Microwave water-vapor correction for sea height (Sentinel-6A)
What it measures. Atmospheric readings such as water vapor, wind speed, and microwave surface brightness, used to fine-tune sea surface height measurements.
How it's made. Produced from the Advanced Microwave Radiometer on the Sentinel-6A satellite and lined up with the radar altimeter's readings, delivered within about 36 hours.
How & where you'd use it. A correction product that supplies the moisture and atmosphere adjustments needed to make the satellite's sea-height measurements accurate, rather than being used directly.

Official description
Provides L2 short time critical (STC; 36-hour latency) geophysical information from the Advanced Microwave Radiometer on the Sentinel-6A Michael Freilich spacecraft including surface type, wind speed, water vapor, brightness temperature, sigma0, wet troposphere, and associated quality flags. The data are interpolated to intervals that correspond to altimetry measurements from the Poseidon-4 SAR to supply the geophysical and environmental corrections for altimetry. The S6A STC product is analogous to the Jason-3 IGDR product.
