Wavelength-dependent pressure level where the giant gas planets WASP-43, WASP-103b, WASP-121b, HAT-P-7b, and WASP-18b become optically thick due to cloud particles of different sizes and mixed materials forming inside these atmospheres, that is where p_gas = p(τ_s(λ) = 1), in slant geometry. All results are based on the Parmentier GCM (T_gas, p_gas)-structures, except for WASP-43b where we include both models (Parmentier GCM in green and Carone GCM in grey). When clouds remains optically thin such that τ_s (λ) < 1, the pressure for the bottom of the atmosphere (p ≈ 10^2.2 bar in the Parmentier GCMs) is returned (hence the lines for the sub-stellar points where there is no cloud are outside the plotted range).
