Imaging Riometer for Ionospheric Study Data
Listed in NASA Earthdata CMR
The Imaging Riometer installed at Zhongshan Station is one of the cooperative projects between the Polar Research Institute of China (PRIC) and Japan's National Institute of Polar Research (NIPR).
Description
The Imaging Riometer's antenna array consists of 8*8 dipole-elements with a half-wavelength spacing at 38.2MHz. It can monitor energy particle precipitation by observing cosmic noise absorption all day, with a 400*400 km view field and 20km resolution over Zhongshan Station at 90km altitude.
The observation has been ongoing since February 1997. Because of the digisonde noise, the quality of the data during 1997 is not good.
