Exoplanetary transmission spectroscopy in the near-infrared using Hubble Space Telescope (HST) NICMOS is currently ambiguous because different observational groups claim results from same data, depending on their analysis methodologies. Spatial scanning with HST/WFC3 provides an opportunity to resolve this ambiguity.

Abstract Clouds are prevalent in many of the exoplanet atmospheres that have been observed to date. For transiting exoplanets, we know if clouds present because they mute spectral features and cause wavelength-dependent scattering.
