Running COMP_ASC_DES


The following steps are needed to run COMP_ASC_DES - the executable that combine orbital gridded files into global daily fields.

---

1. Run one or more orbits through CLAVRXORB and produce orbital gridded files (*.cell.hdf).

---

2.  Create a comp_asc_des_input file to hold the names of files to process and input/output paths.  Put it in $CLAVRXHOME.

COMP_ASC_DES looks for files to process from the list and paths contained in the comp_asc_des_input file.  An example is listed below.

Line 1 is the directory housing the  orbital cell files
Line 2 is the directory that will contain the output daily asc/des cell files
Line 3 is the year of the desired daily fields
Line 4 is the Julian day of the desired daily fields
Line 5 is the satellite number to use for these fields
Line 6 is the expected grid resolution (obsolate but included based on OSDPD request)
Line 7 is the expected grid format (obsolete but included based on OSDPD request)
Line 8-XX are the names of the orbital files to process (14 per day)

Here is an example
/data4/patmosx/2003/orbital/
/data4/patmosx/2003/daily/
2003
190
16
0.5

NSS.GHRR.NL.D03190.S0054.E0248.B1439899.WI.cell.hdf

3. Additional Comments

• comp_asc_des will take the global attributes from the first file and apply them to final file.  It will look for conflicts.  Therefore, the grid format and resolution of the first orbital file read in, determines the value assumed for the final daily file.  Orbital files that do not conform are rejected.

4. Running COMP_ASC_DES

To run COMP_ASC_DES, simple run the executable (comp_asc_des) in the $CLAVRX_HOME directory.  COMP_ASC_DES will read the comp_asc_des_input file and  take the appropriate actions.  Currently, there are no command line arguments.
