Sentinel-1 L1 SLC (SAFE)

Provides Sentinel-1 L1 SLC Full Scenes data in SAFE format.


Introduction

This block provides medium-resolution Sentinel-1 SLC images. These images are acquired by the twin constellation Sentinel-1A and Sentinel-1B every 6 days anywhere on the globe. The datasets are available starting with 2014.
