Title: Dispersed Imaging for Atmospheric Characterization, in preparation for LSST

Abstract: We propose to obtain dispersed imaging with the CTIO 0.9m in order to monitor in detail the evolution of atmospheric transparency during the night. The 0.9m is a very close approximation to the atmospheric calibration telescope that will be installed at the LSST site, and we are using the 0.9m to develop the methodology, instrumentation, flatfielding techniques, and reduction software we will need during LSST operations. We have had two successful test runs to date, and are now proposing to undertake a sequence of observations over the course of the semester. The Ronchi grating we use in the beam suppresses second order diffraction, and so we can obtain R$sim0 spectral resolution of atmospheric transmission over the entire range of 350 nm to 1 micron.
