Digisonde Portable Sounder 4 data on the Zhongshan station, Antarctica, Year 1995
Listed in NASA Earthdata CMR
The DPS-4, developed by the University of Masachusetts at Lowell Center for Atmospheric Research (ULCAR), is a pulse HF Doppler radar controlled by a computer.
Description
It can measure the amplitude, phase, time delay, frequency, Doppler shifts, and angle of arrival and wave polarization from ionospheric echoes. The data is stored originally in a quarter-inch cartridage and retrieved by the Library software and saved on CDR disks eventually.
