The Spectral Data at Waveband 4.50–7.50GHz of Solar Radio Spectrometer of the Purple Mountain Observatory

The sun is the nearest star from earth. Observation and studies of the sun has been an important part of the basic astronomic research all the time. Observation found that the sun is a celestial body which has its own atmosphere, which is almost entirely ionized to plasma due to high temperature. Together with changes of its own magnetic fields result in complex and spontaneous solar activities. Observation and research of solar eruptions and understanding of its physical process are frontiers of solar physical study. Solar radio spectrometer is able to carry out multi-channel simultaneous observation at a wide bandwidth. The spectral data from 1998 to the present has been observed and stored. The bandwidth of data is 4.5-7.5GHz.The frequency resolution of data is 10MHz, so there are 300 channels. Its time resolution is 5ms.Since the observation began, we have stored spectrum data of more the 200 solar flares.
