Data Set Overview : The Juno MWR EDR data sets will ultimately include all uncalibrated MWR science data records for the entire Juno mission. This volume will contain only those data obtained during the orbital phase of the Juno mission, when this phase of the mission is completed. These data com- prise the raw data that address the primary objectives of the Juno  mission. They consist of data obtained at the full MWR data rate during a five-hour period around each perijove pass, and data obtained at all other times for the purpose of instrument calibration and perform- ance monitoring. This volume consists of reformatted and uncalibrated  data records. The reformatting operation reassembles received instrument data packets into one-hour-long records of time-ordered data correspond- ing to 100-ms observations made by the MWR instrument. This data set is intended to preserve the full content of the uncalibrated instrument  packets and is to be used only as a last resort. The level 3 MWR  archived data are designed to be complete and more easily used. The primary usefulness of these data lay in preserving the inputs to higher level calibrated data sets so that such sets may be regenerated in the event that better calibrations become available or in the event that mistakes are uncovered in the data processing pipelines. In either event the MWR instrument team is intended as the user of these data, *not* the wider scientific community. Parameters : The fundamental unit of this data set comprises the data obtained during a single 100-ms observation made by the MWR instrument. Each observation does not include all of the MWR instrument parameters required for its calibration, some of which must be interpolated from neighboring observations. Actually producing calibrated data from these raw data requires detailed knowledge of the MWR instrument. Processing : The data included in this volume were processed by the EDR processing pipeline as described in section 2.3 of the VOLSIS document found under the DOCUMENTS subdirectory. In short, this pipeline consists of programs which reassemble fragmented packets, decompress packets and check for CRC errors. Data : Products in this data set consist of files of time-ordered data corresponding to observations of 100-ms duration each. These are received from the instrument in time-contiguous units of ten observations each, with one unit then corresponding to one second's worth of observation. Successive units may be contiguous in time (full data rate) or separated by n seconds each (reduced data rate). These units are then assembled into contiguous files of one hour length regardless of data rate. Each IRDR and GRDR file has its associated label file, which in total comprise one data record. The details of the collection and formatting of these files is described in Sections 2 and 3, and in Appendix B, of the VOLSIS document found under the DOCUMENTS subdirectory. Ancillary Data : This data set is complete, although the generation of higher level calibrated data from this raw data set requires the SPICE toolkit and Juno mission SPICE kernels from the Navigation and Ancillary Information Facility (NAIF) along with calibration data from pre-launch measurements and cruise. Coordinate Systems : As these are raw data they are recorded without reference to any coordinate system. Pointing information is contained in the level 3 data (specifically, in the geolocation reduced data records, or GRDRs). Software : No software is provided to view, interpret, or convert this data set. All files are in ASCII format, however, and are readily readible through standard programs such as textedit, Microwave Excel and Word, etc. Media/Format : This data set is provided to the Planetary Data System by the Juno Science Operation Center (JSOC) as described in section 5.2 of the VOLSIS document found under the DOCUMENTS subdirectory.

Confidence Level Overview : This data set contains all instrument packets for the Juno MWR experiment for the interval described in the labels for the individual product files. Every effort has been made to ensure that all data returned to the Juno Science Operations Center from the spacecraft are included, even those packets which fail checksum tests. Review : The MWR raw complete data will be reviewed internally by the Juno MWR instrument team prior to release to the PDS. The data set will also be reviewed by the PDS. Data Coverage and Quality : TBD Limitations : Limitations on the data set may be defined as the MWR team gains experience operating the instrument in flight conditions. No limitations are presently known.
