AS THE LARGEST ICE SHEET IN THE NORTHERN HEMISPHERE GREENLAND ICE SHEET (GRIS) SNOW AND ICE MELT IS OF INTEREST TO THE SCIENTIFIC COMMUNITY. EXTENSIVE MELT ASSOCIATED WITH THE GRIS COULD LEAD TO DRASTIC SEA LEVEL RISE AND CHANGING OCEAN WATER PROPERTIES AROUND GREENLAND. THERE ARE MANY NATURAL AND ANTHROPOGENIC TRIGGERS THAT COULD CAUSE INCREASED SNOWMELT OF THE GRIS. THESE INCLUDE THE PRESENCE OF LIGHT-ABSORBING AEROSOLS (LAAS)(I.E. BLACK CARBON (BC) AND CERTAIN VARIETIES OF DUST) IN THE OVERLYING ATMOSPHERE OR ON THE SURFACE OF GREENLAND; THE PRESENCE OF ANTICYCLONIC BLOCKING ACTIVITY IN THE NORTH ATLANTIC; AND THE FORMATION OF LOW-LEVEL LIQUID CLOUDS (LLLCS) OVER THE GRIS SURFACE AMONG OTHERS. HOWEVER THE RELATIVE EXTENT TO WHICH EACH OF THESE PROCESSES COULD AFFECT SNOWMELT OF THE GRIS REQUIRES MORE EXPLORATION. IN THIS STUDY WE WILL USE A COUPLED ATMOSPHERE-SNOWPACK SINGLE COLUMN MODEL TO DIAGNOSE HOW LAAS BLOCKING EVENTS AND LLLCS COULD AFFECT GRIS SNOWMELT AND OTHER CLIMATIC FACTORS. THEN WE WILL COMPARE THE RESULTING MELT AND ENERGY FLUX BALANCES FOR EACH SCENARIO TO DETERMINE THE SENSITIVITY OF GREENLAND S CLIMATE SYSTEM TO EACH FACTOR. NOT ONLY CAN THIS ANALYSIS SERVE TO IDENTIFY THE MOST PREVALENT MEANS THROUGH WHICH SNOWMELT CAN OCCUR ON THE GRIS BUT IT CAN ALSO PROVIDE INSIGHT INTO THE SENSITIVITY OF THE GREENLAND CLIMATE AS THE PROPERTIES OF LAAS ANTICYCLONIC BLOCKING AND LLLCS ARE PERTURBED.
