Heat fluxes tested for Uranus and Neptune as a function of the temperature range in the thermosphere and the thickness of this layer.

Name ΔT (K) Δɀ (km) Qc,bottom (W m−2)
UC1 170–500 1100 6.5 × 10−5
UC2 150–500 260 2.62 × 10−4
UC3 150–500 50 1.36 × 10−3
NC1 150–750 1450 1.07 × 10−4
NC2 150–750 10 1.56 × 10−2

Notes. For Uranus, two values of conductivity were tested (see text). Qctop corresponds to the value of conduction flux at the top of the thermosphere and is equal to 0.
