Thermal noise error

Microwave Toolbox Problem Reports
#1

For certain S1 IW data sets (see below for three examples) the thermal noise correction using SNAP 2.0 (latest release version) fails with the following error:

I am using an Intel Xeon running Windows 7 with 32 GB of RAM.

Example data sets where this error occurs:

  • S1A_IW_GRDH_1SDV_20151127T054147_20151127T054212_008786_00C874_C61C.SAFE

  • S1A_IW_GRDH_1SDV_20151125T042218_20151125T042243_008756_00C797_047A.SAFE

  • S1A_IW_GRDH_1SDV_20151124T233147_20151124T233212_008753_00C786_B5A6.SAFE

Thanks in advance!

Thank you for reporting the problem and listing the products. We’ll have
a look.

#3

Also S1A_IW_GRDH_1SDV_20151127T165110_20151127T165135_008793_00C8A5_C793

New release?

@simonf: It seems that the bug has already been fixed: https://senbox.atlassian.net/browse/SITBX-300
So I guess we need to wait for the next SNAP-version.
