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

File "/usr/local/cb/ocssw/scripts/", line 196, in <module>
  File "/usr/local/cb/ocssw/scripts/", line 189, in main
  File "/usr/local/cb/ocssw/scripts/modules/", line 491, in findweb
  File "/usr/local/cb/ocssw/scripts/modules/", 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.

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...
