Digital Ionospheric Sounding Measurements in Greenland
Abstract
The three digisondes located at the Greenland west coast sites, Narsarsuaq, Kangerlussuaq and Qaanaaq, have been operated according to the EOARD agreement. The acquired data were processed on site and stored as a sequence of one-day files on CD-ROM. The data were delivered via electronic communication links (intemet connections) to AFRL. Backup copies of the data (CD-ROMs) were shipped to DMI where an archive of the records is kept. A few small upgrades and replacements of minor components with spare parts received from AFRL resp. its subcontractor were performed. Otherwise the instruments were operated under routine supervision and with routine maintenance by on-site personnel. No substantial technical problems which would have resulted in loss or non-usability of recorded data were reported. Verification of data quality and accuracy is ongoing. Comparison of plasma density profiles obtained with the digisonde and the incoherent scatter radar, colocated at the Sondrestrom Upper Atmosphere Research Facility, has shown good agreement between coincident data sets from the two different sensors.
