194	Support for TerraSAR-X	Dave Offiler	Dave Offiler	"Torsten Schmidt at GFZ has provided some example .dat/.dsc files containing TerraSAR-X (TSRX) data. Unfortunately, these are being written with subtle differences from the nominally same format used for CHAMP and GRACE-A. Torsten provided a modified gfz2ropp.f90 (from ROPP-3) which he has used to convert TSRX files to ROPP netCDF. He notes:

{{{
Some comments to the gfz2ropp program. I had to make some small
changes because the output from Georg Beyerle was not exactly
compatible with the GRACE data. 


The changes are in

line 493: comment out this line

line 499-502: my output goes to 'OUTPUT/', therefore 
""datfile(8:9)"" instead of datfile(1:2)

line 502: change of TX to TS

line 521/522: comment out. The program was interrupted at this line. 
I don't know why.


line 526/527: inserted, because Georg didn't wrote the azimuth 
angle in the file header, but in the dsc file.



I've attached the version I've changed.



Just to remember, I used ROPP Vers.3 for the results attached.


}}}

So that GFZ can use one version of gfz2ropp to convert NRT GRACE-A as well as test (and eventual NRT) TSRX data, a hybrid of the ROPP and GFZ versions is desirable. This has been done for v3.0 while investigating Ticket #193.

Having discussed with Huw, we agree the following plan:

1) Update gfz2ropp.f90 in ROPP Tag-3.0 (Marked v3.1 in the source Version string). Provide this version back to GFZ for re-compiling in their local ROPP-3 build. 

2) Edit the same changes into Trunk-4.0 (retain v4.0 in the source Version string) prior to ROPP-4 (v4.0) general release.
