. The Spatial Heterodyne Observations of Water instrument (SHOW) is alimb-sounding satellite prototype that utilizes the Spatial HeterodyneSpectroscopy (SHS) technique, operating in a limb-viewing configuration, toobserve limb-scattered sunlight in a vibrational band of water vapour withina spectral window from 1363 to 1366 nm. The goal is to retrieve highvertical and horizontal resolution measurements of water vapour in the uppertroposphere and lower stratosphere. The prototype instrument has beenconfigured for observations from NASA's ER-2 high-altitude airborne remotescience airplane. Flying at a maximum altitude of ∼21.34  km with amaximum speed of ∼760  km h −1 , theER-2 provides a stable platform to simulate observations from a low-earthorbit satellite. Demonstration flights were performed from the ER-2 during anobservation campaign from 15 to 22 July 2017. In this paper, we present thelaboratory characterization work and the level 0 to level 1 processing offlight data that were obtained during an engineering flight performed on18 July 2017. Water vapour profile retrievals are presented and compared toin situ radiosonde measurements made of the same approximate column of air.These measurements are used to validate the SHOW measurement concept andexamine the sensitivity of the technique.
