ACC












                                                 Requesting Specific ACC Data



    The Mission Time Line (csv) can be used to select time intervals of interest. This file contains geometry parameters that are associated with the periapse of each orbit and supporting notes that will be updated and enhanced over time.

    Data Type

    The data products are simple ASCII tables.

    The data consist of a file for each periapsis passage and give start time and stop time and consist of tables that contain seconds from periapse, areodetic latitude, east longitude, local solar time, solar zenith (deg.), areodetic altitude (km), and 2 density averages (90 second and 1 second) with corresponding sigmas in (KG/KM**3).

    Data can be retrieved in 3 Ways:
    1. Download the whole data set. (22 MB)

    2. An index (csv) that can be used for planning data selection is available. It tabulates information associated with each periapsis passage for which accelerometer data was derived. The associated geometry is given at the time of periapsis passage. This file can be edited and URN values submitted using the this option.

    3. Data can be retrieved by selecting among the following parameters
