<div class="yiv6281408889MsoNormal"><span lang="EN-US" style="font-size: 11pt;">thank you for the links.<u></u><u></u></span></div>
<div class="yiv6281408889MsoNormal"><span lang="EN-US" style="font-size: 11pt;">It works in a sense that I actually get the data plotted. The GRIB2 PDTS 4.6 and 4.10 are decoded.<u></u><u></u></span></div>
<div class="yiv6281408889MsoNormal"><span lang="EN-US" style="font-size: 11pt;"><u></u> <u></u></span></div>
<div class="yiv6281408889MsoNormal"><span lang="EN-US" style="font-size: 11pt;">Do get the plots, I used alt_g2clt with option –raw (my GRIB2 fields are in rotated lon-lat). Without –raw, the ctl-file didn't work.<u></u><u></u></span></div>
<div class="yiv6281408889MsoNormal"><span lang="EN-US" style="font-size: 11pt;">After replacing the start coordinate and the grid spacing in XDEF and YDEF from 0 0.1 to the correct values,<u></u><u></u></span></div>
<div class="yiv6281408889MsoNormal"><span lang="EN-US" style="font-size: 11pt;">I used alt_gmp and it worked.<u></u><u></u></span></div>
<div class="yiv6281408889MsoNormal"><span lang="EN-US" style="font-size: 11pt;">However, the two records in the GRIB2 file which are different in the percentile value are not properly identified.<u></u><u></u></span></div>
<div class="yiv6281408889MsoNormal"><span lang="EN-US" style="font-size: 11pt;">The ctl-File assumes that there is just one record and accordingly, I was able to plot only one record.<u></u><u></u></span></div>

<div class="yiv6281408889MsoNormal"><span lang="EN-US" style="font-size: 11pt;">In general, by splitting my GRIB2 field to individual records, I could work with alt_g2ctl and alt_gmp.<span class="yiv6281408889HOEnZb"><font color="#888888"><u></u><u></u></font></span></span></div><span class="yiv6281408889HOEnZb"><font color="#888888">
