HRRR 48hr - High Resolution Rapid Refresh
|Provider:||National Centers for Environmental Prediction, NOAA (USA)|
|Model scope:||North America|
|Update frequency:||every 6 hours|
|Model duration:||29 forecasts starting at 0 hr, ending at 2 days|
|Parameters:||pressure, wind, wind gust, rain, cloud, temperature, humidity, dew point, convection, smoke, simulated radar, precipitable water, lightning, visibility, 0C isotherm, 250 mb, 500 mb, 850 mb|
|GRIB model date:||Tue May 24 18:00:00 2022 UTC|
|Download date:||Tue May 24 20:05:05 2022 UTC|
|Download delay:||2hr 05min|
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.
This extended, 48 hour version of HRRR offers all of the parameters available in the main HRRR model.
The HRRR model is run every hour. Normally, the HRRR model runs generate forecast data for 18 hours. Four of the model runs each day generate additional forecasts, out to 48 hours.
This model is updated from the main HRRR model, however this version of HRRR only updates for the model cycles where there is extended forecast model data.
This model is updated for the model runs: 00Z, 06Z, 12Z and 18Z.
It takes roughly 1hr 50min after the model cycle time, the reference times above, for the data to become available.
