Cloudy transmission spectra. We illustrate the moist, biotic scenario 2 (red), the abiotic steam scenarios 3 (purple) and 4 (grey), and the desiccated scenario 4 for the JWST/NIRSpec wavelength range 3 – 5 µm (top) and the JWST/MIRI wavelength range between 5 – 10 µm (bottom) with simulated noise (black error bars). We chose the G235M (2-3 µm) and G395M grism setting (3-5 µm), each with 10 pixels per bin (top), and the MIRI LRS setting with 5 pixels per bin (bottom).
