Subsetting issue on Windows

[imcslatte]

I've installed Herbie on a Windows 10 machine running python 3.10. My objective is to generate regional subsets of surface met variables (ugrd,vgrd,tmp at 2m,sfcpress , etc) for use as forcing for a regional ocean model. The first step is to subset the data by variable.

I stared with a simple example from the tutorial

from herbie.archive import Herbie
H = Herbie('2022-7-12 00:00',product='sfc',source='aws')

✅ Found ┊ model=hrrr ┊ product=sfc ┊ 2022-Jul-12 00:00 UTC F00 ┊ GRIB2 @ aws ┊ IDX @ `aws`

searchstring=':TMP:2 m'
H.read_idx(searchstring)

	grib_message	start_byte	end_byte	range	reference_time	valid_time	variable	level	forecast_time	search_this
71	36433970	37698543	36433970-37698543	2022-07-12	2022-07-12	TMP	2 m above ground	anl	:TMP:2 m above ground:anl

H.download(verbose=True)

✅ Success! Downloaded HRRR from local               
	src: C:\Users\Eli Hunter\data\hrrr\20220712\hrrr.t00z.wrfsfcf00.grib2
	dst: C:\Users\Eli Hunter\data\hrrr\20220712\hrrr.t00z.wrfsfcf00.grib2
WindowsPath('C:/Users/Eli Hunter/data/hrrr/20220712/hrrr.t00z.wrfsfcf00.grib2')

Downloading the entire file works fine. It appears in my home directory as expected.

However, when I try this:

H.download(searchstring,verbose=True)

📇 Download subset: ▌▌Herbie HRRR model sfc product initialized 2022-Jul-12 00:00 UTC F00 ┊ source=local

💾 Saved the subset to C:\Users\Eli Hunter\data\hrrr\20220712\subset_b7103ca278a75cad8f7d065acda0c2e80da0b7dc__hrrr.t00z.wrfsfcf00.grib2
WindowsPath('C:/Users/Eli Hunter/data/hrrr/20220712/subset_b7103ca278a75cad8f7d065acda0c2e80da0b7dc__hrrr.t00z.wrfsfcf00.grib2')

The output suggests a subset file was downloaded and is now in my home directory. However, the file subset_b7103ca278a75cad8f7d065acda0c2e80da0b7dc__hrrr.t00z.wrfsfcf00.grib2 does not exist. And it was instantaneous. There did not seem to be any delay associated with a file download.

Is there a configurations step I am missing?

Thanks.,
Eli

I just tried this on Linux and didn't have an issue. I have both these files in my ~/data/hrrr/20220712 directory.

hrrr.t00z.wrfsfcf00.grib2 
subset_b7103ca278a75cad8f7d065acda0c2e80da0b7dc__hrrr.t00z.wrfsfcf00.grib2

I'll have to try it on my PC to see if I can reproduce your issue.

I wasn't able to reproduce your issue on my Windows

And both files appear in the file explorer

What do you get when you execute

H.xarray(searchstring)

you should get the 2-m temperature data read into an xarray DataSet
