<div dir="ltr">Jennifer,<div><br></div><div> After a month long warning I changed today the defult grads version at our office from 2.0.1.oga.1 to 2.0.2.oga.1 and the transition didn't go well. Our pressure level files have the following level coordinate variable:</div>
<div><br></div><div><p style="margin:0px;font-size:14px;font-family:Monaco;color:rgb(2,32,179)"><span class="" style="white-space:pre"> </span>double lev(lev) ;</p>
<p style="margin:0px;font-size:14px;font-family:Monaco;color:rgb(2,32,179)"><span class="" style="white-space:pre"> </span>lev:long_name = "vertical level" ;</p>
<p style="margin:0px;font-size:14px;font-family:Monaco;color:rgb(2,32,179)"><span class="" style="white-space:pre"> </span>lev:units = "hPa" ;</p><div><br></div><div>However, when I open this file in grads 2.0.2 I get this message:</div>

This problen makes 2.0.2 unusable for us.</div>
<div><br></div><div>I verified that this problem has been fixed in 2.1.a2. While I could make 2.1.a2 the default, it would be a good idea to have the latest stable release as a fallback. Do you happen to have a (source code) patch for this unit conversion problem in 2.0.2?</div>
