Three sequences of 30 seconds length each were simulated based on GLD360 and SEVIRI data from 20 June 2013, starting at 201306200700, 1500, and 1700, respectively. Several issues in an earlier 2020 release of LI L2 test data are fixed. The simulated test datasets were produced with the EUMETSAT LI reference processor, with high scientific and format representativity. MTG FCI Level 0 & 1 Format Specification, V4Cįormat Comparison between MTGTD-360 FCI L1C products and operational FCI L1C products Lightning Imager (LI)Ī new set of simulated Level 2 datasets for the Lightning Imager (LI) on MTG-I was released on 3 September 2021, for user familiarisation.The format for these test data is derived from: This test data contains 24 hours of FCI Level 1C FDHSI datasets to be used for product familiarisation. The compressed data has been generated using external HDF filters based on the CharLS compression (see the MTG FCI L1 Product User Guide for further information). The package contains compressed and uncompressed versions of the data. The radiances contained in the previous package were a plain copy of the SEVIRI channels, while this dataset contains simulated channels that are spectrally representative of the actual MTG FCI output, using the latest FCI spectral response functions. While both datasets have the same format specification baseline, the content is radically different. MTGTD-360 is an evolution to the previously delivered MTGTD-298 FCI 1C 26-Hour test data package that was released to users in October 2021. Released test data packages and support data Flexible Combined Imager (FCI) However, different test data can be associated with different user preparation processes, from tailoring of data acquisition systems to visualisation and utilisation of the satellite data in an operational environment. User test data can take different forms, for instance having more or less scientific values, formats and sizes. This is valid both for the pre-launch development period and during post-launch commissioning activities. Test data of that kind should have the best possible maturity in data content and in format specifications attached to different data. To ensure user readiness, it extremely important that users have access to data that will, in a best possible way, resemble the data that will be available from the future instruments.
