THE PROPOSED WORK IS DIRECTLY RELEVANT TO THE OVERALL GOAL OF HABITABLE WORLDS TO USE KNOWLEDGE OF THE HISTORY OF THE EARTH AND THE LIFE UPON IT AS A GUIDE FOR DETERMINING THE PROCESSES AND CONDITIONS THAT CREATE AND MAINTAIN HABITABLE ENVIRONMENTS. IN PARTICULAR ORGANIC HAZES MAY HAVE PLAYED A KEY ROLE IN THE HABITABILITY OF EARLY EARTH BY INFLUENCING THE TEMPERATURE UV FLUX AND NUTRIENTS AVAILABLE TO EARLY LIFE. A MORE COMPLETE PICTURE OF HAZE IMPACTS ON HABITABILITY WILL BE EXPLORED BY SIMULTANEOUSLY USING MULTIPLE ANALYTICAL TECHNIQUES TO CONSTRAIN THE SSA AND CHEMICAL COMPOSITION OF GASES AND PARTICLES.
