Continually check for daily water vapor images and update climatology

Function:

Continually check for daily water vapor images and update the daily climatology images. Place the daily image on the silo.

Parameters:

PROCESS(AUTO)

  = AUTO:    Continual automatic update
  = MANUAL:  Continual manual update

Example:

  1. LAS> upmeans_daemon-auto

    The procedure will run continually looking for TOVS water vapor images that appear in the ADAPSING directory. The daily and climatology for each image is updated with the new image values. Images found are moved to the silo.

  2. LAS> upmeans_daemon-manual

    The procedure will run continually looking for TOVS water vapor images that appear in the ADAPSPROD directory. The daily and climatology for each image is updated with the new image values. Images found are moved to the silo.

Description/Algorithm:

The UPMEANS_DAEMON continually searches for TOVS water vapor images that appear in either the ADAPSING or ADAPSPROD directories. The daily climatologies are updated with the values from the image. The image is placed in the proper directory on the silo. Images that encounter an error during processing are moved the ADAPSERR directory. Processing messages are logged in the ADAPSLOG directory to UPMEANS.LOG for AUTO processing and UPMEANS_MANUAL.LOG for MANUAL processing. Processing can be halted by placing the stop file UPMEANS_DAEMON.stop in the ADAPSTABLES directory.

Nonfatal Error Message:

  1. [upmeans-error] ERROR encountered in the upmeans procedure

    An error was encountered during processing. The error message preceding this one is the specific error encountered. The file being processed is moved to ADAPSERR. Processing will continue.

Fatal Error Messages:

  1. [upmeans-ustop] UPMEANS_DAEMON terminated by user

    The UPMEANS_DAEMON was signaled to stop by the user with the use of a stop file.

User Notes:

  1. UPMEANS_DAEMON enters an infinite loop to update the daily and monthly climatologies. To stop the procedure, run

    ADAPSTOP-FUNC FUNCNAM=UPMEANS_DAEMON

    If it is signaled to stop, UPMEANS_DAEMON will complete the image it is in the process of ingesting and terminate.
