The data collection contains daily calibrated Level 2 binary files, derived from the Low Frequency Receiver (LFR) and High Frequency Receiver (HFR) of STEREO-A/Waves and STEREO-B/Waves spacecraft.


The collection is composed of daily binary files, which content is described in [REF].

The file naming convention is: STx_WAV_rrr_yyyymmdd.B3E

  • x: a 1-letter code for the spacecraft in use (A=STEREO-A; B=STEREO-B);
  • rrr: receiver in use (LFR or HFR).
  • yyyy: Year in 4 digits
  • mm: Month in 2 digits (0-padded)
  • dd: Day in 2 digits (0-padded)

Coverage and sampling

  • Time range:
    • 2006 to now for STEREO-A
    • 2006 to 2014 for STEREO-B
  • Time resolution: 30 seconds to 2 minutes.
  • Spectral range: 2.5 kHz to 15 MHz


The STEREO/Waves L2 data collection has been produced by X Bonnin, QN Nugyen, M Maksimovic (LESIA/Observatoire de Paris-PSL), with the support of CNRS, CNES and B Cecconi and L Debisschop (PADC/MASER).

BC and LD were also supported by PADC and EPN2024-RI. The Europlanet 2024 Research Infrastructure (EPN2024-RI) project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 871149.
