POSTVIEW DATA FIELD PSP
PSP/FIELDS data release 5.1 (2020 October 19) updates two data products, the DFB survey waveform differential voltage and the DFB burst waveform SCM files, to Version 3.Burst data from Encounter 4 will be included in the next release. Survey data from 2020 January 15–2020 April 30 is included. PSP/FIELDS data release 5 (2020 September 15) includes data from the fourth PSP encounter in January 2020.PSP/FIELDS data release 4 (2020 August 4) includes data from the first two PSP Venus flybys, TDS waveform data from the first three encounters, and merged search coil and fluxgate magnetometer data from solar encounter 1.PSP/FIELDS data release 3 (2020 April 14) includes survey data through 2020 January 14, and select data from solar encounter 3.PSP/FIELDS data release 2 (2020 February 10) includes survey data from PSP Encounter 3, and select data (DFB burst waveforms and cross spectra) from solar encounters 1 and 2.The initial data release on 2019 November 12 includes survey data from the first two PSP solar encounters, which had their perihelions on 2018 November April 4, respectively.Therefore, a typical release of PSP/FIELDS data may include survey data from the previous Encounter N, and burst data from Encounter N-1. The time required for selection and transfer can lead to a substantial delay between the downlink of survey data and burst data products. After this selection, the burst data is transferred from the FIELDS SSR to the spacecraft SSR, and transmitted at the next available set of contacts.
Specific intervals of this “burst data” are selected for downlink after the encounter. These include high time cadence “burst” waveforms from the TDS and DFB (see below), as well as cross spectral data from the DFB.
Other data products are recorded to the FIELDS internal SSR. Survey data products are often transmitted to the ground shortly after encounter, although this is not true for all encounters. These “survey data” products include waveform data from the magnetometers and electric field antennas, and spectral data from the DFB and RFS instruments (see below). Survey and burst dataĬertain FIELDS data products are recorded directly to the spacecraft solid state recorder (SSR) during the encounter. All interested users should read the Rules of the Road for use of FIELDS data. FIELDS data products are available in NASA CDF format. All PSP/FIELDS Level 2 and higher data are open to all scientists and the general public.
