Abstract
The Energetic Particle Detector (EPD) onboard Solar Orbiter is a suite
of multiple sensors (Suprathermal Electrons Protons, STEP; Suprathermal
Ion Spectrograph, SIS; Electron Proton Telescope, EPT; High Energy
Telescope, HET), which measures particle intensities over a wide range
of energies (from suprathermal to relativistic energies) and for
different species (electron, protons, and heavy ions) in different
directions. The EPD data center (http://espada.uah.es/epd) offers a
primer venue to inspect the Solar Energetic Particle (SEP) activity,
both to promptly check the most recent solar activity using quicklook
plots based on low-latency data sets, and to perform deeper studies with
data validated for scientific use. Among others, a series of plots and
relevant information, such as the spacecraft maneuvers or sensor
updates, are provided to the community. This facility gives access to
all the data from the EPD sensors (which can be also found in the Solar
Orbiter Archive), including Level 2 (calibrated) as well as more
elaborated Level 3 data in the near future, which have further
processing. An application programming interface (API) is also offered
for accessing EPD data. Besides, during the first year and a half of
observations, Solar Orbiter has completed three orbits, and EPD has
measured several increases in particle fluxes, due to heliospheric and
solar-origin events. Some of the events have been analysed and the flux
enhancements have been tagged for future studies. This work aims to let
the community know the availability of the instrument data products, and
to explain how to properly use the provided data products and plots, as
well as to summarise all the available studies published until now.
