MESSENGER: GRS Derived
Analysis Products
The MESSENGER GRS Derived Analysis Products (DAPs) are maps of gamma-ray
count rates or
elemental abundances derived from summed GRS data, each with
a corresponding one standard deviation error map.
See Peplowski, P.N., et al., Variations in the
abundances of potassium and thorium on the surface of
Mercury: Results from the MESSENGER Gamma-Ray
Spectrometer, Journal of Geophysical Research, 117,
E00L04, doi:10.1029/2012JE004141, 2012.
The GRS DAPs are stored along with the
GRS Calibrated Data Records (CDRs) and
Reduced Data Records (RDRs) on PDS volume
MESSGRS_2001. Please see below for direct
access to the volume. Only
directories pertaining to the DAPs are
listed below.
Alternatively, to search the archive for
data that meet particular criteria, e.g.
time and location, use the
Mercury Orbital Data Explorer (ODE).
