UARS Particle Environment Monitor (PEM) Level 3TP V004 (UARPE3TP) at GES DISC

Version 004 eng
  • Abstract
    The Particle Environment Monitor (PEM) Level 3TP data product consists of daily, 65.536 second and 2.048 interval time-ordered, vertical profiles of electron and proton rates. PEM was made up of four instruments: the Atmospheric X-Ray Imaging Spectrometer (AXIS), the High Energy Particle Spectrometer (HEPS), the Medium Energy Spectrometer (MEPS), and the Vector Magnetometer (VMAG). PEM was flown on NASA's Upper Atmosphere Research Satellite (UARS) to measure the type, amount, energy, and distribution of charged particles injected into the Earth's thermosphere, mesosphere, and stratosphere. The PEM Level 3TP data are processed with the version 4 algorithm.The PEM level 3TP data are a special data product, providing higher temporal resolution than the level 3AT data, with the HEPS and MEPS instrument data in separate files. The HEPS profiles are made every 65.536 seconds, and the MEPS profiles are made every 2.048 seconds. The PEM level 3TP data consist of 4 granules per day: 1. HEPS_ELEC_ED - HEPS electron energy deposition 2. HEPS_PROT_ED - HEPS proton energy deposition 3. MEPS_ELEC_ED - MEPS electron energy deposition 4. MEPS_PROT_ED - MEPS proton energy deposition The units for energy deposition rate are in [erg/cm**3/sec]. The PEM data are on the UARS standard altitude levels (in km) given by: z(i) = 5 * i, i <= 12 z(i) = 60 + (i - 12) * 3, 13 <= i <= 32 z(i) = 120 + (i - 32) * 10, 33 <= i <= 50The data files are available in a binary record oriented format.
