Hi @edsml-ds42. Sorry for the slight delay in answering, I just got back from holidays.
I think you are looking at different products:
To get the file you directly downloaded, you need to specify product="IMERG-FR", product_type = "RS"
.
To download IMERG Early Run, you need to specify product="IMERG-ER", product_type = "NRT"
.
Note that you can download data from either storage="PPS"
or storage="GES_DISC"
.
Currently, I can already tell you that if you try downloading IMERG from GES_DISC
you will likely download duplicates files (one for version V07A and V07B). This might cause problems in gpm.open_dataset
. This problem occurs because they are updating IMERG products to version V07B these days .... then I guess they will delete version V07A and the problem will solve.
Hi @ghiggi,
No worries at all!
Thanks for pointing that out, all makes sense. I want the Early Run and I am currently using:
product="IMERG-ER", product_type = "NRT", storage="PPS"
so should be good.
Glad I could help @edsml-ds423 ;) Have a nice day !
Is there an existing issue for this?
Current Behavior
Hi,
First of all, I want to just say great job on the
gpm-api
. I was previously getting IMERG V07B data via FTPS in Python but moving forward, I might migrate and use your API.Before doing so I wanted to just sense check the downloaded data. I could be missing something but I did a test on the timeslice 27th September 20:00-20:30. To do so, I downoloaded the file via your api and I downloaded the file directly from
https://arthurhouhttps.pps.eosdis.nasa.gov/gpmdata/2022/09/27/imerg/
. I then checked the data.I found a mismatch between the values and if I plot a cropped region containing Hurricane Ian (peak intensity at the chosen timeslice), you can visually see the difference.
The two files that I am comparing are:
gpm-api
:3B-HHR-E.MS.MRG.3IMERG.20220927-S200000-E202959.1200.V07B
direct download:
3B-HHR.MS.MRG.3IMERG.20220927-S200000-E202959.1200.V07B.HDF5
Can I ask what server are you getting the version 7 files from?
Thanks, Dan
Expected Behavior
I was expecting the API and directly downloaded data to match exactly.
