Microwave humidity correction, medium-speed (Copernicus)

Sentinel-6 AMR-C Short Time Critical (STC)
land ESA ESA Copernicus active
In plain English

What it measures. Measures the atmosphere's microwave brightness to work out how much moisture is in the air along the satellite's path, which is needed to correct ocean-height readings.

How it's made. Generated by the Sentinel-6 AMR-C radiometer, calibrated and delivered within about 36 hours of measurement.

How & where you'd use it. Feeds ocean models and data-assimilation systems as a supporting correction; not a standalone product for general readers.

Official description

The Sentinel-6 AMR-C Short Time Critical (STC) product provides medium-latency, calibrated brightness temperature measurements, used to derive wet tropospheric path delay corrections with improved accuracy. Data are organised by full orbital passes and delivered within 36 hours of acquisition. The product supports ocean modelling and data assimilation workflows, and is provided in NetCDF format.
