Chesapeake Bay Chlorophyll Concentration Data

by lydiaryeats » Sat Sep 07, 2024 4:58 pm America/New_York

Hello. I have been trying to access chlorophyll concentration data for the Chesapeake Bay. I went through the OB.DAAC Level 3 & 4 browser and extracted PACE-OCI data in a selected region. I then received my order and downloaded the HTTP file and was able to use the url from the HTTP file to download the tar file using wget command. I am now having trouble extracting my tar file. The file type is a 3 File. If you have any advice or suggestions as to how to extract this file, that would be greatly appreciated. Thank you.

I have not been able to recreate the issue you are describing. Would you mind sharing the whole name of the file you received if it was different from this:

requested_files.tar

Once you download requested_files.tar, you can extract them like this: tar -xvf requested_files.tar

Hello. Thanks for reaching out. I tried using the code that you provided to extract the files, but was unable to. I attached an image to this reply to show what happened when I tried to extract my file. My full file name is requested_files_1.tar@h=ocdist403&p=%2Fdata1%2F2040d000b1db6d6e%2Frequested_files.3

Thank you for your time.

The downloaded file should be named requested_files_1.tar. If it is "requested_files_1.tar@h=ocdist403&p=%2Fdata1%2F2040d000b1db6d6e%2Frequested_files.3" as your attachment indicates you passed to the tar command, it may be that you a) gave the tar command the wrong filename or b) the file was downloaded with the URL path included (which can happen if the client used to download doesn't honor the content-disposition header). If the former, run tar on the requested_files_1.tar file. If the later, try renaming the file before passing it to tar.
