issues with MODIS Aqua and Harmony failing

[clifgray]

Hello, I've been trying to subset and download older MODIS-Aqua ocean color data for a very small spatial area, but whether I do it in python or in the EarthData GUI it consistently fails. I can work with PACE OCI data but not MODIS-Aqua. Anna Windle at OEL has reproduced this same error, and we both get: " Error in file '/worker/podaac/subsetter/subset.py', line 437, in function 'subset': Could not determine time variable" " and eventually the request fails after a few retrys.

This seems similar to issues faced in the past by other users:
viewtopic.php?t=7013
viewtopic.php?t=6870

For reference the request I'm sending with harmony-py (and basically exactly following https://nasa.github.io/oceandata-notebooks/notebooks/oci/subsetting_with_harmony-py.html) is:

request = Request(
collection=Collection(id="MODISA_L2_OC"),
spatial=BBox(-136.31748, 58.6961, -136.0904, 58.740),
temporal={"start": datetime(2003, 6, 1), "stop": datetime(2003, 6, 30)},
variables=["geophysical_data/Rrs_443", "geophysical_data/Rrs_555", "geophysical_data/l2_flags"],
pixel_subset=True,
labels=request.labels,
)

Is there anything I can do to workaround this or is there any chance of updating this reader to correctly find the time variable. It is in those files but I think has a different format.

Cheers,
Patrick

Hello,

Some updates have been made over the past couple of months. I just tried submitting an order using the parameters you provided, and it went through successfully.

Please give it another try and let us know if the issue persists.
