THE ABILITY TO SAMPLE POSSIBLE PLUMES FROM THE SUBSURFACE OCEAN ON EUROPA REPRESENTS A MAJOR STEP IN THE UNDERSTANDING OF POSSIBLE OCEAN WORLDS AND THEIR EXOSPHERES. IF PLUMES EXIST SAMPLING THE EFFLUENT MATERIAL WOULD PROVIDE INSIGHTS INTO THEIR CHEMISTRY AND RELEVANT INFORMATION ABOUT THE PROSPECT THAT LIFE COULD EXIST OR NOW EXISTS WITHIN THE OCEAN. GROUND-BASED OBSERVATIONS CAN OFFER COMPLEMENTARY MEANS TO SENSE EUROPA (REMOTELY) IN PREPARATION FOR IN-SITU OBSERVATIONS. IN 2016 WE INITIATED AN OBSERVATIONAL CAMPAIGN TO CHARACTERIZE THE CHEMICAL COMPOSITION OF EUROPA'S TENUOUS ATMOSPHERE USING HIGH-RESOLUTION INFRARED (IR) SPECTROSCOPY IN THE 2-5.5 MICRON RANGE. WHILE SEVERAL STUDIES HAVE FOCUSED ON THE DETECTION OF WATER OR ITS DISSOCIATION PRODUCTS A MYRIAD OF COMPLEX MOLECULES COULD BE RELEASED BY ERUPTING PLUMES OR ALTERNATIVE EXCITATION EFFECTS LIKE SPUTTERING. OUR IR SURVEY CAN PROVIDE SIMULTANEOUS SENSING OF WATER AND SEVERAL KEY MOLECULAR SPECIES ALLOWING A CHEMICAL CHARACTERIZATION THAT CAN AID THE INVESTIGATION OF PHYSICAL PROCESSES OCCURRING IN EUROPA'S TENUOUS ATMOSPHERE. CURRENT ANALYSES OF THE IR DATA ARE SHOWING SPECTRAL FEATURES THAT GRANT FURTHER INVESTIGATION AND HEREWITH WE PROPOSE TO DISENTANGLE THE POSSIBLE MOLECULAR CONTENT OBSERVED IN THE EUROPAN DATA. THIS ENDEAVOR IS RELEVANT TO THE SOLAR SYSTEM WORKING PROGRAM BECAUSE WE PROPOSE RESEARCH RELATED TO UNDERSTANDING THE ATMOSPHERIC PHYSICAL AND CHEMICAL PROCESSES IN JUPITER'S MOON EUROPA. WE WILL ANALYZE AND INTERPRET EXISTING DATA FROM OUR IR ASTRONOMICAL OBSERVATIONS DELIVER RESULTS IN THE REFEREED LITERATURE AND CREATE A COMPLETE DATABASE WITH CALIBRATED DATA RESULTING FROM OUR GROUND-BASED CAMPAIGN.
