Incorrect precipitations data in GRIB (possibly new NOAA version)
Posted: 19 Jun 2019 14:42
Since 13.7. precips forecast data are unusable. Total Precipitation values looks like being cumulated and not 3hr-interval computed.
How to reproduce the issue: choose any location in the App, show the meteotable e.g. or chart and watch the precip values. After the first nonzero value all other hour/intervals is "cumulating" the precip value from the previous date/time. By this you can see that sometimes even there is nearly 0 (zero) cloud cover, precipitation value shows e.g. 5mm/h and other funny results...
I would like to know whether it's a problem with data on Zygrib server or on NOAA side (maybe they changed something)?
Can we expect a fix?
PS. It's probably due to the change of the Upgraded GFS with FV3 core which starts around 12.6.2019
