4.0
Part of MAVEN Release 37. This release consists of a full redelivery
of SWEA data going back to 2014-11-15, and including the initial
release of 2023-11-15 to 2024-02-14. Here’s a list of improvements:
(1) Quality flag that identifies the sporadic low-energy anomaly.
Allows data filtering. Data will no longer masked. They will be
provided as is, along with a quality flag.
(2) Decrease deadtime from 2.8 to 1.0 microseconds, based on
in-flight calibrations. This fixes an over-correction of the data
at high fluxes that is present in previous versions.
(3) Updated sensitivity to account for SWIA recalibration.
(4) Secondary electron contamination is estimated for all three
data products. This allows much better estimates of flux, density
and kinetic temperature in the magnetosheath and for auroral
electrons.
(5) Better data sorting at day boundaries. SPEC data are bundled
into groups of 16 spectra and time tagged with the first spectrum
in the group. At a day boundary, some of the spectra in a bundle
belong with the current day and the rest belong with the next day.
The new version now properly sorts SPEC data at day boundaries.

a revised version of the data covered by the initial Release 28 (see Version
3.19). In the initial release, not all of the in-flight calibrations were
complete, and level 2 MAG data from 2021-10-01 through 2021-10-03 were not yet

28, including the initial release of the data covering 2021-08-15 to 2021-11-14.
Due to sporadic flagged in the data files in this release, a discussion of this
problem is provided in the Document Collection for this bundle. Good data in the
flagged band will be restored once the SWEA team develops an algorithm for
filtering data in the affected range. Note: After the initial release, there was
a release of a revised version of the data in this time range (see Version 3.20).

problem is provided in the Document Collection for this bundle. Good data in the
flagged band will be restored once the SWEA team develops an algorithm for
filtering data in the affected range.
2021-08-12

MAVEN Release 26. This version is an incremental release covering MAVEN Release
26, including the initial release of the data covering 2021-02-15 to 2021-05-14.

problem is provided in the Document Collection for this bundle. Good data in the
flagged band will be restored once the SWEA team develops an algorithm for
filtering data in the affected range.
2021-05-14

MAVEN Releases 25. This version is an incremental release covering MAVEN Releases
25, including the initial release of the data covering 2020-11-15 to 2021-02-14.

problem is provided in the Document Collection for this bundle. Good data in the
flagged band will be restored once the SWEA team develops an algorithm for
filtering data in the affected range.
2021-03-31

MAVEN Releases 21-24. This version is an incremental release covering MAVEN
Releases 21 -24, including the initial release of the data covering 2019-11-15
to 2020-11-14. Due to sporadic low energy suppression the energy band 3 - 25 eV
have been flagged in the data files in this release. A discussion of this
problem is provided in the Document Collection for this bundle. Good data in
the flagged band will be restored once the SWEA team develops an algorithm for
filtering data in the affected range.
