Import NOOA's "GFS sflux" to Delft-FEWS

Dear community,

has anybody experience in importing (convective) precipitation from NOOA's "GFS sflux" to Delft-FEWS?

We would like to use these data because of the finer grid.

Precipitation is given as rates in (cycled) parameters Precipitation_rate_surface_1_Hour_Average,…, Precipitation_rate_surface_6_Hour_Average for the first 120h and as Precipitation_rate_surface_3_Hour_Average, Precipitation_rate_surface_6_Hour_Average for hours 123h - 384h.

Straight import using "cumulativeMean="true"" in externUnit leads to negative values.
During my search I've found the property <importTypeStandard>noaa_global_forecast_system</importTypeStandard> in the general section of an importRun.

Unfortunately I couldn't find any documentation concerning this.
Can anybody help?
        
Or I just have to stick to GFS 0.25.
        
Thanks in advance
Monika

Hi Monika, I have never imported this specific sflux paramer in Delft-FEWS, but do recognize issues with forecasts that have larger time steps for longer lead times. You could use the option interpolateSerie in the import module for this. See https://publicwiki.deltares.nl/display/FEWSDOC/Import+Module+configuration+options#ImportModuleconfigurationoptions-interpolateSerieNot sure if it applies to your situation though. If the data is stored in different files, you might want to import these forecasts individually and merge them together in FEWS with merge/simple transformation module.

Thanks Mathijs for answering.
I was actually looking for a way to avoid doing all that stuff explicitely by means of transformations.

So I still put hope into the import property
<importTypeStandard>noaa_global_forecast_system</importTypeStandard>
Has anybody experience or some documentation concerning this?
Just an addition: I want to import downloaded data (GRIB2) for archiving reasons.

Best regards
Monika
