4 | rn_cio = 5.0e-03 ! ice-ocean drag coefficient (-) |
5 | nn_snwfra = 2 ! calculate the fraction of ice covered by snow (for zdf and albedo) |
6 | ! = 0 fraction = 1 (if snow) or 0 (if no snow) |
7 | ! = 1 fraction = 1-exp(-0.2*rhos*hsnw) [MetO formulation] |
8 | ! = 2 fraction = hsnw / (hsnw+0.02) [CICE formulation] |
9 | rn_snwblow = 0.66 ! mesure of snow blowing into the leads |
10 | ! = 1 => no snow blowing, < 1 => some snow blowing |
11 | nn_flxdist = -1 ! Redistribute heat flux over ice categories |
12 | ! =-1 Do nothing (needs N(cat) fluxes) |
13 | ! = 0 Average N(cat) fluxes then apply the average over the N(cat) ice |
14 | ! = 1 Average N(cat) fluxes then redistribute over the N(cat) ice using T-ice and albedo sensitivity |
15 | ! = 2 Redistribute a single flux over categories |
16 | ln_cndflx = .false. ! Use conduction flux as surface boundary conditions (i.e. for Jules coupling) |
17 | ln_cndemulate = .false. ! emulate conduction flux (if not provided in the inputs) |
18 | nn_qtrice = 1 ! Solar flux transmitted thru the surface scattering layer: |
19 | ! = 0 Grenfell and Maykut 1977 (depends on cloudiness and is 0 when there is snow) |
20 | ! = 1 Lebrun 2019 (equals 0.3 anytime with different melting/dry snw conductivities) |
