Data are available in HDF5 format on madrigal database, with web-based system to plot, download file, print file, and view file information. Each file contains data from one day of amateur radio signal report and the file contains twenty-four data parameters: year: Year (universal time), units: y month: Month (universal time), units: m day: Day (universal time), units: d hour: Hour (universal time), units: h min: Minute (universal time), units: m sec: Second (universal time), units: s recno: Logical Record Number, units: N/A kindat: Kind of data, units: N/A kinst: Instrument Code, units: N/A ut1_unix: Unix seconds (1/1/1970) at start, units: s ut2_unix: Unix seconds (1/1/1970) at end, units: s call_sign_tx: Transmitting station call sign, units: N/A txlat: Decimal latitude of sending station, units: deg txlon: Decimal longitude of sending station, units: deg call_sign_rx: Receiving station call sign, units: N/A rxlat: Decimal latitude of receiving station, units: deg rxlon: Decimal longitude of receiving station, units: deg tfreq: Transmitted frequency, units: Hz sn: Signal to noise ratio, units: N/A smode: Sender mode of operation, units: N/A ssrc: Sender source type, units: N/A pthlen: Signal path length (assuming shortest path), units: km latcen: Latitude of signal center point, units: deg loncen: Longitude of signal center point, units: deg NASA Enabling Space Weather Research with Global Scale Amateur Radio Datasets NASA 80NSSC21K1772 spase://SMWG/Person/Nathaniel.Frissell PrincipalInvestigator spase://SMWG/Person/William.Engelke TechnicalContact spase://SMWG/Person/Kornyanat.Hozumi MetadataContact spase://HamSCI/Repository/Madrigal Online Open https://cedar.openmadrigal.org/listExperiments?isGlobal=on&categories=4&instruments=8308&showDefault=on&start_date_0=1950-01-01&start_date_1=00%3A00%3A00&end_date_0=2025-12-31&end_date_1=23%3A59%3A59# Daily HamSCI Amateur Radio Signal Report on Madrigal database HDF5 Please acknowledge HamSCI team at The University of Scranton and The University of Alabama that collects amateur radio signal report from volunteers via three up-stream data providers including WSPRNet, PSKReporter, and Reverse Beacon Network. The data are available to public at MIT Madrigal database. This effort is supported by NASA grant number 80NSSC21K1772.
