Statistical analysis of midlatitude spread F using multi-station digisonde observations

Journal of Atmospheric and Solar-Terrestrial Physics, 2018
Abstract A comprehensive statistical study of midlatitude spread F (MSF) is presented for five midlatitude stations in the North American sector. These stations include Ramey AFB, Puerto Rico (18.5°N, 67.1°W, −14° declination angle), Wallops Island, Virginia (37.95°N, 75.5°W, −11° declination angle), Dyess, Texas (32.4°N, 99.8°W, 6.9° declination ...

Differences between GPS and digisonde measurements of Total Electron Content at Tucumán

Acta Geodaetica et Geophysica Hungarica, 2010
Measurements of Total Electron Content (TEC) were obtained from GPS and digisonde data, at Tucuman (26.69°S, 65.23°W), for days in different seasons, and with different geomagnetic activities, in 2004. Differences between both methods — associated with plasmaspheric content — are analyzed regarding hourly behavior, magnetic activity, and season; and ...

Automatic Scaling of Digisonde Ionograms Computer Program and Numerical Analysis Documentation,

1983
Abstract : Automatic scaling of Digisonde ionograms by the ARTIST system is discussed and reference is made to the ARTIST's success in scaling over 8000 ionograms. Some of the numerical methods implemented by the ARTIST system are described in detail and the logic of the ARTIST software is explained.

DINData: A Windows Software to Reformat and Clean Digisonde Numeric Dataset

The ionospheric numerical ionogram dataset in the Digisonde Ionogram Database (DIDBase), hosted by the Global Ionospheric Radio Observatory (GIRO), provides an important opportunity to study the bottomside ionospheric electron density profile. However, this dataset often contains inconsistencies, including missing observation periods, irregular time ...
