| ===== Scientific Goals ===== | ===== Scientific Goals ===== |
| Within (AC)³, researchers at the University of Cologne, University Bremen, and AWI characterize the thermodynamic structure, clouds, aerosols, and trace gases in the atmospheric column at Ny-Ålesund on a long-term basis. In Cologne, the research focus is on remote sensing of the thermodynamic structure, water vapor, cloud macro- and microphysical properties and precipitation by combining the established observations at AWIPEV and Uni Cologne instrumentation, e.g., a cloud radars, micro rain radar. | |
| The ground-based observations at Ny-Ålesund are accompanied by satellite, aircraft, and ship measurements, as well as modeling studies on various scales. | |
| |
| Specific scientific questions are | |
| * To what extent and with which accuracy can we gain insight into the thermodynamic, trace gas, aerosol, and cloud macro- and microphysical properties at Ny-Ålesund? | |
| * What is their impact on the radiation and energy budget throughout the vertical extent from the surface to the lower mesosphere? | |
| * How do Arctic low-level clouds respond to global climate change? | |
| * How representative are the Ny-Ålesund observations across other Arctic sites? | |

| A list of the project related publications can be found [[https://geomet.uni-koeln.de/forschung/gruppe-crewell/arctic-ground|here]]. | "Cloud and Precipitation Observations, Modeling, And Prediction in Svalbard" (CLOUDMAPS) is a collaborative Arctic research network focused on improving the monitoring, understanding, and prediction of clouds and precipitation in Svalbard. It is funded by the Research Council of Norway. By integrating advanced observations, high-resolution modeling, and operational forecasting expertise, the project enhances knowledge of Arctic weather processes, supports improved weather prediction for aviation and society, and strengthens cooperation and data sharing between research institutions in Ny-Ålesund and Longyearbyen. CLOUDMAPS is a joint effort by MET Norway, UNIS, the University of Cologne, and the Norwegian University of Life Sciences. |
