Wow. I never thought about it like that. If you took into account the "spreading" of data
as the height increased (i.e. increased the spatial density to ensure at least 1 sq.km
coverage and each 100 levels) and decreased the temporal sampling to, say, every five
minutes (so you could measure more things like the temperature, h2o, o3, co2, ch4, no2,
so2, etc, cloud water content, cloud ice content, cloud particle size, shape would be nice
too, aerosol concentration for dust, woc,doc,wbc,dbc, sea salt, and sulphites, etc.. etc..
along with all the surface property measurements) *that* would be a neato dataset.
Only problem is all the wires would get in the way of the weather. :oD
