Data recorded by the WISPR instrument during the first two solar encounters by Parker Solar Probe (PSP) were publicly released as of November 12, 2019. Data for the third (September 2019) encounter will be available early 2020. For future encounters, the data are to be made public at most three months from the date that all telemetry from that encounter has been received on the ground. 

Available Data and Data Types

Data is currently available for:

  • Encounter 1 (10-31-2018 - 11-11-2018)
  • Encounter 2 (03-30-2019 - 04-10-2019)

We are making several data products available including raw and processed images (science data and PNGs), and movies (animations) in different formats. The science data is provided in the FITS (Flexible Image Transport System), for which three different products are available: Level-1, Level-2 and Level-3, described below.

  • Level-1 (L1): de-compressed, uncalibrated image data with no correction applied, except for rectification, so that solar north is (approximately) up. Data units are DN.
  • Level-2 (L2): calibrated data in units of Mean Solar Brightness (MSB), with bias, stray light and vignetting corrections applied.
  • High-cadence L2: approximately half of WISPRs observations are high-cadence narrow field of view observations, designed for the high temporal resolution studies of solar outflow. These data are separated from the full-field science data as they are fundamentally different types of observation.
  • Level-3 (L3): data designed to reveal the variations in solar K-corona via a subtraction of a "background" model (L2b data; see below) that primarily removes the dominant F-coronal signal. These data are usually in units of MSB, though this should be verified by inspection of the FITS headers. We do not provide L3 data for the high-cadence observations.
  • Level-2b (L2b): Generating appropriate background models for use with WISPR observations is complex, requiring at the very minimum the consideration of an entire encounter of observations as well as numerous corrections for instrumental effects, distance from the Sun, and other observing parameters. We are making these background models available as a Level-2b (L2b) data product. We do not provide backgrounds for the high-cadence data.
  • Summary: Plain ASCII text files that summarize the observations of each type recorded during each encounter.
  • PNGs: Browse images created using the L3 data product. These data are separated by encounter and by camera ("inner" and "outer")
  • MPGs and MVIs: movies in the MPEG and IDL/SolarSoft mvi formats.

Choosing your data product

In most circumstances, we recommend use of the Level-2 or Level-3 data products for essentially all scientific analyses, both qualitative and quantitative. The PNG and various movie formats are appropriate for browsing the data but should not be used as science products.

Data Access

The WISPR FITS science data can be accessed from our Database Query Form or via direct https links to the individual files. All other data products must be accessed directly from the following links. For convenience, we are also providing zip files of each data product for each encounter for those that would like to download all observations. Please note that the L3 data starts on Nov 01 2018 for Encounter 1, and April 01 2019 for Encounter 2.

While utilities like wget should work for retrieving data from the provided direct links, we recommend the use of our WISPR Database Query Form for retrieving individual file. Alternatively, for downloading of entire sets of data, we currently provide the below zip files. These zip files collectively contain all WISPR science data recorded during the encounters listed. Unless specified, the files contain data for both inner and outer cameras. The summary files, which contain the primary metadata for the observations, are also provided.

Important Note About WISPR Data Versions

As noted, processing and calibration of WISPR observations is extremely challenging. Accordingly, while we do not anticipate significant changes to the data, there may in the future be changes made to the L2 and L3 data products as our understanding of the observations and instrument behavior evolves, and as we receive more telemetry from future encounters. Thus, each .fits filename contains a version identifier (e.g. "V1" in file "psp_L3_wispr_20190404T053701_V1_1221.fits") identifying the release version. Currently all data are Version 1 (V1). We will make a note on this page of any changes to the WISPR data versions.
