On p. 6 of this article:

Bliss, A.K., Cuffey, K.M., Kavanaugh, J.L., 2011. Sublimation and surface energy budget of Taylor Glacier, Antarctica. Journal of Glaciology 57, 684–696.

There is an expression for sublimation rate as a function of latent heat flux $L$ and (specific) latent heat of sublimation (of water ice) $\lambda$.

enter image description here

But then $L$ itself is given as a function of the latent heat of sublimation ($\lambda$):

So... doesn't $\lambda$ cancel out!? This would imply that the latent heat of sublimation doesn't matter at all here, which I guess is possible since it's a kinetically controlled process.
