The error message is clear:
NOT FOUND for url: https://datapool.asf.alaska.edu/SLC/SA/S1A_IW_SLC__1SDV_20170324T011358_20170324T011425_015827_01A12B_940F%20%20%20%20.zip
The scene cannot be found because its identifier ends with a set of whitespaces ('...940F%20%20%20%20.zip'). You need to fix the scene names.
How to correct the scene ID link ?
I have just copied the scene ID from ASF but i do not how to clear the whitespaces "NOT FOUND for url: https://datapool.asf.alaska.edu/SLC/SA/S1A_IW_SLC__1SDV_20170324T011358_20170324T011425_015827_01A12B_940F%20%20%20%20.zip"
Check for any invisible whitespace characters (tiling) and remove them.
Hi Alexey,
I have a problem with downloading ASF data.
I am trying to run one of your Google Colab Notebook: https://colab.research.google.com/drive/1TARVTB7z8goZyEVDRWyTAKJpyuqZxzW2?usp=sharing
At cell [16], I am receiving this error:

I am also receiving the same error when I try download different scenes with SUBSWATH=123 option.
Do you have any idea what might be the problem?
Thanks in advance
The error is pretty clear:
ERROR: Downloaded incomplete scene content
You suffer from a network error or issue at the ASF datastore. Run the cell again or relaunch the entire notebook to continue the downloading.

Hi Alexey,
Thank you for the quick response.
I tried downloading one swath at a time using:
print(asf.download_scenes(DATADIR, SCENES, 1))
print(asf.download_scenes(DATADIR, SCENES, 2))
print(asf.download_scenes(DATADIR, SCENES, 3))
and the problem is resolved now.
Nice. FYI, this is not related to the number of swaths but only a temporary downloading error. PyGMTSAR example notebooks can produce such errors once or even for hours when an unpredictable network connection issue arises or the ASF datastore is in a maintenance state.
Set these variables to None and you will be prompted to enter your username and password below.
asf = ASF(asf_username, asf_password)
Optimized scene downloading from ASF - only the required subswaths and polarizations.
print(asf.download_scenes(DATADIR, SCENES, SUBSWATH))
There are two ways to download orbits; you can use any one or both together.
try:
RESORB orbit downloading from ASF has recently failed.
except Exception as e: print (e)
Download missed orbits in case ASF orbit downloading fails.
