[ncl-talk] Question about wgt_vertical_n

[Joseph Clark]

I don't have a coding error, but a question: how does wgt_vertical_n deal
with values beneath the surface. In other words, for a location with a
surface pressure of 980 hPa, would the extrapolated value on the 1000 hPa
surface be included in the vertical integral? Based on my testing of the
script (by setting enormous values to a variable at the 1000 hPa level),
this appears to be the case. Is there a justification for including
subsurface values in the vertical integral or should the user avoid this by
setting subsurface values to zero?

Thanks!

Joseph
