Thread: Information request about PAS/CI pressure sensor

Dear IRIS Team,




I hope this email finds you well. I am writing to request information about PAS/CI pressure sensor.




I'm a Ph.D. student in Solid Earth Geophysics at Chinese Academy of Sciences. I have noticed that there are several types of barometric sensors, including Setra-278, Paroscientific Microbarograph, CI/PAS pressure sensor, etc., installed in GSN stations. It's strange to me that there is little information about the CI/PAS sensor on the Internet. However, many GSN stations are currently using it (e.g. station ANMO in network IU, IRIS: MDA : IU : ANMO : 31 : LDO).




I would be grateful if you could provide me with this information (e.g. pressure range, accuracy and resolution), as well as any additional resources that you have available (such as data sheets, user manuals, or technical specifications).




Thank you very much for your attention to this request. I look forward to hearing back from you.




Best regards,

ZhangGeng
