This page provides information about RPW public data releases.
About RPW data release philosophy
RPW public data are released by LESIA on daily basis. Only L0/L1/L2 data older than 90 days are freely accessible. If a public data file needs to be re-processed, the new version is made available within 48 hours following its generation.
The release notes below gives the history of the RPW public data, which have been re-processed during the mission (i.e., except for the first delivery on September 2020, "release" and "re-processing" terms are equivalent in these notes).
Only main changes relevant for the science community are reported in the tables for each products. For a detailed modification history, including technical updates, please read the software changelog in ROC gitlab site (restricted access).
N.B. Official data providers (LESIA, ESAC, NASA, CDPP) will always supply as a first choice the latest version of the RPW data products.
