Find the LCL / 'define' problem

Dear GrADS users,

I try to calculate LCL in my gridded data set (terrain following model
layers).

My algorithm steps upward from the surface iteratively always one
level, calculates the thetaE at this level and compares
with the mixing ratio in order to check, wether LCL is reached or not.

This works fine for one single gridpoint, but how can I find
the LCL's over the whole domain? Since, it is reached at
different vertical levels, I cannot just do the calculation
with the whole array.....

Is there a way to go through every gridpoint and define
a single variable 'lcl' dependent on lat/lon?

Thanks in advance for your help and proposals,

Marco
