Abstract
INTERMEDIATE ALTITUDE (\50-100 KM) NUCLEAR EVENTS PRODUCE A STRONG SHOCK. THE MATERIAL HEATED BY THIS SHOCK RADIATES IN MANY IR MOLECULAR BANDS. ACCURATE MODELING OF THE IR EMISSION IS POSSIBLE ONLY IF THE GAS STRUCTURE NEAR THE SHOCK CAN BE DETERMINED. A NUMERICAL HYDRODYNAMICS CODE THAT USES A DYNAMICAL ADAPTIVE GRID (DAG) CAN GIVE HIGH SPATIAL RESOLUTION NEAR THE SHOCK WHILE THE SHOCK PROPAGATES OVER LARGE DISTANCES, WITHOUT REQUIRING LARGE AMOUNTS OF COMPUTER TIME. WE PROPOSE TO WRITE AN APADTIVE GRID CODE THAT IS DESIGNED SPECIFICALLY TO CALCULATE THE QUANTITITES OF INTEREST FOR MODELING IR MOLECULAR BANDS. THIS COULD LATER BE INCLUDED IN THE ROSCOE CODE (OR ITS DERIVATIVES) TO YIELD IMPROVED MODELS OF IR EMISSION.
