Smos data time series analysis

hi team,
I’m trying to do time series analysis for smos data, but while doing the stack process i’m getting error,


sir how can i solve this error and is there any steps to include in the process.

thank you in advance.

Maybe you should use SMOS toolbox? http://step.esa.int/main/download/

can’t we do in SNAP?

No, this is currently not possible.
The SMOS-BOX has no time-series support and the Create Stack function of S1TBX does not handle SMOS correctly.
Time series support will be enhanced in the future of SNAP but at the moment it is not possible, unfortunately.
