Installing the CREW software package
From CrewWiki
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. Download and unpack the CREW software package 2. Download and unpack the CREW common database 3. Adjust a few startup files If you like to compare SEVIRI against Atrain sensors, following packages has to be installed additionally: 4. Download the AVACS software 5. Create a database of reference datasets 6. Use the CREW and AVACS software package in combination
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)
