log interpolation of windspeed

[bnb32]

Implement log interpolation of windspeed in data handler extraction.

Good references at the links below. Had a really hard time getting the reading log fit to solve correctly. Note that if we use a power law extrapolation from a single surface wind (e.g., for some GCMs with limited data), we should extrapolate absolute windspeed and maintain direction.

Yeah I've been looking at this - https://en.wikipedia.org/wiki/Log_wind_profile. Seems the first link above has a sign mismatch with the wiki?

With the -d versus +h for the displacement height? Could be a mistake, although when using the algorithm from reading h was not constrained to be positive.

Yeah, and in some of my testing I got d to be negative when using -d anyway.
