The millimeter wave radio astronomy database (http://www.radioast.csdb.cn/)  was  built by Purple Mountain Observatory (PMO), Chinese Academy of  Sciences (CAS), and has recently been put into trial operation. 13.7 m  telescope was the only equipment in China, operating at millimeter  wavelengths. So far, astronomers from the United States, Japan, Germany,  Britain, Russia, China and other countries, using the 13.7 m telescope  have carried out a series of research on the solar system, interstellar  gas, and nearby galaxies, and have made many contributions to scientific  progress.

The database  was built to meet the demands of data storage of the newly  developed Superconducting Spectroscopic Array Receiver (SSAR) and  on-the-fly observing technique. Currently, the database contains all  data taken since 2003. The data taken between 2003 and 2009 include  about 1.18 million spectra, which are all publicly available now. At  present, we are creating user logins for all PIs of currently running  projects, which will allow them to access their data easily. After a  proprietary period of one year, the data will be made publicly available  at the website.　 

The millimeter  wave radio astronomy database is a subproject of Scientific database,  CAS. This project received lots of assistances from Computer Network  Information Center and other members of Scientific database, CAS.

If you have an  inexplicable problem retrieving your proprietary data, please contact  us. Your feedback will also help inform our future planning for  improvements to our level of service and support.
