Material presented is a Supplement to a manuscript sent for consideration of publication to Journal CIEES. It comprises a data set created using GPS-based estimated values of Total Electron Content (TEC) and dTEC, as well as observations of components of geomagnetic field density around the city of Darwin, NT, Australia during 2014. 

TEC & dTEC are estimated from raw GPS pseudorange observations collected from the open access internet-based NASA IGS Data repository (https://www.earthdata.nasa.gov/), and processed using the GPS-TEC programme developed by Dr Gopi Seemala (https://seemala.blogspot.com/). 

Geomagnetic field density components Bx, By, Bz are taken from the open access internet-based repository INTERMAGNET (https://www.intermagnet.org/data-donnee/download-eng.php).

Data from two sources are collected, aggregated, collated, and structured in a form of machine-readable CSV format to serve as an open source database for research on geomagnetic effects on TEC and GPS/GNSS ionospheric delay conditions. Database creation is performed using bespoke programme developed by author RF in the R environment for statistical computing (https://www.r-project.org/).
