The North American Mesoscale Model (NAM), formerly known as Eta, refers to the numerical weather prediction model run by National Centers for Environmental Prediction for short-term weather forecasting. Currently, the Weather Research and Forecasting (WRF) model is run as the NAM, thus, both names (NAM or WRF) refer to the same model output. The model is run four times a day (00, 06, 12, 18 UTC) out to 84 hours. It is currently run with 12 km horizontal resolution, providing finer detail than other operational forecast models.
