1 2 Outline Status of data sharing Visions on data and products service

Status of Data sharing 1 Marine meteorological, wave, sea surface temperature and salinity data from 13 China oceanographic stations : Xiaochangshan, Dalian, Yantai, Xiaomaidao, Lianyungang, Lvsi, Shengshan, Zhenhai, Dachen, Nanji，Beishuang, Dongshan, and Zhelang. Sea surface temperature and salinity, and marine meteorology data （air temperature, air pressure, humidity and wind） Data interval：hourly Temporal coverage ：January 2010 to now Updating frequency：every month Wave data Data interval：4 times/day（8:00, 11:00, 14:00, 17:00） Temporal coverage ：January 2010 to now Updating frequency：every month

Status of Data sharing 1 Monthly Mean Sea Level Delayed Mode Data  from 6 China oceanographic stations : Dalian, Lvsi, kanmen, Zhapo, Nansha, and Xisha. Monthly mean sea level Temporal coverage : January 1996 to now Updating frequency: every month Delayed Mode Temperature and Salinity Data  from 4 China oceanographic stations : Shidao, Xiaomaidao, Lianyungang and Yinshuichuan. Delayed mode sea surface temperature and salinity Temporal coverage : January 1996 to now Updating frequency: every month

Status of Data sharing 1 Wave Data  from 4 China oceanographic stations : Shidao, Xiaomaidao, Lianyungang and Yinshuichuan. Wave data (wave direction and speed) Data interval：4 times/day（8:00, 11:00, 14:00, 17:00） Temporal coverage：January 1996 to now Updating frequency：every month

Status of Data sharing 1 Metadata information of the China oceanographic stations What is being observed?---parameters How ? ----instrument, frequency What had been done before data are publicly available?—QC? Quality assurance ? Who manage the data ? … Laohutan Marine Environment Monitoring Station

Status of Data sharing 1 Metadata of China oceanographic station observation Basic info of oceanographic stations Observation parameters Observation instruments Basic info of tide gauge Tide gauge benchmark Measurement records of tide gauge benchmark GNSS(GPS) observation information Tide gauge well and land subsidence information of adjacent areas Missing data of tide and reasons Environment info of wave observation Environment info of sea temperature and salinity observation Environment info of marine meteorological observation Missing data of wave and reasons Missing data of temperature and salinity and reasons Missing data of meteorology and reasons
