HRRR public data?

[Andrew Stoller]

Does NOAA now have a delay for public HRRR data? I've noticed all this season that the HRRR runs are several hours delayed compared to previous years, and some days, it just flat out doesn't work with data missing or only going out like 3 hours. Thoughts??? Thanks!

I've mostly stopped using the NOAA site for that reason. The COD site is more reliable, in fact I haven't yet seen a missing, delayed or incomplete run there.

The data is current - the HRRR NOAA website is lagged. A lot.

CoD is pretty timely, but only has a small set of products. I prefer the ESRL/GSD site when available. Unfortunately I got a lot of 503 errors during the heart of chase season. Many more products available plus access to experimental and parallel runs. Not quite as fast as CoD, though.

The CoD site uses the NCEP low resolution HRRR data that comes over NOAAport I believe. The NOAA site may be using the HRRRx which is why it seems to not be there half the time. It seems to just run whenever it wants and most of the time not at all.

NOAA uses both and both are way behind the data. WxBell has full resolution HRRRx freely available on their site too.

Excellent. Thanks! The java loop doesn't work, but the display is current and has zoomed in graphics for many states/geographic zones.

I stopped using rapidrefresh.noaa.gov as well - it's by far the slowest and most unreliable. Here are a few alternatives:
Fast: http://weather.cod.edu/forecast/
Faster: http://www.spc.noaa.gov/exper/hrrr/
Fastest: http://mag.ncep.noaa.gov/model-guid...group=Model Guidance&model=HRRR&area=CENT-US#

FWIW we also have relatively fast-updating HRRR graphics on OWxData, a model site my friends and I started earlier this year. Images usually start posting about 45 to 50 minutes after the hour (e.g., 1:50pm for the 18z run). We hope to expand the number of products at some point, but for now it covers most of the essentials for chasers.

I talked to the people at HRRR HQ and they hope to have that time lag reduced (but no timeline for a fix.)
