AB: HIRDLS is a 21-channel limb-scanning infrared radiometer launched on the Aura satellite on 15 July, 2004. It's purpose is to measure radiances from which the vertical distributions of temperature, ozone, water vapor, and 8 other gases of chemical, radiative, or dynamical importance can be retrieved, as well as aerosol distributions. HIRDLS has been designed to obtain data with higher horizontal and vertical resolution than previously available. HIRDLS activation took place over 25 days, culminating in the detector cool-down. Unfortunately, HIRDLS experienced difficulties in seeing the atmosphere. Depending on experiment status, this talk will present and describe atmospheric data, or discuss the investigation into the anomaly. In that case we will describe the symptoms, which included observed radiances that appeared too large over most of the field of view, and increased damping of the scanner motion. The latter condition has required initial investigations with the scanner not moving. Several lines of inquiry are in motion, which we feel will resolve the likely causes of the observations, and point to remedial actions. Available data will be presented, and an outlook given for the future.
