[wxqc] L in APRS packet...

[Gerry Creager]

I'm actually interested in the inverse problem: With a satellite-based 
estimate of cloud cover (combined infrared, water vapor radiometry, and 
possibly some surrogate direct/diffuse solar by means of a separate 
temperature channel.

Several of us think we can then estimate evaptranspiration using a 
modified method...
