How to process GACOS data for InSAR Atmospheric Correction?

07 July 2019 1 1K Report

Hello,

I am trying to apply GACOS service to correct atmospheric artifacts on InSAR interferogram.

I downloaded the GACOS_Ultility folder to test the proposed example. However, I found some troubles to adapt it to my InSAR data. Did anyone succeed to process the GACOS correction for their InSAR interefrograms?

Thank you.

Hi,

An example MATLAB code and ReadMe file are provided at http://ceg-research.ncl.ac.uk/v2/gacos/

I find the read me file more useful. You can implement a simple MATLAB program following the document. We corrected for tropospheric errors in DInSAR results using GACOS ZTD maps. Please refer to our recent publication available in RG about surface displacements of the 2017 Iran-Iraq earthquake.

If you are working with GMTSAR, there is a code available, which can be used to correct atmospheric errors using GACOS ZTD maps. Please search the GMTSAR forums.
