A Final Analysis of the Comparison Between Theoretical and Observed Estimates of Broadband Absorptance During ARESE II
O'Hirok, W. and Gautier, C., University of California, Santa Barbara
Twelfth Atmospheric Radiation Measurement (ARM) Science Team Meeting
The ARM Enhanced Shortwave Experiment (ARESE) II was conducted in spring 2000 to address unresolved issues about the absorption of solar radiation in the atmosphere in the presence of clouds. In a preliminary study comparing 3-D radiative transfer model computations with observations, we found that for the heaviest overcast condition the discrepancy in the near-infrared absorptance could not be explained. In this study, we again compare observations made from flight and ground levels with theory using more refined estimates of aerosols, surface reflectance, cloud and atmospheric conditions. Additionally, we conduct a more extensive sensitivity analysis and look for possible explanations for the observed discrepancy in the near-infrared region.
