MESSENGER E/V/H MASCS 4 UVVS DERIVED DATA V1.0

Published by National Aeronautics and Space Administration | National Aeronautics and Space Administration | Metadata Last Checked: July 18, 2025 | Last Modified: 2025-07-17
Abstract ======== This data set consists of the MESSENGER MASCS UVVS derived data records, also known as DDRs. There are three types of UVVS DDRs: surface, atmosphere, and atmospheric model. There are two surface DDR data products associated with each UVVS observation set: a science header table and a science data table. There are nine geometry-classified atmosphere DDR data products, consisting of three different observation types for each of sodium (Na), calcium (Ca), and magnesium (Mg). There are three orbit-level summary atmosphere DDR data products, one each for Na, Ca, and Mg. There are 3 atmospheric model data products, one each for observations of Na, Ca, and Mg.
