2.3.1 spase://CNES/NumericalData/CDPP-AMDA/MESSENGER/FIPS/mess-fips-ntp ntp Ion Moments 2017-01-16T14:08:29Z This data set contains FIPS ( FIPS_NTP) ion number densities and temperatures, as well as the pressure calculated from their product. Quantities are calculated after sufficient time accumulation to allow meaningful interpretation. In this version of the dataset, many of these products are provided in regions determined by hand-picked or modeled bow shock and magnetopause boundaries. Boundary picking was done by the MAG team at a level of accuracy sufficient for the relatively low time resolution FIPS data (10s - 60s). Where these were not available, the model given by Slavin et al. [Science, 2010] is used. spase://CNES/Person/George.Ho DataProducer EPPS PDS products https://pds-ppi.igpp.ucla.edu/data/MESS-E_V_H_SW-EPPS-3-FIPS-DDR-V2.0/DOCUMENT/DDR_SIS/EPPS_DDR_SIS.HTM spase://CDPP/Repository/AMDA Online Open http://amda.cdpp.eu NetCDF PDS Calibrated MESS-E_V_H_SW-EPPS-3-FIPS-DDR-V2.0/FIPS_NTP spase://CNES/Instrument/CDPP-AMDA/MESSENGER/FIPS IonComposition 2008-08-20T16:03:35Z 2015-04-30T15:08:18Z PT60S Mercury The recovered density, temperature and pressure (NTP) product is particularly sensitive to the region of Mercury's space environment in which the data was taken. The reasons for this, based on validity of required assumptions, are described in detail in the DDR SIS. This data is provided within the magnetosphere, where the assumptions are likely to hold for averages of 1 minute or more. It is also provided in the magnetosheath within a 45 degree cone angle of the X_MSO axis. The validity of the assumptions is much more variable here, though they will often hold. USERS ARE STRONGLY CAUTIONED to read the NTP section of the DDR SIS follow the recommendations for using these quantities.
