The UVS instrument carried aboard the LADEE mission performed spectral characterization of the lunar atmosphere, including gases and dust at several wavelengths.  This characterization entailed measuring the relative concentrations of certain species, including Na and K, and noting the spatial and temporal distributions of those species.
