General Description 1.1. Overview This Software Interface Specification (SIS) describes Radio Science Occultation Summary (OCCSUM) data files from the Mars Global Surveyor (MGS) Mission. OCCSUM files were created at Stanford University and contained results of processing MGS radio occultation data to obtain the structure of Mars' atmosphere [1]. OCCSUM files contained summaries of results from one or more Radio Occultation Temperature-Pressure (RSTP) data files. The MGS Mission was managed by the Jet Propulsion Laboratory (JPL) for the National Aeronautics and Space Administration (NASA). 1.2. Scope The format and content specifications in this SIS apply to all phases of the MGS Mission for which the OCCSUM was produced. OCCSUM products covered by this SIS include those at both standard (approximately 200 m vertical) resolution and high (approximately 20 m vertical) resolution. 1.3.

Interface Location and Medium OCCSUM files were created by the Stanford Mars Global Surveyor Radio Science processing system, which consisted of Sun SPARC-Ultra workstations and associated peripherals. 1.4.2. Data Sources, Transfer Methods, and Destinations OCCSUM files were created by the Stanford MGS Radio Science processing system. OCCSUM files were distributed electronically via the Stanford MGS Radio Science server and were written to Compact Disc (CD) write-once (WO) media for archive with the Planetary Data System (PDS). 1.4.3. Generation Method and Frequency OCCSUM products were generated by extracting and reformatting information contained in keyword and data headers on RSTP files [2]. Each OCCSUM file contained data from one or more occultation events; a typical OCCSUM contained data from occultation events over a period of one month. Separate OCCSUM files were created for standard and high-resolution RSTP files. OCCSUMs were generated when the data for the appropriate orbits become available, were processed, and had been staged for delivery. 1.5. Assumptions and Constraints 1.5.1. Usage Constraints None. 1.5.2. Priority Phasing Constraints None. 1.5.3. Explicit and Derived Constraints None. 1.5.4. Documentation Conventions 1.5.4.1. Data Format Descriptions The reference data unit is the byte. Data may be stored in fields with various sizes and formats, viz. one-, two-, and four-byte binary integers, four- and eight-byte binary floating-point numbers, and character strings. Data are identified throughout this document as char 8 bits character uchar 8 bits integer short 16 bits integer long 32 bits integer float 32 bits floating point (sign, exponent, and mantissa) double 64 bits floating point (sign, exponent, and mantissa) u (prefix) unsigned (as with ulong for unsigned 32-bit integer) other special data structures such as time, date, etc. which are described within this document If a field is described as containing n bytes of ASCII character string data, this implies that the leftmost (lowest numbered) byte contains the first character, the next lowest byte contains the second character, and so forth. An array of n elements is written as array[n]; the first element is array[0], and the last is array[n-1]. Array[n][m] describes an n x m element array, with first element array[0][0], second element array[0][1], and so forth. Floating point (real) numbers are represented in ASCII using the FORTRAN E or F formats. Fixed point (integer) numbers are represented using the FORTRAN I2 or I5 format. 1.5.4.2. Time Standards OCCSUM files used the January 1.5, 2000 epoch as the standard time. Within the data files, all times were reported in Universal Coordinated Time (UTC) as strings of 23 ASCII characters. The time format is "YYYY-MM-DDThh:mm:ss.fff", where "-", "T", ":", and "." are fixed delimiters; "YYYY" is the year "19nn" or "20nn"; "MM" is a two-digit month of year; "DD" is a two-digit day of month; "T" separates the date and time segments of the string; "hh" is hour of day; "mm" is the minutes of hour (00-59); "ss" is the seconds of hour (00-59); and "fff" is in milliseconds. Optional suffix "Z" explicitly indicates use of the UTC reference. The date format is "YYYY-MM-DD", where the components are defined as above. 1.5.4.3. Coordinate Systems The OCCSUM used the areocentric fixed body coordinate system [3]. 1.5.4.4. Limits of This Document This document applies only to OCCSUM data files. 1.5.4.5. Typographic Conventions This document has been formatted for simple electronic file transfer and display. Line lengths are limited to 80 ASCII characters, including line delimiters. No special fonts or structures are included within the file. Constant width characters are assumed for display. 2. Interface Characteristics 2.1. Hardware Characteristics and Limitations 2.1.1. Special Equipment and Device Interfaces OCCSUM files were created on the Stanford MGS Science Operations Planning Computer (SOPC) using ASCII formats. They were stored in electronic form on the Stanford MGS Radio Science server and on CD-WO media. 2.1.2. Special Setup Requirements None. 2.2. Volume and Size OCCSUM products have variable length, depending on the number of occultation events included in the file. The summary information for each occultation occupies 324 bytes. The file size is the product of the record length times the number of events included in the file. For 300 occultations (approximately the number expected from one month) the OCCSUM file size would be 97200 bytes for either standard or high resolution profiles. 2.3. Labeling and Identification Each file has a name which describes its contents. The name includes the following structure which uniquely identifies it among Mars Global Surveyor Radio Science products: YMMymmZZ.OCx where Y is the least significant digit of the year of the first entry in the OCCSUM file, MM is the two-digit month of the first entry in the OCCSUM file. y is the least significant digit of the year of the last entry in the OCCSUM file, mm is the two-digit month of the last entry in the OCCSUM file. ZZ is a two-character string indicating the version of the OCCSUM file. x indicates the resolution of the source files "S" is for standard "H" is for high-resolution, Each OCCSUM file is accompanied by a detached PDS label, which is a file in its own right. The label file associated with YMMymmZZ.OCx has the name YMMymmZZ.LBL. 2.4. Interface Medium Characteristics OCCSUM products are electronic files or files written to CD-WO. 2.5. Failure Protection, Detection, and Recovery Procedures None. 2.6. End-of-File Conventions End of file labeling conforms to standards for the medium on which the OCCSUM file is stored. 3. Access 3.1. Programs Using the Interface Data contained in OCCSUM files will be accessed by programs at the home institutions of Mars Global Surveyor and other investigators. Those programs cannot be identified here. 3.2. Synchronization Considerations 3.2.1. Timing and Sequencing Considerations N/A 3.2.2. Effective Duration N/A 3.2.3. Priority Interrupts None. 3.3. Input/Output Protocols, Calling Sequences None. 4. Detailed Interface Specifications 4.1. Structure and Organization Overview The OCCSUM is a file generated by MGS Radio Science data reduction and analysis software at Stanford University. It conforms to Planetary Data System standards [4,5]. Each OCCSUM file is accompanied by a detached PDS label. 4.2 Detached PDS Label The detached PDS label has two parts -- a header and body. The header contains information about the origin of the file and its general characteristics such as record type and size. The body is a complete bit-level definition of the OCCSUM file. Each OCCSUM detached PDS label is constructed of ASCII records; each record contains exactly 80 characters. The last two characters in each record are the carriage-return (ASCII 13) and line-feed (ASCII 10) characters. 4.2.1 Label Header The structure of the label file header is illustrated in Figure 4-2. An example of a complete label file is given in Appendix A. |====================================================================| | | | Figure 4-2.
