Cool gaseous exoplanets (1.75 R_⊕ < Rp < 3 RJ, 200 K 5σ significance. We find that an injected mass-metallicity trend is well-recovered, demonstrating Twinkle's ability to elucidate this fundamental relationship into cool regime. We also find Twinkle will be able to detect cloud layers at 3σ or greater in all cool gaseous planets for clouds at ≤ 10 Pa pressure level, but will be insensitive to clouds deeper than 104 Pa in all cases. With these results we demonstrate the capability of the Twinkle mission to greatly expand the current knowledge of cool gaseous planets, enabling key insights and constraints to be obtained for this poorly-charted region of exoplanet parameter space.
