Addition of Sturm (1997) & Calonne (2019) Thermal Conductivity Methods #57

Open MarcusGastaldello opened 10 months ago

MarcusGastaldello commented 10 months ago

Addition of two new empirical methods to calculate layer thermal conductivity:

  1. Sturm et. al., 1997 (https://doi.org/10.3189/S0022143000002781)
  2. Calonne et al., 2019 (https://doi.org/10.1029/2019GL085228)

(Note: existing 'empirical' method renamed to 'Huintjes15' to improve clarity and avoid confusion.)

These new methods were found to be much more representative than the bulk approach against observed cold firn conditions at Colle Gnifetti, Monte Rosa Massif, Switzerland. At low densities they often yield much lower thermal conductivities greatly influencing the sub-surface thermal regime.
