Database produced for and associated with journal article https://doi.org/10.1029/2021RS007328 This database contains scintillation events identified by the "Detect, Classify, Hypothesize" method as described in the journal article. Created by Datta-Barua, Seebany. Open Access License Creative Commons Attribution 4.0 International Sheets labeled "S*_yyyy_freq" contain a list of scintillation events based on data from the SAGA array. For S* the abbreviations are: "SP": sigma phi index, i.e., phase scintillation events "S4": S4 index, i.e., amplitude scintillation events "SPS4": sigma phi and S4, i.e., both-phase-and-amplitude events yyyy indicates the four-digit year, from 2014 through 2019 freq: "L1CA": refers to GPS L1 frequency 1575 MHz "L2CL": refers to GPS L2C frequency 1227 MHz In each sheet "S*_yyyy_freq" the columns are: Column A: Year (2014-2019) Column B: day of year (1-366) Column C: frequency (1 for L1, 2 for L2C) Column D: GPS satellite PRN (1-32) Column E: Scintillation start UT hour (0-23) Column F: Scintillation start UT minute (0-59) Column G: Scintillation end UT hour (0-23) Column H: Scintillation end UT minute (0-59) Column I: number of receivers operational (4-6) Column J: PFISR-based hypothesized layer (1-7, as described below) 1: E layer (majority peak height < 150 km) 2: F layer (majority peak height > 195 km) 3: T layer (150 < majority peak height < 195 km) 4: I layer (no majority layer) 5: "N"- no Poker Flat Incoherent Scatter Radar (PFISR) long pulse data and no alternating code data 6: "NLP" - no PFISR long pulse 7: "NAC" - no PFISR alternating code A blank sheet indicates that there were no events of that type and at that frequency found in that year.
