Van Allen Probe B Spectrogram Data
Listed in NASA Data Portal
This data set contains Level 2 wave electric field and search coil wave magnetic fields spectral data from the Electric Field and Waves Suite (EFW) onboard Van Allen Probe B. Spectrograms between ~40 Hz and ~8 kHz are calculated on-board the EFW instrument every 4 seconds.
Description
These data include one component of the ac-coupled electric field from the rotating V12 sensors (V12ac). The electric field quantity is labeled EFW/L2.
Also included are two components of the wave magnetic field from the University of Iowa EMFISIS sensors. The search coil quantities are labeled EFW/L2 spec64 smu. In the labels "smu" and "smv", the suffixes "u" and "v" refer to the u and v sensor coordinates rotating with the spacecraft.

All these quantities, the nature of the on board signal processing, their filtering, time resolution and their respective coordinate systems are described in the EFW instrument paper (Wygant et al. 2013). When the spectral CDF is opened, many other possible quantities are listed which have no data in them. Possible sources include:
- E12dc
- E34dc
- E56dc
- E12ac
- E34ac
- E56ac
- E DC parallel
- E DC perpendicular 1
- E DC perpendicular 2
- E AC parallel
- E AC perpendicular 1
- E AC perpendicular 2
- V1+V2+V3+V4/4AC
- SCMu
- SCMv
- SCMw
- SCM parallel
- SCM perpendicular 1
- SCM perpendicular 2 Those without data are "place holder quantities" which are used by other instrument modes not currently selected. Examples of the spectral data may be found in Principal Investigator's on-line survey data plots. EMFISIS instrument wave data may be found on the University of Iowa website. This includes valuable spectral electric field data up to 400 kHz and magnetic field data up to about ~6 kHz.
