"With the rapid development of China's marine economy, China's marine equipment is changing with each passing day. For example, just last month, the large marine observation buoy we developed was successfully deployed in the Arctic Circle Norwegian waters along with the'Snow Dragon' scientific research ship. This is the first time that large buoys have been used to monitor the marine environment in this area." When the reporter interviewed the Institute of Marine Instrumentation of the Shandong Academy of Sciences, Liu Mengde, director of the institute and vice president of the Shandong Academy of Sciences, said, "Not only that, we developed New marine equipment such as atmospheric aerosol lidar and volunteer ship automatic forecasters have also reached the international advanced level."
Recently, the dispute over the sovereignty of the islands around our country has been staged one after another, and the people's awareness of the importance of the ocean has also increased unprecedentedly. Liu Mengde said that the 21st century is the century of the ocean, and the ocean economy has great potential, and it has increasingly become an important growth point for the development of a country or a region; new marine equipment will provide strong industrial support for promoting the construction of my country's marine economy and safeguarding marine rights and interests. The new buoy "test water" in the Arctic Circle Liu Mengde said that unlike the marine buoys deployed in the near sea, the "sea-air coupled observation buoy" deployed in the Norwegian Sea not only has a larger "block", but also has a qualitative technical content. Promote. The buoy has a diameter of 6 meters, a height of 15 meters, and a weight of about 15 tons. It can observe atmospheric boundary layer data, upper and deep ocean structure changes, and obtain real-time sea-air heat flux, ocean convective mixing, and sea-air carbon dioxide flux in the sea area. 1. The material flux from the ocean to the atmosphere to quantitatively observe the seasonal and interannual changes of the air-sea coupling in the sea area. It is particularly worth mentioning that the buoy uses a sensor anti-freezing design to ensure that the sensor operates normally at a low temperature of -20 ℃, and at the same time introduces an ice-melting circuit to ensure that the instrument surface does not freeze in the spring and autumn freeze-thaw season; the main sensor of the buoy and the acquisition communication system The dual-machine working mode ensures the reliability of the system; in order to adapt to the harsh environment of the polar region, the buoy system first introduced wind power generation equipment to ensure energy supply under polar night conditions. The buoy is the first large-scale ocean observation buoy deployed in the polar region in my country, and the first large-scale buoy observation in the Norwegian Sea. After the buoys are deployed, the long-term observation data of the air-sea coupling in the Norwegian Sea can be obtained to understand the seasonal and inter-annual changes of the air-sea coupling state in the sea area, and to simulate the time change process of the global ocean conveyor belt and the hemispherical remote action process. And add these data to the global thermohaline circulation model and climate forecasting model to improve the level of ocean and climate forecasting in China, to improve the accuracy of climate forecasting, and to enhance the ability to guarantee national economic and social development, and to do research for global climate change. Contribute.
Lidar "scanning" PM2.5 in the laboratory of the Institute of Marine Instrumentation, Shandong Academy of Sciences. Under the operation of the staff, an atmospheric aerosol lidar is emitting dazzling blue light. It is understood that a stable mixture of a considerable number of solid particles and liquid particles (such as sea salt powder, dust, smoke and organic matter) suspended in the atmosphere and uniformly distributed is collectively called aerosol particles. This kind of radar is an active remote sensing monitoring device. It has the advantages of high spatial and temporal resolution, high measurement accuracy and three-dimensional scanning in the troposphere and stratosphere aerosol detection, which is difficult to compare with other detection methods. It can be equipped with ocean survey ships or special radar ships, etc., to carry out continuous, real-time and rapid remote sensing monitoring of marine atmospheric aerosols, and can quickly obtain its horizontal distribution and vertical structure, and then obtain the concentration and particles of marine atmospheric aerosol particles. Scale spectrum distribution and other related physical properties.
"By establishing China's independent marine atmospheric aerosol monitoring lidar network, not only can rapid and accurate monitoring of atmospheric aerosols over the ocean and prediction and warning of change trends be achieved, but with the frequent occurrence of haze weather across China, real-time aerosol 1. On-site monitoring (especially for the monitoring of PM2.5 aerosols with a particle size of less than 2.5 microns) is becoming more and more urgent. The role of this atmospheric aerosol lidar will become more and more apparent. Environmental issues, such as ozone destruction, acid rain formation, and smog events are closely related. As a global aerosol emitter, China's regional pollution problems caused by increased aerosols are becoming increasingly serious. The demand will exceed 3,000 units. In addition to the automatic booster for "volunteer" volunteer ships, the new automatic pilot meter developed by the institute can carry out meteorology (wind speed, wind direction, air temperature, humidity, air pressure, visibility), hydrology (water temperature, salinity), waves, The collection and observation of automatic observations of ocean currents, azimuths, etc. and manual observations of other weather conditions can also be used on offshore oil platforms and ocean and land monitoring stations as meteorological and hydrological observation instruments. The popularization and application of this instrument will enable relevant departments to obtain observation data in a more timely, stable and accurate manner. These data are not only extremely useful for scientific research and weather forecasting, but can also be applied to marine scientific surveys, petroleum exploration, fisheries fishing, marine aquaculture and other fields, and have important value for the development and application of marine living resources. At present, the automatic ship forecasting instrument developed by the institute has been installed and applied in many units such as the North Sea Ocean Forecast Center of the State Oceanic Administration, the South China Sea Forecasting Center of the State Oceanic Administration, and the Qingdao Ocean and Fishery Bureau. The economic and social benefits are very significant. Liu Mengde said that according to the plan requirements of the "Ocean Station and Voluntary Ship Observation System Construction Project", my country will gradually establish a complete set of volunteer ship observation system and data analysis and processing system, and continue to expand the number and scope of installation. As the country attaches more importance to and investment in the ocean, the voluntary ship automatic forecasting instrument has a broader
