The SREMSpace Radiation Environment Monitor data files contain calibrated data for the different energy and particle species channels available in the SREMSpace Radiation Environment Monitor. Each data file contains 24 hours of data - from midnight to midnight UTCUniversal Time Coordinate(d). (note this is not an Operational Day) - with the date covered by the file easily identifiable through the file name.
SREMSpace Radiation Environment Monitor calibrated data was produced from the SREMSpace Radiation Environment Monitor raw data acquired during the entire mission.
Data for the SREMSpace Radiation Environment Monitor on board other ESAEuropean Space Agency missions can be retrieved from the Paul Scherrer Institute . In order to retrieve the data you will need to register first.
The files containing the SREMSpace Radiation Environment Monitor calibrated data will have a name of the form SREMPlanck_PACC_YYYYMMDD.fits where PACC stands for Processed ACCumulated data and YYYYMMDD is the date the data in the file was acquired.
The SREMSpace Radiation Environment Monitor processed data can be downloaded from the PLAPlanck Legacy Archive interface: "Ancillary data" tab of the "Time-ordered information" section.
A list of the files available can be found here.
Each file contains three binary table extensions named CDFFITS1,CDFFITS2 and CDFFITS3. The first extension contains the accumulated counts data, the second extension the labels to identify the data in the first extension and the third extension the total radiation dosis. The contents of each extension are as follows.
|EPOCH||vector containing 1 string with UTCUniversal Time Coordinate(d) for center of accumulation interval in ISO format (YYYY-MM-DDTHH:MM:SS.MMMZ)||A24||NA|
