This total neutral density data set from the San Marco D/L satellite Drag Balance Instrument (DBI) was provided by the PI team at the Centro Ricerche Aerospaziali in Rome, Italy. It contains the 1-second DBI data for the whole San Marco mission in ASCII format on CD (originally provide on 24 floppy diskettes). Each data file (file extension .D2) contains the time and the measured total density at that time for consecutive measurements. A new file is started any time there is a data gap of more than a few seconds. A corresponding file (.D1) contains information about the exact start and stop time of the specific measurement period, about the status of all experiments and other important information for the particular orbit, e.g., the Time of the Last Maneuver; this time parameter is important to sort out dynamically perturbed periods. Two high frequency filters and a filter for the satellite spin frequency were applied to clean the density data. Regular and irregular bias patterns were computed and recorded in the D1 files. 21-second averages of these data are generated using the PI-provided software to generate orbit parameters. The data are in ASCII format and each data record includes the date, time, total density, error, altitude, latitude, longitude, and local solar time.

This San Marco D/L Electric Field Experiment (EFI) data set was provided by the PI team on 12 magnetic tapes in ASCII format and constitutes the final EFI archiving product (filename: yymmddhhmm.dc). The data from the first tape are available online in this directory. The following parameters have been archived: (A) DC electric field (8 points per second) along the X and Y axes in spacecraft coordinates; (B) Variational (AC) electric fields averaged at 0.5 second intervals for all channels of each of the three spectrometers; (C) Some orbital parameters such as the altitude of the satellite, the geographic longitude and latitude, the local solar time and the dip latitude, and a day/night flag for the DC data; (D) Non- reduced plasma ion densities measured by the Ion Velocity Instrument (IVI). The DC portion of the EFI experiment is only valid for non-reduced IVI data > 2.5 volts corresponding roughly to an electron density of 10^4 electrons per cubic centimeter. Note that the AC data is valid at all plasma densities. More details can be found in the acformat_sfdu.txt and the voldesc_sfdu.txt files. Both of these files are ASCII text files.

This set of plasma data came from the Retarding Potential Analyzer and Ion Drift Meter instruments that constituted the San Marco Ion Velocitiy Investigation (IVI). The data were submitted by the PI team in ASCII format with SFDU Voldesc and Format description files. The data are provided as monthly files. Each data record contains the following parameters deduced from the IVI measurements: ion temperature, spacecraft potential, vertical and horizontal component of the ion velocity, total ion density, H+ ion density, O+ ion density, and the density of molecular ions. In addition the following parameters are included with each record: date, time, dip latitude, altitude, geographic longitude and latitude, solar local time, and solar zenith angle. The time resolution is approximately 10 seconds. The data have been screened for errors due to lack of appropriate vehicle orientation information or to failure of the least-squares analysis routine. More information about the satellite mission, the IVI experiment and the format of the data can be found in the voldesc and format files. Both files are ASCII text files.

This Level 1C data product measured over multiple scans on the disk contains data directly measure by the sensors such as photometer counts, uncertainties, light intensities and pointing information derived from the GUVI raw sensor data and the TIMED Satellite ephemeris data. The data are geolocated at a 150 km altitude, then gridded and binned to a 25 km X 25 km resolution GUVI-based coordinate system consisting of the along orbit position of the sensor and the angle of the scan from the nadir position. This gridding eliminates overlap from scan to scan due to the large instantaneous field-of-view of GUVI (about 12 degrees) and involves coaddition to place the values on a uniform instrument shared grid. The data is then determined whether its from day, night, aurora or twilight pixels.
