Within the CREW project a software package was developed for the inter-comparison and validation against CALIOP, CPR and AMSR-E data. The software package currently has a beta version status. We would like to invite every user to give us feedback to improve the software package. The functionality of the CREW software package includes:

  • displaying cloud properties on the SEVIRI disk or other user specified areas
  • histograms
  • latitudinal means
  • plotting cloud property against viewing zenith angle
  • scatter plots (SEVIRI algorithm A against SEVIRI algorithm B)
  • scatter plots (SEVIRI algorithm against CALIOP/CPR/AMSR-E)
  • multi algorithms ensemble means and standard devations
  • ISCCP type plots (frequency distribution in dependence of cloud optical thickness and cloud top pressure)
  • cross section plots along the ATRAIN tracks
  • Taylor diagrams

Several steps have to be completed before you can use the CREW software package if you like to intercompare SEVIRI retrievals:
1. Send us an email in order to register for the CREW project. 2. Download and unpack the CREW software package
3. Download and unpack the CREW common database
4. Adjust a few startup files
If you like to compare SEVIRI against Atrain sensors, following packages has to be installed additionally:
5. Download the AVACS software
6. Create a database of reference datasets
7. Use the CREW and AVACS software package in combination

Now all steps in more detail
1. Download an unpack the CREW software package
[crewsoftware.tar.gz ftp://ftp.icare.univ-lille1.fr/DATA/FS117/crew/software/crewsoftware.tar.gz]
unpack the software archive (for Linux use tar xfvj crewsoftware.tar.gz, for windows use some kind of zip software)
