Ancillary Data for MODIS

by avmehta » Sun Dec 13, 2020 11:04 am America/New_York

Hello,
  I am converting Aqua MODIS data from L1 to L2. For the atmospheric correction I get ancillary data using getanc.py.
  Everything worked fine for years 2012 to 2020. But for 2011 I get the following errors:

File "/usr/local/cb/ocssw/scripts/getanc.py", line 196, in <module>
    sys.exit(main())
  File "/usr/local/cb/ocssw/scripts/getanc.py", line 189, in main
    g.findweb()
  File "/usr/local/cb/ocssw/scripts/modules/anc_utils.py", line 491, in findweb
    ancdatabase.openDB()
  File "/usr/local/cb/ocssw/scripts/modules/ancDB.py", line 18, in openDB
    conn = sqlite3.connect(self.dbfile, timeout=30)
sqlite3.OperationalError: unable to open database file


I'd appreciate your help with this.
Thank you.
Best,
Amita

Amita,

The getanc script needs to be able to read and write to the sqlite database file "$OCVARROOT/ancillary_data.db" (unless you give it another name with the --ancdb option)
For some reason, yours is not able to be opened.  You need to figure out why...
