How to download 1 Hz GNSS VTEC data?

Posted: Sat Sep 13, 2025 10:22 am America/New_York

Hello,
I would like to download high-resolution Total Electron Content (TEC) data, for example with a 1 Hz sampling rate. Is there any website or database that provides such data directly, or do I need to process raw GNSS observation files (RINEX) to obtain it?
Thank you for your help!
