ResourceID spase://NASA/NumericalData/RBSP/A/EFW/L2/SPEC/PT4S 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.

Description SCM perpendicular-2 Caveats 112 bin spectrogram for SCMperp2 Structure Size 112 Mixed MixedQuantity Other Parameter #83 Name Time, UTC ParameterKey epoch_qual Description Timetags for elements of efw_qual Caveats The elements of efw_qual are determined on a fixed cadence regardless of the nominal cadence of the individual L2 data products, and epoch_qual provides storage for those fixed-cadence time tags.. Units ps Mixed MixedQuantity Other Parameter #84 Name EFW Data Quality Flags ParameterKey efw_qual Description An array that indicates a global estimate of EFW data quality, as well as a breakdown of observatory and instrument-level data quality issues that impact the global quality estimate.. Caveats The quality of EFW data products can be affected by a variety of observatory and instrument-level conditions. efw_qual is a collection of flags that show the estimate of each of these contributors over time. ..See the EFW-FAQ (http://rbsp.space.umn.edu/efw_faq.html) for a detailed description of the determination and meaning of each of the elements of efw_qual. If the value of a particular element of efw_qual is not relevant to the quality of a particular data product, it shall receive the value EFW_QUAL_NR (typ. -2). If the value of a particular element of efw_qual is relevant to the quality of a particular data product but is not known at the time lf L2 data production, it shall receive the value EFW_QUAL_UNK (typ. -1). A quality value of EFW_QUAL_GOOD (typ. 0) indicates that there are no known issues with the data product due to that particular element of efw_qual. The quality values are meant to be conservative, and values other than EFW_QUAL_GOOD should lead the user back to a member of the EFW instrument team for discussion and advice on the nature of the data quality as needed.
