Aura, the last of the large Earth Observing System observatories, was launched on July 15, 2004. Aura is designed to make comprehensive stratospheric and tropospheric composition measurements from its four instruments, the High Resolution Dynamics Limb Sounder (HIRDLS), the Microwave Limb Sounder (MLS), the Ozone Monitoring Instrument (OMI), and the(More)
[1] Nearly coincident observations of HNO3, HCl, N2O, and H2O in the vicinity of the northern polar vortex during the NASA Polar Aura Validation Experiment (PAVE) in January and February 2005 have shown reasonably good agreement between aircraft-borne infrared spectrometer results and results from High Resolution Dynamics Limb Sounder (HIRDLS), Microwave(More)
Results from an instrument-level spectral characterization of the 21-channel High Resolution Dynamics Limb Sounder (HIRDLS) flight instrument will be presented. These data were obtained during the prelaunch calibration of HIRDLS at the University of Oxford (fall 2002). A monochromator, equipped with a controllable diffraction grating, was used to produce(More)
