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:

• Download and unpack the CREW software package
• Download and unpack the CREW common database
• Adjust a few startup files

If you like to compare SEVIRI against Atrain sensors, following packages has to be installed additionally:

• Download the AVACS software
• Create a database of reference datasets
• Use the CREW and AVACS software package in combination
