Mars Atmosphere and Volatile EvolutioN (MAVEN)
Extreme Ultraviolet Monitor (EUV)
Modelled PDS Archive Bundle
LID = urn:nasa:pds:maven.euv.modelled
Bundle Description
==================
Overview
--------
This bundle contains solar irradiance spectra in 1-nm bins from 0-190 nm. The
spectra are generated based upon the Flare Irradiance Spectra Model - Mars
(FISM-M) using the EUV calibrated band irrandiance and interpolated
Earth-based solar indices and measurements as proxies.

Version Date Description
------- ------------ ---------------------------------------------------
1.0 2016-05-20 Intitial release (including the same coverage as
MAVEN Releases 1-5).
2.0 2016-08-15 MAVEN Release 6 (2016-08-15): This version includes
a full redelivery of the MAVEN EUV modelled data
bundle. In this version the data files include an
additional field indicating the Sun to MAVEN
distance.
3.0 2016-11-15 MAVEN Release 7 (2016-11-15): This version includes
a full redelivery of the MAVEN EUV modelled data
bundle. In this version the data files include an
additional field indicating the Sun to MAVEN
distance.
4.0 2017-02-17 MAVEN Release 8 (2017-02-15): This version includes
a full redelivery of the MAVEN EUV modelled data
bundle. In this version changes were made to the
calbration used on the calibrated upon which these
data based.
5.0 2017-05-12 MAVEN Release 9 (2017-05-15): These data have been
regenerated to correct a CDF leap second issue that
appeared in the 2017 data, and to fix a small error
in the model that was causing occasional, small
steps in the data. This release includes a full
redelivery of data from 2014-10-18 to 2016-11-14 and
the initial delivery of 2016-11-15 to 2017-02-14.
6.0 2017-08-16 MAVEN Release 10 (2017-08-15): This version includes
a full redelivery of the MAVEN EUV modelled data
bundle, including the initial release of 2017-02-15
to 2017-05-14. These data were regenerated to correct
the SPICE kernel information.
7.0 2017-11-17 MAVEN Release 11. This release consists of the initial
release of the daily data for 2017-05-15 to 2017-08-14,
plus the re-release of all all of the previously released
daily data. These data have be processed using new
field-of-view, temperature-gain, and degradation
corrections. The new FOV correction is based on a new
technique of using all off-points in addition to the
planned FOV map maneuvers to determine the FOV variability.
This has allowed the expansion of the useable pointing
range so that some data formerly flagged as "bad" for
pointing reasons are now flagged as "good" data. The
temperature-gain and degradation correction updates are
improved fits to the calibration changes tracked throughout
the mission.
8.0 2018-02-20 MAVEN Release 12 (2017-02-15). This version includes
a full redelivery of the MAVEN EUV modelled data
bundle, including the initial release of 2017-08-15
to 2017-11-14.
9.0 2018-05-16 MAVEN Release 13 (2018-05-15). This release consists of the
initial release of the data covering 2017-11-15 to 2018-02-14,
plus the re-release of all of the previously released data.
Total coverage is 2014-10-19 to 2018-02-14. This version of
the data data (rev 02, ver 11 data files), correct an error in
the flags. In the previous revision data during rapid slews of
the spacecraft were incorrectly labelled as "good solar data"
resulting in large spikes in the data during those slews. A
rate of slew limit has been incorporated in the flag criteria,
correcting the problem. In addition, a citation to the paper
describing the EUV spectral model has been included in the CDF
attributes and PDS label Reference_List.
10.0 2018-08-13 MAVEN Release 14 (2018-08-15). This version includes

a full redelivery of the MAVEN EUV modelled data
bundle, including the initial release of 2018-05-15
to 2018-08-14. These data have been generated using the most
recent calibration.
11.1 2019-02-15 MAVEN Release 16 (2019-02-15): This version is an incremental
release of the MAVEN EUV modelled data bundle, including
the inital release of the data covering 2018-08-15 through
2018-11-14. This version also includes updates to the label
file contents, and a revised version of the SIS.

of the MAVEN EUV modelled data bundle, including the inital
release of the data covering 2018-11-15 through 2019-05-14.
The modelled daily and minute products have undergone updates
in the processing pipeline and in the model coefficients
resulting in improved production efficiency and model uncertainty.
Some of the irradiances have changed considerably from previous
versions, rendering the older versions obsolete. The minute
products have also been re-tuned to use other proxies when the EUV
Channel B (0-7 nm) irradiances are not available after the anomaly
in that channel. Note that the L3 daily product model does not use
the Channel B irradiances as a proxy, only the minute product
model does.
