Abstract:
Ionospheric Total Electron Content (TEC) is the total number of electrons in a column of unit cross section extending from the transmitter to receiver. TEC is calculated from observations of the rotation of a polarized signal (Faraday rotations) transmitted from the satellite. Most of the TEC data have had limited quality control work done and are considered "raw" data. USAF Global Weather Central (GWC) has supplied data from January 1980 through May 1992. During this period, there have been a many as twelve and as few as ten recording stations. The stations are Anchorage (61.2N,210.1E), Athens (38.0N,23.60E), Boulder(40.0N,254.7E), Goose Bay (53.3N,299.2E), La Posta (32.8N,243.5E), Lunping (24.9N,121.2E), Osan (37.2N,127.1E), Palehua (20.7N,203.7E), Patrick (28.2N,279.4E), Ramey (18.1N,293.8E), Sagamore Hill (42.6N,289.2E), and Shemya (52.7N,174.1E). There is a limited amount of TEC data available from Sagamore Hill and Sydney (34.0S,150.7E) from 1967 - 1974. The data consist of hourly values, medians, and median counts. Data are available on magnetic tape or IBM-compatible diskette. The smallest division of data that will be pulled for a data request is a network month. Each month has from one to twelve stations for each network month. For GWC data, there will be at least ten to twelve stations for each month.
Purpose:
Ionospheric Research
Supplemental_Information:
Observing station type: Solar-Terrestrial Observatory, Satellite. Number of sites: 12 observatories. Quality control: Accuracy of data range from 2 percent to 30 percent,depending on the technique used for calculations and the validity of assumptions for the particular observational condition.
