About RPW data release philosophy

RPW public data are released on daily basis. Only L0/L1/L2 data older than 90 days are freely accessible. Any new version of a already published data file is made available without latency.

The release notes below only concern public data products, which have been impacted by a full re-processing (i.e., except for the first delivery on September 2020, "release" and "re-processing" terms are equivalent in these notes). Only main changes relevant for the science community are reported for each products. For a detailed modification history (including technical updates), please read the RCS software changelog in ROC gitlab site (restricted access).


Any new data file is generated with a version number "V01". This number is only incremented each time a new version of the file is required. (It means that for a given release and data product, public files can hence have different version numbers.)

RPW L2 science data release notes

September 2020

First public release of RPW science data (survey data only, no SBM data).

Initial versions of software used to generated science data (L2) were:

  • THR_CALBAR V2.2.3
  • TDS_CALBA V0.9.6
  • LFR_CALBUT V1.3.0
  • SCMCAL V0.12.1
  • BICAS V3.1.0

N.B. List of RPW data products w.r.t. to software can be found in RPW Data Products

March 2021

First full re-processing of RPW L0/L1/L2 data (survey data only, no SBM data).

Data productChange log (deltas since the previous release)Software nameSoftware version
SOLO_L2_RPW-TNR-SURV
  • NEW calibration procedure -- factor 2 in the voltage V0 (input voltage for the calibration)
  • Corrections on max/min in gattrs writing; remove gattrs1 from antennas_params
  • Variable FREQUENCY added
THR_CALBAR2.3.3
SOLO_L2_RPW-HFR-SURV
  • NEW calibration procedure -- added 2 dB to V0 due to the 75 ohm cable as observed in the BW test on ground
THR_CALBAR2.3.3
SOLO_L2_RPW-LFR-SURV-ASM
  • Reads the validity file from each team to obtain the calibration filename to use.
LFR_CALBUT1.5.5
SOLO_L2_RPW-LFR-SURV-BP1
  • Calibration improved.
  • Now BP1 are divided by ASM frequencies.
  • Days with only burst mode are now correctly computed.
  • Reads the validity file from each team to obtain the calibration filename to use.
LFR_CALBUT1.5.5
SOLO_L2_RPW-LFR-SURV-BP2
  • Calibration improved at F2 frequencies. Now BP1 are divided by ASM frequencies.
  • Days with only burst mode are now correctly computed.
  • Reads the validity file from each team to obtain the calibration filename to use.
LFR_CALBUT1.5.5
SOLO_L1R_RPW-LFR-SURV-CWF-B, SOLO_L1R_RPW-LFR-SURV-SWF-B
  • Update Global Attributes.
LFR_CALBUT1.5.5
SOLO_L1R_RPW-LFR-SURV-CWF-E, SOLO_L1R_RPW-LFR-SURV-SWF-E
  • No update
LFR_CALBUT1.5.5
SOLO_L2_RPW-LFR-SURV-CWF-E, SOLO_L2_RPW-LFR-SURV-SWF-E
  • Zero order AC data de-trending (remove mean; previously removed linear fit), but no AC data re-trending. This removes earlier artificial offsets and artificial linear components, in particular in snapshots.
  • Using improved fits and extrapolations of the BIAS AC transfer functions, in particular for low frequencies.
  • Using modified inverted transfer functions for AC data below 7 Hz (constant gain) to prevent low frequency noise from being amplified.
  • Sets quality variables based on manually identified thruster firings.
  • Better CDF standards compliance.
BICAS5.0.0
SOLO_L2_RPW-TDS-SURV-STAT, SOLO_L2_RPW-TDS-SURV-MAMP, SOLO_L2_RPW-TDS-SURV-HIST1D, SOLO_L2_RPW-TDS-SURV-HIST2D, SOLO_L2_RPW-TDS-SURV-RSWF-E, SOLO_L2_RPW-TDS-SURV-TSWF-E
  • 1.0.2 - Bug in CHANNEL_OVERFLOW flag for waveform snapshots fixed. Antenna lengths for RPW_ANTENNA_RTN data in snapshot waveforms added. Now both directions in RTN and effective lengths are provided.
  • 1.0.1 - Feature to process the resized L1 files for the redundant LFM modes implemented.
  • 1.0.0 - New calibration table released. A major problem in calibrations of MAMP, STAT, HISTxD fixed (mismatch in a calibration table). CHANNEL_CONFIG replaced by CHANNEL_REF in all concerning data products. TDS antenna configuration is now represented by number (e.g. 10 = ANT1-GND or 23 = ANT2-ANT3). Feature to process the resized L1 files implemented.
  • 0.9.9 - Signs for waveform and voltage snapshots fixed. Some issues with the ISTP/SPDF compliance resolved, metadata variables added dimensions for existing zVars changed.
  • 0.9.8 - Mandatory Global Attributes filled. Mismatch in modes for the waveform snapshot calibration fixed. Time vector in MAMP product adequately created.
  • 0.9.6 - the first SOAR release (known bugs: bad sign for VOLTAGES in all waveform snapshots. Bad calibrations for MAMP and STAT for some of the TDS modes. Incorrect time vector for MAMP. BAD flag for CHANNEL_OVERFLOW in MAMP, TSWF and RSWF data products).
TDS_CALBA1.0.2
