GRIB Model

NAM - North American Mesoscale Forecast System


Provider:National Centers for Environmental Prediction, NOAA (USA)
Model scope:North America
Update frequency:every 6 hours
Resolution:0.108°, 6.5nm, 12.0km
Model duration:35 forecasts starting at 0 hr, ending at 3 days 12 hrs
Parameters:pressure, wind, wind gust, rain, cloud, temperature, humidity, dew point, convection, vorticity, vertical velocity, simulated radar, precipitable water, visibility, 0C isotherm, 250 mb, 500 mb, 850 mb
GRIB model date:Thu Mar 28 06:00:00 2024 UTC
Download date:Thu Mar 28 08:56:03 2024 UTC
Download delay:2hr 56min

Note: the Download delay is the amount of time required for the GRIB model to compute its forecast and then for the LuckGrib cluster to download the data and make it available. The LuckGrib delay is generally less than 10 minutes, the remainder of the delay is the model compute time.

Description

NAM is one of NOAA’s major weather models, which in this case covers most of North America. NAM is a mesoscale model, which means that the numerical analysis is able to model land, and other features, at a higher resolution than in a global model, leading to improved forecast accuracy.
