></p>
<p><br>
</p>
<p>(2) plotNESNODAS_snowdays.ncl<br>
</p>
<p>- plots the output .nc file produced in subsetSNODAS_avgSNWDAYS.ncl<br>
</p>
<p>- this is a separate script because the subset script takes a while to run on the full time series for large regions. <br>
</p>
<p><br>
</p>
<p>Thanks, <br>
</p>
