Working with TLE-AUX

[markgreenman]

If I run ADL_Unpacker on H5 TLE products, it produces a file set per input H5 like:

TLE-AUX_npp_20120109162801Z_20120109000000Z_ee00000000000000Z_-_c3s-_ops_all-_ops.msd
TLE-AUX_npp_20120109162801Z_20120109000000Z_ee00000000000000Z_-_c3s-_ops_all-_ops.msd.CMP_FILENAME

the .msd file looks like a standard ASCII TLE. I see from the slides from the January 18-19 ADL workshop, presentation 'ADL 3.1 Workshop: Tools Demo' that since this is an Auxiliary Data, the ADL_Unpacker does an 'Unwrap'.

The Conversion to TLE-AUX-Int outlined on Page 33 of the presentation 'Running the CrIMSS Chain' is straightforward, add a space to each line in the '.msd' file.

1) What should the resulting naming pattern be for the TLE-AUX-Int file created?
2) The example copied an existing Metadata .asc file and edited it. What metadata fields should be updated, and to what should their values be set? For example, how is the 'Effectivity' time range determined for a given input TLE?

thanks,
Mark

The AUX file naming convention is specified in the CDFCB-X, Volume 1, Table 3.4.4-1.

Basically, you can copy "TLE-AUX_npp_20120109162801Z_20120109000000Z_ee00000000000000Z_-_c3s-_ops_all-_ops.msd", put a URID on the front, and replace "msd" with "txt_Internal". So it'd be "URID.TLE-AUX_npp_20120109162801Z_20120109000000Z_ee00000000000000Z_-_c3s-_ops_all-_ops.txt_Internal". You can use $ADL_HOME/tools/bin/UridCreator.exe to create a new URID.

Effectivity is taken from the file name. In your example of "TLE-AUX_npp_20120109162801Z_20120109000000Z_ee00000000000000Z_-_c3s-_ops_all-_ops.msd" :
--"20120109162801Z" is the Production Timestamp (2012-01-09 16:28:01Z)
--"20120109000000Z" is the Effectivity Start
--"ee00000000000000Z" is the Effectivity Stop (the "ee00000000000000Z" means the maximum IET time, which is 2038-01-19 03:14:07.000000. (See http://en.wikipedia.org/wiki/Year_2038_problem for a reason for that date)

The other time fields (RangeDateTime and ObservedDateTime) I would just leave as in the example I posted to your thread titled "CmnGEO-Anomaly-TLE" ("2000-05-18 14:00:30.000000" "2038-01-19 03:14:07.000000").

Thanks Kevin. This was consistent with what I was expecting/doing. Just wanted to ensure I was treating them correctly.
