The CloudSat Operational and Research Environment (CORE) is a software package designed to facilitate data processing tasks involving multiple operations performed on an evolving data set by one or more processing algorithms. It's primary functions are to integrate the algorithms into one software package for ordered execution and to be the common handler for data used and produced by the algorithms. CORE is written in Fortran 90 and compiled with the Compaq Visual Fortran (CVF) compiler on the Windows 2000 operating system.
The code that is compiled to form the CORE executable can be separated into two groups: one group of routines that define the framework of CORE and another group that includes custom data manipulation modules. The modules contained in the second group can be removed from or inserted into the CORE framework and define the specific data processing capabilities of CORE. The data manipulation modules can be further separated to include file I/O routines, science algorithms, data re-mapping routines, and common utility routines.
