This is a repetition of the distribution of FCI L1c test data which took place in February-March this year, to allow users to test FCI data reception via EUMETCast, processing, system load and display, until actual FCI data become available.

The simulated MTG FCI L1 test dataset is identical to the May 2022 release of simulated FCI test data (Ref.: MTGTD-360, MTG test data and Dataset Description). It contains 24 hours of simulated FCI L1c full-disc channels at normal resolution, that are spectrally representative of the actual MTG FCI output, using the latest spectral response functions. The dataset only contains the compressed version of the data.

In terms of data volumes, please note that the compressed MTGTD-360 dataset is significantly smaller (factor 4-5) than what is expected from real compressed FCI spectra. This may compromise its use for system load testing. The reasons are that, due to the simulation, the MTGTD-360 dataset has (i) some missing or zero values near the edge of the disc, and (ii) smoother, less noisy characteristics than real spectra would have. Both factors give rise to more efficient compression of the data.

Format differences between the MTGTD-360 format specification and the version of the FCI L1 ground segment (IDPF-I) used at the start of FCI commissioning is documented in Format Comparison between MTGTD-360 FCI L1C products and operational FCI L1C products.
