Hi everyone! I have two problems to process MODIS-Aq images in L1.
The first problem is to generate the GEO files for some images.  The error is:

*** ERROR: The HTTP transfer failed with status code 3.
*** Please check your network connection and for the existence of the remote file:
*** http://oceandata.sci.gsfc.nasa.gov/Ancillary/Attitude-Ephemeris/2011/163/PM1ATTNR.P2011163.1600.*
***
*** Also check to make sure you have write permissions under:
*** /seadas6.2/run/var/modis/atteph/
*** If you cannot obtain write permissions here you can set up your own atteph
*** directory by copying the seadas.env_user_bash or seadas.env_user_csh file
*** into your ~/.seadas/ directory and editing the MODIS_ATTEPH line.

*Failed to determine/retrieve required definitive attitude and ephemeris files*
*Falling back to predicted attitude/ephemeris*

Determining required predicted attitude and ephemeris files...
/seadas6.2/run/scripts/modis_predicted_atteph.csh 2011163163000 2011163163459

Checking local hard disk for required real-time attitude and ephemeris files...
Missing on hard disk: Predicted attitude file corresponding to pass start time.
Missing on hard disk: Predicted attitude file corresponding to pass stop time.
Missing on hard disk: Predicted ephemeris file corresponding to pass start time.
Missing on hard disk: Predicted ephemeris file corresponding to pass stop time.

WARNING: IF YOU ABORT, MAKE SURE TO REMOVE THE PARTIALLY DOWNLOADED FILES

*** No real-time attitude file corresponding to pass start time exists on http site. Exiting.

*Failed to determine/retrieve required predicted attitude and ephemeris files*

The required attitude and ephemeris files are not available!
Processing cannot proceed.

Nevertheless, I can generate GEO file for other images (Ex. A2010025162500).
The second problem is to process L1B to L2. The error is:

Downloading S201002512_NCEP.MET

*** ERROR: The HTTP transfer failed with status code 3.
*** Please check your network connection and for the existence of the remote file:
*** http://oceandata.sci.gsfc.nasa.gov/cgi/getfile/S201002512_NCEP.MET
***
*** Also check to make sure you have write permissions under the directory:
*** /seadas6.2/run/var/anc/
***
*** If you cannot obtain write permissions here you can set up your own ancillary
*** directory by copying the seadas.env_user_bash or seadas.env_user_csh file
*** into your ~/.seadas/ directory and editing the USER_L2GEN_ANC line.

How can I resolve these problems? Any advice??
Thank you in advance!

Laura -

Sorry it took so long to respond.

This looks like a temporary network interruption.  Were you ever able to retrieve those files and process your data?
