Data ingest and objective analysis for the PSU/NCAR modeling system: Programs DATAGRID and RAWINS

Report discusses in detail the auxiliary programs DATAGRID and RAWINS, and intends to update previous documentation for these two programs (Haagenson, 1987; Seaman and Haagenson, 1985). The purpose of this document is threefold: 1.) to provide users of the PSU/NCAR modeling system with an overview of the methods used in DATAGRID and RAWINS; 2.) to provide users with some instructions for running DATAGRID and RAWINS; 3.) to provide users with reference material about the codes of DATAGRID and RAWINS, in case users desire to modify the programs for their own purposes. Section II of this document discusses some of the design requirements of the forecast model, and introduces certain conventions and definitions which are used throughout the document. Sections III and IV discuss DATAGRID and RAWINS individually. Each of Sections III and IV provides a description of the purpose and methods of the program; second, information needed to use the program; and third, a discussion of the details of the code itself. The discussion of DATAGRID (Section III) includes an additional discussion of an auxiliary program which may need to be run in conjunction with the DATAGRID program.
