Those will create control files from GRIB data. Then run gribmap on the control files to create an index file. When that's done successfully, you will be able to plot the data in GrADS.<br><br></div>Jeff Duda<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Feb 26, 2015 at 5:05 AM, dolesibeni <span dir="ltr"><<a href="mailto:dolesibeni@gmail.com" target="_blank">dolesibeni@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div><br></div><div>Dear All,</div><div>I am new to grib1 and grib2 data, I downloaded these data sets from ECMWF site and the data is .grib and grb2 formart.
