RAP - Rapid Refresh
|Provider:||National Centers for Environmental Prediction, NOAA (USA)|
|Model scope:||North America|
|Update frequency:||every hour|
|Resolution:||0.117°, 7.0nm, 13.0km|
|Model duration:||21 forecasts starting at 1 hr, ending at 21 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:||Mon Apr 19 04:00:00 2021 UTC|
|Download date:||Mon Apr 19 05:13:58 2021 UTC|
|Download delay:||1hr 13min|
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.
RAP is a weather model NOAA runs hourly, producing short term forecasts. There are several RAP domains.
As RAP is a mesoscale model, it is able to model land and other features at a higher resolution than in a global model, leading to improved forecast accuracy.
