Level 0.3 / Level 0.5 Data

Level 0.3 and Level 0.5 data are very similar. One could say that the Level 0.3 data is a temporary, best effort set of Level 0.5 data based on what is available at the time of computation.

In theory, after N days the Level 0.3 data will disappear from a given date and a person will only view the Level 0.5 data. The value of N is yet to be determined. It may be as low as 5 days. Essentially, Level 0.3 is intended to be "QuickLook" data, only desired by the user who needs data ASAP (as opposed to a science analyst user).

Sources for the Level 0.3/0.5 data include:

• Level 0.1 data (metadata and images from the instruments)
• Orbit prediction data from the GSFC Flight Dynamics Center
• Attitude data from the spacecraft
• Temperature and Power data from the spacecraft and instruments

Data series that feed Level 0.3/0.5 include:

sdo.*

Edit conflict - other version:

• sdo.fds
• sdo.fds_orbit_ingesthist
• sdo.fds_orbit_vectors (contains both helio- and geo-centric velocity) sdo.fds_orbit_vectors_sbox sdo.hk_dayfile (Prime keys – date, apid, source, also keyword source=moc. Contains all dayflies for all SDO APIDs from MOC product server) sdo.moc_fds sdo.ancillary_science_data

Functions intended to feed the Level 0.3/0.5 data series include:

• A drms module, getfdsorbit – input: time (something that is not on the original time grid, so interpolation will be necessary), coord system (also specifies helio or geo/J2000 ecliptic or something else or interpolation parameters); output: position vector and velocity vector. Make the output doubles. (Art) No need for an intermediate series with interpolated/converted data.
  1. Must change the master LZP MOC server download script, mocDlLzp.csh (JSOC/proj/lev0/scripts/mocserver), to download files to /surge, and then call script to ingest into sdo.hk_dayfile.
  2. The script/module to ingest into sdo.hk_dayfile must be created.
  1. Needs a sdo.asdp - Contains all the ancillary science data packet information (apid 129) (Jennifer).
     1. Need to write an ingest script/module for sdo.asdp.
     2. Input to this script is sdo.hk_dayfile.
  2. Need a master lev 0.3 record creation module. It calls modules like getfdsorbit.
