AB: HIRDLS is an infrared limb-scanning radiometer, which was launched on the Aura spacecraft 15 July 2004. HIRDLS is designed to sound the upper troposphere, stratosphere, and mesosphere to determine temperature; the concentrations of O3, H2O, CH4, N2O, NO2, HNO3, N2O5, ClONO2, CFC11, CFC12, and aerosols; and the locations of polar stratospheric clouds and cloud tops. The HIRDLS instrument was designed to obtain global distributions of constituents with horizontal and vertical resolution superior to that previously measured. The vertical resolution is approximately 1.2 km. The horizontal resolution is tunable depending on science and validation needs. Typical scan modes have a 5 x 5 degrees global coverage over a 12-hour period. This presentation will give an overview of the validation status of each HIRDLS data product with correlative data from ground based, sondes, aircraft, and other satellite instruments. Specific comparisons between HIRDLS and the Houston October/November 2004 Aura Validation Experiment (AVE) will be shown. In addition, cross comparisons between HIRDLS and the other Aura instruments (i.e., MLS, TES, and OMI), along with available occultation and other limb viewing instruments will be shown.
