[gradsusr] Maskout

[Jennifer M Adams]

Using the logical expressions in the new version of GrADS, the command would look like this:
‘d maskout(mytemp,mytemp<0)’

But if you don’t have the new version, try this instead:
‘d maskout(mytemp,0-mytemp)’

Subject: [gradsusr] Maskout

Hello

I have this maskout command working for only displaying temperatures above 20(c)

'define mytemp2 = const(const(maskout(mytemp,mytemp-20),1),0.0,-u)'

I cannot figure out how to rewrite that command to display only temperatures below 0(c)
Can anybody help me out?

Thanks
