THE GROWING CENSUS OF EXOPLANETS INCLUDES A BURGEONING AMOUNT OF SPECTRAL DATA THAT CAN BE USEFUL FOR THE CHARACTERIZATION OF EXOPLANETARY ATMOSPHERES. CURRENTLY ATMOSPHERES THAT RESEMBLE OUR SOLAR SYSTEM S TERRESTRIAL PLANETS ARE WELL CHARACTERIZED BY RADIATIVE TRANSFER MODELS THAT ARE FOUNDED ON LABORATORY-BASED MOLECULAR SPECTROSCOPY MEASUREMENTS. HOWEVER FOR MORE EXTREME-TEMPERATURE ATMOSPHERES THERE IS LIMITED LABORATORY DATA AVAILABLE TO CREATE AND VALIDATE MODELS. IN LIEU OF LABORATORY DATA THEORETICAL METHODS (E.G. EXOMOL) HAVE PRODUCED DATA SUITABLE FOR MANY ASPECTS OF EXOPLANET ANALYSES. WE CONTEND THAT THESE THEORETICAL METHODS ARE NOT YET PROFICIENT FOR EXTRACTION OF SCIENTIFIC INFORMATION FOR HIGH-TEMPERATURE NONLINEAR POLYATOMIC MOLECULES (E.G. METHANE AND WATER). THE PROPOSED EFFORT UTILIZES A NEW RESOURCE FOR HIGH TEMPERATURE LABORATORY SPECTROSCOPY A BROADBAND HIGH-RESOLUTION DUAL FREQUENCY COMB SPECTROMETER COUPLED WITH A HIGH-TEMPERATURE OPTICAL CELL FACILITY TO MAKE FIRST-OFKIND ACCURATE LABORATORY MEASUREMENTS OF THE ABSORPTION SPECTRA OF WATER AND METHANE AT TEMPERATURES UP TO 1300 K. THE MEASURED DATA IS THEN ANALYZED USING A PARAMETERIZED PHYSICAL MODEL (LABFIT) THAT IS ALREADY USED FOR HIGH FIDELITY SPECTRAL ANALYSES FOR NASA MISSIONS. THE RESULTING INFORMATION IS USEFUL FOR BOTH (1) DIRECT SPECTRAL AND RADIATIVE TRANSFER MODELING OF EXOPLANET ATMOSPHERES; AND (2) EVALUATION OF THE THEORETICAL EXOMOL DATA. TO THAT END THE PROPOSED EFFORT INCLUDES GENERATING NEW SPECTROSCOPIC DATABASES FOR WATER VAPOR AND METHANE IN SPECTRAL REGIONS IMPORTANT TO CURRENT HUBBLE TELESCOPE AND FUTURE JAMES WEBB SPACE TELESCOPE EXOPLANET OBSERVATIONS. WE WILL INCORPORATE THE DATABASES INTO THE EXCALIBUR SCIENCE DATA PIPELINE AND ASSESS THE IMPACT OF THE DATABASE IMPROVEMENTS ON RETRIEVALS FROM 57 CURRENT AND PLANNED OBSERVATIONS.
