China Education News – China Education News Network (Reporter Ren Zaoxia) Recently, Professor Chang Liang from the School of Marine Science and Ecological Surrounding Environment of Shanghai Ocean University and co-authors based on multi-source satellites The platform’s remote sensing detection technology has made important research progress in the height characteristics of the Arctic atmospheric boundary layer and its interaction with sea ice. The relevant research results were published online in the “IEEE Transactions on Earth Science and Remote Sensing”.
The atmospheric boundary layer is the coupling of Arctic atmosphere-ocean-sea iceEthiopia Sugar DaddyThe extremely complex material and energy exchange area between systems, accurately detecting the structure of the Arctic atmospheric boundary layer and obtaining physical parameter characteristics is the key to establishing parameterization of the Arctic atmospheric boundary layerET Escorts The basis of the plan will help improve the ability to predict Arctic climate changes.
In view of the limitations of Arctic meteorological conditions and on-site observation conditions, the research team innovatively introduced the Global Positioning System (GPS) radio occultation technology and conducted experiments with on-site measurement results. The comparison proves that this technology can effectively carry out altitude detection of the Arctic atmospheric boundary layer and has the advantages of all-weather, large scale and high precision.
The research team collaborated with Ethiopians Sugardaddy to obtain the results obtained by the Atmospheric Infrared Sounding Satellite (AIRS). Results such as surface air temperature (SAT), atmospheric precipitable water vapor content (PWV) and cloud cover (CF) in the Arctic atmospheric boundary layer further analyze the height of the atmospheric boundary layer under different sea ice conditions in the Arctic Ocean. Relationship with Arctic surface conditions. The analysis found that PBLH over the Arctic Ocean has always been negatively correlated with SIC, and has always been positively correlated with SAT and PWV, but the response of PBLH to changes in SIC, SAT, and PWV changes with changes in Arctic sea ice conditions in each season. In addition, the unstable atmospheric boundary layer with higher altitude in the open waters of the Arctic Ocean usually corresponds to a thin and weak atmospheric inversion layer, while the atmospheric boundary layer with lower altitude in the solid ice area is often accompanied by a highly stable ground-attached layer. Temperature inversion, and the height of the atmospheric boundary layer in the ice edge zone is between that of open water and Ethiopia Sugar Daddy solid ice zone Transitional characteristics.
