I'm not aware of one. You'd have to compute the dry and moist adiabatic lapse rates yourself. However, since you are running the WRF, you could use ARWpost and manipulate the module that computes CAPE to give you lifted index. Most of the hard work in computing it is already done. You would just need to add code to spitting out the array into a binary file.<br>

Dear users,<br>
<br>
Does anybody have a script to calculate the Lifted Index?<br>
I am running WRF model and this index is not available in version 3.<br>
The problem is the parcel temperature.<br>
<br>
Thanks,<br>
