JERS-1_L1·v1·dataset
Raw radar that sees through clouds (JERS-1)
JERS-1 Level 0 Product
land NASA ASF Level 0
In plain English
What it measures. The earliest, unprocessed radar signals from the JERS-1 satellite — raw data before it has been turned into usable images. Radar can see the surface through clouds and at night.
How it's made. Recorded directly by the radar instrument on Japan's JERS-1 satellite as Level 0 (rawest) data.
How & where you'd use it. A raw building-block input: it needs heavy processing into images before most people can use it, so it serves specialists who generate higher-level radar products.
