GOME-2 Products Guide - Data Viewing and Reading

5.1 EPSView for data reading

(For this issue of the GOME Product Guide, the information provided on EPSView is generic for all EPS instruments. When the User's Guide of this tool is available, the following paragraphs will be replaced by a reference to it, and specific information about the use of EPSView for GOME-2 products inspection will be included in this product guide instead)

EPSView is a flexible, highly portable and easy-to-install visualisation and analysis tool for EPS products generated at EUMETSAT, to be used by EUMETSAT in the inspection, verification and characterisation of EPS System data and products. The tool is provided free-of-charge to the EPS end-users for familiarisation and handling of EPS data.

It is a portable tool, running on many different platforms, primarily Solaris, HP, AIX, Linux, Windows NT/XP, MAC OS X, IRIX. EPSView has a unique graphical user interface through which the user can easily access all the functionality required.

The following functionality can be provided by EPSView:

Production of ASCII files with the contents of the input products or a sub-set of them; export of input products contents into GIF, TIFF and JPEG image formats; export of a given data structure or group of structures of the input data for analysis into IDL; access to any data structure and decomposition of the contents down to the bit level.

Display in ASCII/HEX the contents of any data structure or section within the input products; display colour images and allow for zooming of user-selected image regions; display of latitude and longitude pixel information on the image interactively; visualisation of individual image channels as grey-level images; visualisation of coast-lines and rivers into map-projected displayed images; display of geolocation information of a cursor-selected pixel; display of 2-D plots of user-selected product fields and parameters, either temporal, spectra, scatter plots or vertical profiles; display of vector plots and other more complex plotting, e.g., 3-D plots and contouring.

5.2 BEAT for data reading

The Basic Envisat Atmospheric Toolbox (BEAT) provides a set of tools for ingesting, processing and analysing atmospheric remote sensing data. The primary instruments supported by BEAT are GOMOS, MIPAS and SCIAMACHY (flown on the Envisat satellite). However, BEAT also supports access to data from a wide range of other atmospheric instruments like GOME-2.

BEAT consists of several modules. These modules can be applications, libraries, interfaces to existing applications (such as IDL and MATLAB), or interfaces to other programming languages (such as Fortran and Python).

BEAT is provided by Science & Technology BV and can be downloaded free for non-commercial use via the following link: http://www.science-and-technology.nl/beat/.
