<p>Hi all,</p>

<p>NOAA AHPS changed their netcdf for format for the precipitation data as stated here:

<p>Now this ctl does not work nor does ncdump read the new file from <a href="http://water.weather.gov/precip/downloads/" class="OWAAutoLink" id="LPlnk476671" previewremoved="true">
http://water.weather.gov/precip/downloads/</a></p>
<p><br>
</p>
<p>Has anyone had any success opening the new updated precip data in GrADS from AHPS? If so, do you have a ctl file you could share?</p>
<p><br>

<p>Thanks,</p>
