Installing the CREW software package

Revision as of 14:31, 11 February 2014

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
unpack the software archive (for Linux use tar xfvj crewsoftware.tar.gz, for windows use some kind of zip software)
