ABSTRACT: Meteorological inputs are of great importance when implementing an air
quality prediction system. In this contribution, the Weather Research and
Forecast (WRF-ARW) model was used to compare the performance of the different
cumulus, microphysics and Planet Boundary Layer parameterizations over Bogotá,
Colombia. Surface observations were used for comparison and the evaluated
meteorological variables include temperature, wind speed and direction and
relative humidity. Differences between parameterizations were observed in
meteorological variables and Betts-Miller-Janjic, Morrison 2-moment and BouLac
schemes proved to be the best parameterizations for cumulus, microphysics and
PBL, respectively. As a complement to this study, a WRF-Large Eddy Simulation
was conducted in order to evaluate model results with finer horizontal
resolution for air quality purposes.
