<p>Hi </p>
<p><br>
</p>
<p></p>
<div>This example pulls the global attributes off a file and prints out their values:<br>
<br>
f = addfile("$NCARG_ROOT/lib/<wbr>ncarg/data/cdf/<a href="http://uv300.nc" target="_blank">uv300.nc</a>","r")<br>
<br>
file_atts = getvaratts(f)<br>
<br>
print(file_atts)<br>
<br>
if(.not.any(ismissing(file_<wbr>atts))) then<br>
do i=0,dimsizes(file_atts)-1<br>
print("Attribute " + file_atts(i) + " = " + f@$file_atts(i)$)<br>
end do<br>
end if</div>
<br>
<p></p>
<p>How can one pull out a specific attribute from the file f and use it ?</p>
<p><br>
</p>
<p><br>
