The NOAA2EPSL1B set of tools is a collection of programs that can be used to generate and verify simulated EPS ATOVS level 1b products using NOAA K, L and M level 1b products as input.
This is a set of Fortran 90 routines that can be used in other programs to read the contents of various EPS products formatted according to the EPS Native format. These routines will currently read data from the following EPS products: ATOVS L1B (MHS, HIRS, AMSU), AVHRR L1B, GRAS L1B, IASI L1C, ATOVS L2, IASI L2.
Kai is a tool for processing EPS PFS format products. It has several functions: To split a full sized product into non-overlapping 3-minute chunks, simulating the PDUs produced in the EPS Ground Segment; To combine PDUs or other fragments of products together into a large product; To manipulate products at the record level by selectively adding or removing records; To repair certain format errors in existing products; As a basic viewer to display the complete MPHR, SPHR, IPR, GEADR, VEADR and VIADR-L0-OBT2UTC records, and the generic record headers for all other records.
The pfs2xml tool, written in Visual Basic, has been developed to convert EPS Product Format Specifications (RD1 - RD11) from Microsoft Excel tables into XML (RD12) descriptions. The XML descriptions have the advantage of being highly consistent and can be easily used by tools such as Eugene to read and manipulate EPS products.
IDL, the Interactive Data Language software is ideal for data analysis, visualisation, and cross-platform application development. Many of the built in features of IDL are designed specifically for remote sensing applications. IDL has been selected to read, process, and analyse the EPS products. The EPS Product IDL Readers are able to process multiple versions of the product format, and due to its object-oriented design makes them ideal for application development.
Rectified (Level 1.5) Meteosat SEVIRI image data transmitted as Low Rate transmissions, in 5 spectral channels. Level 1.5 image data corresponds to the geolocated and radiometrically pre-processed image data, ready for further processing, e.g. the extraction of meteorological products. Any spacecraft specific effects have been removed, and in particular, linearisation and equalisation of the image radiometry has been performed for all SEVIRI channels. The on-board blackbody data has been processed. Both radiometric and geometric quality control information is included. The Low Rate data are sub-sets of data or data sets compressed by higher factors.
The Metopizer is a collection of tools for manipulating Metop CCSDS, CADU and t-VCDU packets and for generating EPS L0 products. Also included are viewers to display text dumps of all packets, and for extracting images from ATOVS, AVHRR and IASI source packets. The latest version of the Metopizer includes a Python module for reading sensor data from EPS L0 ATOVS and AVHRR products into Python scripts.
The main objective of the Infrared Atmospheric Sounding Interferometer (IASI) is to provide high resolution atmospheric emission spectra to derive temperature and humidity profiles with high spectral and vertical resolution and accuracy. Additionally it is used for the determination of trace gases such as ozone, nitrous oxide, carbon dioxide and methane, as well as land and sea surface temperature, emissivity and cloud properties. The IASI Principal component residuals product are the differences between IASI radiance spectra (see the IASI GDS L1C), and the same spectra compressed by the Principal Component Analysis method (see the IASI Principal component scores). By combining the noise-reduced spectra reconstructed from the principal component scores with the principal component residuals, one obtains radiance spectra identical to the original ones to within the quantisation step.
