Eta model at 80 and 22km resolution, eight times a day, over two regions of different extent, was run during South America Low level jet experiment. These runs, when compared against radiosonde measurements of winds, moisture and temperature profiles, allow identification of model biases related to resolution and model description of the diurnal cycle. The presentation explores the ability of the model to regionally downscale large scale features and its potential use for regional climate assessments based on its performance over this particular season of enhanced observations.
