TIR temperature retrievals for the Garand atmospheres with SVD of the combined Garand+MEarths temperature matrix (S∕N = 100 and Gaussian SRF as above). Top: LW 660–730 cm⁻¹, poor fits with |ΔT| > 7.5 K; bottom: 2200–2400 cm⁻¹, only fits with ΔT ≥ 8 K. The titles give the atmosphere, number of iterations, and the mean brightness temperature difference. For further details, see Fig. 12.
