Dear Ted

Thanks for this explanation:

> Albedo is the ratio of outgoing irradiance to incoming irradiance
> and is unitless.

Lambertian equivalent in the name. Thus:

> toa_lambertian_equivalent_albedo
> toa_lambertian_equivalent_albdeo_multiplied_by_cosine_solar_zenith_angle

OK, with small L in lambertian as you had before (because stdnames are all
in lower case). Thanks!

Cheers
