Abstract:
Over the past year she has made significant progress on her project. She has begun the modeling work discussed in her APERG application with a commercial program (FACSIMILIE). She has conducted an extensive literature search and compiled various chemical mechanisms to build a reaction system that uses 300+ gas-phase, aqueous-phase and phase transfer reactions set-up as differential equations. She has obtained preliminary results demonstrating that some low vapor pressure products (oxalic acid and pyruvic acid) are formed during “cloud processing” of isoprene. Her program is currently set-up to have one cloud for three hours a day every day for seven days. This and other simplifying assumptions have been used in her model (e.g., constant boundary layer height in the atmosphere) are set at reasonable values (i.e., values typically found to exist in the environment). She hopes to incorporate a sinusoidal variation in UV, dependent on time and solar zenith angle into the model. She has also begun to work on laboratory validation experiments.
