1 J. AJELLO I. STEWART M. STEVENS A.AGUILAR K. LARSEN
COMPARISON OF TITAN EUV AIRGLOW SPECTRA WITH FUSE EARTH AND LABORATORY SPECTRA J. AJELLO I. STEWART M. STEVENS A.AGUILAR K. LARSEN

2 UVIS GOALS OVERPLOT SPECTRA (UVIS,FUSE, LAB) LAB GOALS:
IDENTIFICATION OF EUV UVIS FEATURES FROM HIGH RESOLUTION LAB SPECTRA (0.05 TO 0.6 A FWHM) APPROXIMATE PHOTOELECTRON EXCITATION-MEAN ENERGY BY COMPARING eV LAB SPECTRA NITROGEN FOREGROUND ABUNDANCES MEASURE Qem AND hpre.FOR MODELS LONG RANGE GOALS-COMPARE SPACE WEATHER (THERMAL STRUCTURE, COMPOSITION AND SOLAR ENERGY INPUT) OF EARTH FROM FUSE AND OF TITAN FROM UVIS SPECTRA INCLUDE SOLAR PHOTIONIZATION AND e + N

3 LABORATORY COMPARISON TO TITAN EUV SPECTRUM

4 COMPARISON OF TITAN, FUSE AND LABORATORY (OPTICALLY THICK h=1015 cm-2) EUV SPECTRA

5 COMPARE SPECTRA AT UVIS 4A FWHM NORMALIZED TO N2 c’(3,2;4,3) AT 943 A

6 IDENITIFICATION OF OVER 100 FEATURES FROM N AND N2 OVER RANGE OF 850-1150 A

13 CONCLUSIONS EARTH AND TITAN PRESENT SIMILAR EUV SPECTRA OVER 100 N AND N2 FEATURES CONTRIBUTE TO TITAN EUV CHANNEL UVIS SPECTRA EXCEPT FOR N2(c’[0,1]) BAND UVIS SPECTRUM IS WELL-MATCHED BY eV OPTICALLY THICK LAB SPECTRA OF e + N2
