Release of simulated MTG IRS Level 1B data package
Simulated Level 1B dataset of the Infrared Sounder (IRS), which will fly on Meteosat Third Generation sounding satellites (MTG-S), available for user familiarisation December 2019.
22 January 2021
12 December 2019
The dataset consists of a IRS dwell containing Level 1B spectra in native and Principle Component form, provided in netCDF format in line with the current IRS Level 0 and 1 Format Specification.
It is intended for format familiarisation and system testing.
The MTG IRS Level 1B dataset is delivered as a compressed tar file: IRS_L1b_Format_Familiarisation_2.2.tar.gz
The unpacked contents are:
- W_XX-EUMETSAT-Darmstadt,SND+SAT,MTS1+IRS-1B-SSS--Q1--CHK-BODY-- DIS-NC4E_C_EUMT_20191112155611_IDPFS_DEV_20160315120800_2016031512081 0_N__C_0049_0049.nc:
contains the noisy radiances and dwell geometry information encoded in the full L1B spectra format scaled as 2byte integers.
- W_XX-EUMETSAT-Darmstadt,SND+SAT,MTS1+IRS-1B-PC--Q1--CHK-BODY-- DIS-NC4E_C_EUMT_20191112154713_IDPFS_DEV_20160315120800_2016031512081 0_N__C_0049_0049.nc:
contains the above radiances re-encoded as principle components scaled as 4 byte integers, using the Eigen vectors and reconstruction operator provided in the following static support file.
