Raw radar that sees through clouds (RADARSAT-1)

RADARSAT-1 Level 0 Product
land NASA ASF Level 0
In plain English

What it measures. Raw radar measurements of Earth's surface from a satellite that can see day or night and through clouds, organized into fixed map-defined frames across the globe.

How it's made. Collected by the synthetic aperture radar on the RADARSAT-1 satellite and kept at Level 0, the earliest, unprocessed stage.

How & where you'd use it. A raw building-block input rather than a finished product; it is used to create higher-level results such as interferograms, which can reveal ground movement.

Official description

RADARSAT-1 SAR data processed to fixed frames defined by latitude and longitude for the globe. The Level 0 products can be used as inputs to create higher-level products, such as interferograms
