title: Van Allen Probe A Electric Field and Waves Suite (EFW) Burst Waveform VB1 Medium Resolution Electric Potential in Spacecraft Spin (UVW) Coordinates and Instrument Status, Level 1 (L1), 1.95 ms Data

description: The EFW Burst Modes provide targeted Measurements over Brief Time Intervals of 3-D Electric Fields, 3-D Wave Magnetic Fields, and Spacecraft Potential. There are two EFW Burst Modes: BURST1, B1, Medium-Rate 512 samples/s nominal and BURST2, B2, Higher-Rate, 16384 samples/s nominal. The Burst 1 Mode Data includes three components of the Electric Field, E12_B1, E34_B1, and E56_B1, six Components of the Spacecraft Sensor Potential, V1_B1 through V6_B1, and three Components of the AC Magnetic Field, SCM_U_B1, SCM_V_B1, and SCM_W_B1, from the EMFISIS Search Coil Magnetometer. The Burst 2 Mode Data returns a similar Complement of Electric Field, E_12ac_B2, E34ac_B2, and E56ac_B2, Search Coil, SCM_B2, SCM_2B2, and SCM_B2, again from the EMFISIS Search Coil Magnetometer and Single-ended Potential Measurements, V1ac_B1 through V6ac_B2, with the exception that in the Default Mode the Single-ended Potential and Electric Field Signals are AC coupled with a higher Gain. All Quantities are in UVW Coordinates where, U, and, V, are the Sensor Coordinates rotating with the Spacecraft and, W, points along the Spacecraft Spin Axis. Burst Waveform CDF Files are available. The three Data Types available are the Electric Field, E, the Searchcoil Magnetic Field, MSC, and Antenna Potential, V. The Suffix on each of these is either, B1 or B2. B1 or Burst 1 is the Human-in-the-Loop Burst Type, meaning that both Collection and Playback for arbitrary Lengths of Time are requested on the Ground. B2 or Burst 2 is automatically telemetered as short Bursts based on an onboard Triggering Algorithm, typically set to trigger on large Amplitude Signals near 1 kHz. Sample Rates for B1 and B2 can and are changed depending on varying Science Goals.

title: Van Allen Probe A Electric Fields and Waves (EFW) 32 sample/sec despun electric field in modified-GSE (MGSE) coordinates

description: These high time resolution de-spun data are EFW measurements of the spin plane electric field at 32 samples/s. These data are presented in the MGSE system. Special care should be taken in its use. The EFW instrument can be sensitive to the low energy plasma environment and spacecraft effects in ways that other instruments are not. Users should read the "RBSP/EFW Data Required Reading" document for more details. In addition, mismatches between the responses of the different probes can introduce error signals. A preliminary check of the quality of this data may be carried out by comparing the rotated 32 sample/s electric field in the high time resolution CDF to the spin fit data found in the spin fit CDFs. In order to carry out this comparison the high time resolution data should be averaged down to the spin period to eliminate the higher frequency turbulence.

title: Van Allen Probe A EFW Filterbank Data

description: This data set contains Level 2 filterbank data from the Electric Field and Waves Suite (EFW) onboard Van Allen Probe A. Average power and peak amplitudes from either 7 (default) or 13 logarithmically spaced band-pass filters are measured between 0.8 Hz and 6.5 kHz sampled at a cadence of 8 samples/s. Two sources may be input into the filter banks at any one time. The possible sources include:.E12DC,E34DC,E56DC,.E12AC,E34AC,E56AC,.SCMU,SCMV,SCMW.(V1DC+V2DC+V3DC+V4DC)/4. In the default mode, V12ac, the AC coupled measurement of the electric field from sensors 1 and 2 in the spin plane is input into the first filter bank and SCMw, the spin axis component of the search coil magnetic field, serves as input into the second filter bank. The broadband filters provide a continuous stream of survey mode measurements over the entire orbit providing information on rapid time variations and bursty wave activity over a broad frequency spectrum. These measurements are also used as an input to burst trigger algorithms. 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).

title: Van Allen Probe A Spectrogram Data

description: 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 A. Spectrograms between ~40 Hz and ~8 kHz are calculated on-board the EFW instrument every 4 seconds. 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.

title: Van Allen Probe A Spinfit DC Electric Field estimates level-2 in M-GSE coordinates

description: This data set contains spinfit DC Electric Field estimates in M-GSE coordinates that are measured by the Electric Field and Waves Suite (EFW) onboard Van Allen Probe A. One 2D vector estimate of the E-field is computed at a cadence of once per spin period (typically 10.7 to 11.1 s) using the survey E-field data product - the potential difference between EFW sensors V1 and V2 (E12) sampled at a nominal rate of 32 samp/s with a resolution of 16 bits. The X-component of the E-field estimate, corresponding to the axial component in the spacecraft coordinate system, is set to zero in this data product. See the EFW-FAQ (http://rbsp.space.umn.edu/efw_faq.html) for a discussion of this convention for this data product. The VxB electric field in the spacecraft frame due to orbital motion of the spacecraft around the Earth as computed from the spacecraft orbital velocity and measured B-field in the spacraft frame has been subtracted from the measured electric field, and so the data product is in the quasi-inertial frame equivalent to GSE (i.e. it is NOT in the corotation frame of the Earth!). Each spin fit is time-tagged with the time corresponding to the middle of the spin of data that went into the spin fit algorithm; in other words, if a given spin covers the interval (t1, t2), then the spin fit E-field estimate associated with that spin is given the time tag 0.5*(t1 + t2). The root mean square residual between the data included in the fit and the resulting best-fit model, sigma, and the final number of points included in the spin fit, npts, are also provided at spin-period cadence. The nominal dynamic range of the E-field estimate is +/- 1 V/m in any component.

title: Van Allen Probe A DC-coupled EFW 1-second sensor potentials relative to spacecraft in volts

description: This data set contains DC-coupled sensor potentials and negative of spacecraft potential relative to sensor floating potentials from the Electric Field and Waves Suite (EFW) onboard Van Allen Probe A. All six EFW sensor potentials are included. Also included are average potentials from opposing booms, i.e., (V1+V2)/2, (V3+V4)/2, and (V5+V6)/2, from autoscale and fixed scale (-15 to 5 V). These quantities are the negative of the spacecraft potential relative to the sensor floating potential, and have the contribution from the external electric field removed. Four spin-plane components of the electric field are measured at DC-12 Hz with 0.05 mV/m accuracy, and two spin-axis components, with ~3 mV/m accuracy. Spacecraft potentials cover cold plasma densities of 0.1 to ~100 cm-3 at 1-second cadence. The default sampling rate is 16 samp/s at 16-bit resolution, covering a +/- 225-V range. Further details on the EFW instrument in general or these data in particular can be found in the EFW Instrument paper, Wygant et al., 2013 (Space Science Reviews; submitted, 02/2013).

title: Van Allen Probe A Electric Fields and Waves (EFW) Level-3 Spin-fit Electric field in modified-GSE (MGSE) coord, density, and other products

description: This data set contains Level 3 wave electric field and search coil wave magnetic fields data from the Electric Field and Waves Suite (EFW) onboard Van Allen Probe A. The spin-fit electric field (spin period resolution) tends to be the most accurate electric field measurement. However, as always, due diligence by the user/scientists must be exercised in using these data. The spin-fit electric field is provided in both an inertial and co-rotating frame. The electric field is presented in a MGSE (modified GSE) coordinate system. We provide two components (Y MGSE and Z MGSE) of the electric field. Both components are in the spin plane of the spacecraft and are measured with the long 50 m booms. The X MGSE component is along the spin-axis. The spin-axis of the spacecraft is oriented within 37 degrees of the Earth sun line. So the Y GSE direction is most nearly aligned with the Y MGSE axis and the Z MGSE direction is most nearly aligned with Z GSE.
