ACOLITE forum

Acolite is crashing when trying to read ancillary files such as MET/2022/141/N202214100_O3_AURAOMI_24h.hdf with the following error.

pyhdf.error.HDF4Error: SD (15): File is supported, must be either hdf, cdf, netcdf

This is not specific to Acolite I am also having this issue with Polymer, but I was wondering if anyone else is experiencing this or has found a solution?

Hi James

Indeed it seems like the ancillary data used in ACOLITE (NCEPR2 and AURAOMI) are no longer available from the oceandata server. I will have to investigate a change of file type or data source. For the moment please use ancillary_data=False

Hi James

I have adapted the ancillary data process to use GMAO MERRA2 or FP data. Please update your ACOLITE distribution and give it a try!

For processing imagery older than about six weeks, use the (new default) setting:
and for NRT data you can use:
I hope this helps!

Thanks Quinten for the super fast updates! I will run some tests with the updated code and get back to you if there are any issues.

Thanks for your work!

Hi Binbin

Did you update the code? Which error do you get?

Quinten

Dear Quinten,

My error same as the title"HDF errors with ancillary data"
I just used the ACOLITE20221114, but i can not find which script contain "ancillary_type=GMAO_MERRA2_MET", I check /ancillary get.py, there are nothing about ancillary types. Could you provide a new one?

Best, Binbin

Hi Binbin

The new code is not present in older versions... You must use a current git clone to be able to use the new ancillary format.

I may work on a new binary release in the coming weeks.

Quinten

Dear Quinten,

Thank you for your reply. I am looking foward new version.
