Evaluation of the Navy Oceanic Vertical Aerosol Model Using Lidar and PMS Particle-Size Spectrometers
Abstract
The Navy Oceanic Vertical Aerosol Model (NOVAM) was evaluated by making nearly simultaneous measurements of atmospheric structure with an airborne lidar and Particle Measuring Systems, Inc., aerosol spectrometers. Profiles of measured aerosol-size distributions were scaled to the lidar returns, and the calculated extinction coefficients were compared with the NOVAM predictions. NOVAM predicted extinction coefficient profiles have similar structure to the aircraft-measured profiles but underestimate the absolute value. When scaled to visibility, good agreement exists between the measured and predicted profiles. Agreement between the predicted and measured extinction coefficients is strongly dependent on air mass factor.
