SCRIBE DATA VALIDATION AND ANALYSIS

WE PROPOSE TO INVESTIGATE THE POTENTIAL OF THE UNIQUE SCRIBE HIGH RESOLUTION ATMOSPHERIC EMISSION SPECTRA AND ITS DIURNAL VARIATION IN SEVERAL APPLICATIONS. WE WILL VALIDATE THE SPECTRA BY COMPARISON WITH CALCULATED REFERENCE SYNTHETIC SPECTRA AND WITH OTHER SYNTHETIC SPECTRA. WE WILL CHECK TO SEE WHETHER DISCREPANCIES CAN BE REDUCED OR ELIMINATED BY VARYING THE PROFILES OF TRACE GASES, AND WHETHER ANY REMAINING DISCREPANCIES SUGGEST CHANGES IN THE AFGL SPECTRAL LINE PARAMETERS COMPILATION. WE WILL USE VERY OPAQUE AND VERY TRANSPARENT PARTS OF THE SPECTRA TO OBTAIN INDEPENDENT CALIBRATION POINTS. WE WILL SEARCH FOR UNEXPLAINED LINES AND ATTEMPT TO IDENTIFY THE RESPONSIBLE CONSTITUENT FROM OUR ESTIMATES OF ITS VARIATION WITH HEIGHT, AND FROM LINE SPACING AND INTENSITY DISTRIBUTION. IN PARTICULAR, WE WILL SEARCH FOR LINES OF PHOTOCHEMICALLY ACTIVE MOLECULES WITH EXPECTED DIURNAL VARIATION, TO HELP UNDERSTAND OZONE-RELATED PHOTOCHEMISTRY AND DIURNAL VARIATIONS OF STRATOSPHERIC TRANSPARENCY. WE WILL DEVELOP AND TEST ALGORITHMS FOR RETRIEVING COMPOSITION AND TEMPERATURE PROFILES.
