Process AVHRR images ready to be archived
ARCHIVE will identify and process AVHRR images which are ready to be archived.
- SCEOSACQ("NOA")
- Selective acquisitions. The list of CEOS stations for which a tape copy must be made. The scenes to be copied to the tape are selected according to a list found in ADAPSTABLES. For example, if SCEOSACQ="esa", then the list "select;esa" found in ADAPSTABLES will specify which acquisitions are to be copied to the tape for ESA.
- UCEOSACQ("SFL")
- Unconditional acquisitions. The list of CEOS stations for which a tape copy must be made. All individual acquisitions from all CEOS stations will be copied to this tape.
- SCEOSORB("BJG")
- Selective orbital segments. The list of CEOS stations for which a tape copy must be made. The scenes to be copied to the tape are selected according to a list found in ADAPSTABLES. For example, if SCEOSORB="esa", then the list "selectorb;esa" found in ADAPSTABLES will specify which acquisitions are to be copied to the tape for ESA.
- UCEOSORB("SFL")
- Unconditional orbital segments. The list of CEOS stations for which a tape copy must be made. All orbital segments from all CEOS stations will be copied to this tape.
ARCHIVE will look in the ADAPSARC directory. For each AVHRR Level-0 acquisition image that it finds, it will (1) copy the image to the subdirectory [esa.sfl] under ADAPSARC (if the CEOS ID of the image is present in the 'select;esa' table), (2) copy the image to the subdirectory [noa.sfl] under ADAPSARC (if the CEOS ID of the image is present in the 'select;noa' table, (3) copy the image to the subdirectory [sfl.sfl] under ADAPSARC, and (4) move the image to the subdirectory [prodgen] under ADAPSARC. If the image is an AVHRR Level-0 orbital segment, it will (1) copy the image to the subdirectory [esa.km1] under ADAPSARC (if the CEOS ID of the segment is present in the 'selectorb;esa' table), (2) copy the image to the subdirectory [bjg.km1] under ADAPSARC (if the CEOS ID of the segment is present in the 'selectorb;bjg' table), (3) copy the image to the subdirectory [sfl.km1] under ADAPSARC, and (4) move the image to the subdirectory [prodgen] under ADAPSARC. Error diagnostics and processing messages will be logged in 'archive;log' within ADAPSLOG.
ARCHIVE looks for Level-0 AVHRR images residing in the ADAPSARC directory. When an image is found, the following steps are performed: For each image found, lock it so that another instance of ARCHIVE does not try to also process it. For each image found, iterate through all of the specified conditional copying needed (copies the image only if the appropriate 'select' file contains the images CEOS ID). For example, if the user specified SCEOSACQ = 'esa', and the file 'select;esa' within ADAPSTABLES contains the CEOS ID of the image, then the image will be copied to the [esa.sfl] subdirectory within ADAPSARC. ARCHIVE then iterates through all of the unconditional copying needed (copies the image to the user specified directories). For example, if the user specified UCEOSACQ = 'sfl', then the image will be copied to the [sfl.sfl] subdirectory within ADAPSARC. ARCHIVE then moves the image to the [prodgen] subdirectory within ADAPSARC. The image is unlocked, and ARCHIVE looks for another image to process.
A fatal error was encountered during processing. The error message displayed immediately preceding this message is the specific error encountered.
An error was encountered while returning the FOUNDFLG parameter to TAE. Contact the system administrator.
An error was encountered while returning the variable block to TAE. Contact the system administrator.
An error occurred while trying to determine the value of the environment variable ADAPSTABLES. Ensure that this variable has been defined.
The specified selective copy file could not be opened. Ensure that the file exists, and with the proper permissions.
An error was encountered while reading from the specified file. Ensure that the file format is correct (see User Note).
ARCHIVE was terminated by the user.
An error was encountered while determining the name of the stop file. Ensure that ADAPSTABLES has been defined.
An error was encountered while determining if the stop file exists. Contact the system administrator if this error persists.
An error was encountered while determining if an AVHRR image exists for processing. Contact the system administrator if this error persists.
An error was encountered while attempting to lock the AVHRR image prior to processing it. Contact the system administrator if this error persists.
An error was encountered while processing the AVHRR image(s) in the 'selective' loop. Contact the system administrator if this error persists.
An error was encountered while processing the AVHRR image(s) in the 'unconditional' loop. Contact the system administrator if this error persists.
ARCHIVE was unable to move the image into the 'prodgen' subdirectory. Ensure that the directory exists with the appropriate permissions.
An error was encountered while attempting to unlock the AVHRR image after processing it. Contact the system administrator if this error persists.
ARCHIVE was aborted by the user.
