Abstract
The FIDUCEO Microwave Fundamental Climate data record, v4.1, contains microwave brightness temperatures and uncertainties for series of satellite instruments (all mission years of SSMT2 on F11, F12, F14, F15; AMSU-B on NOAA15, NOAA16 and NOAA17; and MHS missions (NOAA18, NOAA19, MetopA,-B)). The presented FCDR is a long data record of increased consistency among the instruments compared to the operational data record and is a long enough data record to generate climate data records (CDRs) for climate research. The improvements are based on the strict application of the measurement equation as well as dedicated corrections and improvements within the calibration process. The data record contains quantified uncertainty components, respecting the correlation behaviour of underlying effects.

| File Format: |
NetCDF fiuduceo format see documentation for
- Basic telemetry: longitude, latitude, time, satellite and solar angles (these angles are not provide for SSMT-2);
- Brightness temperatures for channels 1-5;
-Independent, structured and common uncertainty for channels 1-5;
-for each scan line: original scan line number of the l1b files
- for each scan line: indicator which l1b file it belongs to
-8 bitfields indicating identified problems with the data: one bitmask indicating level of trust in the data (per pixel and scanline), one bitmaks indicating sensor specific quality issues (per pixel and scanline); one bitmask indicating quality issues per scan line, i.e. transmitter status so far (per scanline), 5 bitmasks indicating certain quality issues for each channel (per pixel and per scanline)
The dimensions of the variables in the NetCDF file are x and y, indicating the pixel and scan line, respectively. Additionally, there are the dimensions channel and n_frequencies, denoting the number of channels and the number of frequencies (for which Spectral Response Function is defined).
