| GOES-R Series Level 1b SEISS Energetic Heavy Ion Sensor (EHIS) Product in Daily Aggregations |
 |
The Energetic Heavy Ions product contains heavy ion directional differential flux
values measured in situ in geostationary orbit. The differential flux values are produced
for the Hydrogen (H), Helium (He), Carbon-Nitrogen-Oxygen (CNO), Neon-Sulfur (Ne-S),
and Chlorine-Nickel (Cl-Ni) mass groups, and for individual elements between Beryllium
and Copper (Be-Cu). The product includes data quality information that provides an
assessment of the differential flux values, including whether they are invalid, and
an indication of good or degraded quality. The rationale for the quality assessment
is also given. (See the README file for additional quality assessments.) For each
mass group, heavy ion flux is reported in five energy bands for one angular zone.
Similarly, for each element in the elemental group, heavy ion flux is reported in
five energy bands for one angular zone. The five energy bands are evenly spaced logarithmically
spanning from 10 to 200 MeV per nucleon for the H and He mass groups. For all the
mass groups and the elemental group, the energy band bounds are dynamic and included
in the product. The one angular zone has a central look-angle that is anti-earthward
and has a 60 degree conical field of view. The units of measure for the directional
differential flux values are particles per second per square centimeter per steradian
per (megaelectron volt per nucleon). The Level 1b product has a 5-minute cadence,
corresponding to an accumulation of counts over a 5-minute period. |
