Microwave water-vapor correction for sea height (Sentinel-6A)

Sentinel-6A MF Jason-CS L2 Advanced Microwave Radiometer (AMR-C) NRT Geophysical Parameters
ocean NASA POCLOUD Level 2 netCDF-4
In plain English

What it measures. Atmospheric details like water vapor, wind speed, and how warm the surface looks in microwaves, used to fine-tune sea-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 3 hours.

How & where you'd use it. A correction product: it supplies the moisture and atmosphere adjustments that make the satellite's sea surface height measurements accurate, rather than being used on its own.

Official description

Provides L2 near real time (NRT; 3-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 NRT product is analogous to the Jason-3 OGDR product.
