Low altitude NOAA/POES satellites have measured energetic particles with MEPED instrument from 1979 to present. However, these measurements have suffered from a variety of instrumental and data quality problems, but recent advances in detailed understanding of the MEPED instrument have allowed us to calibrate and correct the data. Currently, this database forms the longest systematically calibrated energetic particle dataset in space physics. It has now been made available though the ESPAS Data Portal in 1/4 satellite orbit time resolution. The offered data products include average energetic proton and electron fluxes in two directional telescopes at different energy channels from two opposite local time sectors and hemispheres. The data allow one to study the particle fluxes in a variety of time scales from space weather events to space climate time scales over several solar cycles. Here we review the work done to correct and recalibrate the MEPED database and describe in detail the data products published in ESPAS Data Portal.
