Microwave humidity data for climate sea-level work (Copernicus)

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

What it measures. Provides carefully calibrated microwave brightness readings at three frequencies, used to gauge atmospheric water vapour that would otherwise distort satellite sea-level measurements.

How it's made. From the Sentinel-6 AMR-C radiometer, fully calibrated and released about 60 days later for the highest accuracy.

How & where you'd use it. A correction input for long-term climate studies of rising seas; supports reanalysis and reprocessing rather than everyday viewing.

Official description

The Sentinel-6 AMR-C Non Time Critical (NTC) product delivers high-precision, fully calibrated brightness temperature data at three microwave frequencies (18.7, 23.8, and 34.0 GHz). Optimised for long-term climate monitoring, the product enables accurate retrieval of wet tropospheric corrections and supports reanalysis and reprocessing applications. Data are structured by satellite passes and made available within 60 days of acquisition in NetCDF format.
