In her current research project, she investigates how AI can be used to improve the understanding of key variables in the upper atmosphere. This can contribute to more accurate models of the space environment where satellites operate and provide better insight into the conditions that may affect satellite performance, communication systems, and space-based infrastructure.<\/p>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading gp-gutenbergpro-11f78\">Combining AI and physical models<\/h2>\n\n\n\n<p class=\"gp-gutenbergpro-1ec22 wp-block-paragraph\">A key part of the project is the combination of several different data sources. Satellite measurements, solar activity data and ionospheric data each contribute with important information. When these data sources are used together, the AI model can improve the physical model significantly. According to Lotte, this combination is one of the central insights of the project so far:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"gp-gutenbergpro-8c8fe wp-block-paragraph\">\u201cA key insight is combining different data sources really matters. Satellite measurements, solar activity, and ionospheric data each add something unique. When I use them together in AI on top of the physical model, the model improves significantly.\u201d<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading gp-gutenbergpro-413d2\">Using UCloud as the primary platform<\/h2>\n\n\n\n<p class=\"gp-gutenbergpro-4f589 wp-block-paragraph\">Lotte has used UCloud as the primary platform for running the computational work in the project. A large part of this involves training AI models, which requires substantial computing power because the datasets are large and the models need many iterations to find the right architecture. However, UCloud has not only been used for the heavy computations at the end of the process. It has also supported the development and testing of code along the way.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"gp-gutenbergpro-9b348 wp-block-paragraph\">\u201cIt gives me a good environment to build the workflow, try things out, and adjust as I go.\u201d<\/p>\n<\/blockquote>\n\n\n\n<p class=\"gp-gutenbergpro-1492c wp-block-paragraph\">Lotte also uses UCloud in another research project, where large language models are used to work with environmental data. Across both projects, access to computing power has been essential.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"gp-gutenbergpro-ce219 wp-block-paragraph\">\u201cIn both projects, we simply could not have done the work without access to this kind of computing power or a similar alternative.\u201d<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading gp-gutenbergpro-ef564\">Access to computing power made results possible faster<\/h2>\n\n\n\n<p class=\"gp-gutenbergpro-9f0b5 wp-block-paragraph\">When Lotte moved from industry into academia, she was concerned about whether she would have access to enough computing power for her research. Discovering that UCloud existed was therefore an important advantage.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"gp-gutenbergpro-0ecd5 wp-block-paragraph\">\u201cIt was really nice to discover that UCloud existed. Having access to that number of resources has been a big advantage for the project.\u201d<\/p>\n<\/blockquote>\n\n\n\n<p class=\"gp-gutenbergpro-9660b wp-block-paragraph\">With UCloud, Lotte could access the computing power needed without first having to apply for separate funding. This made it possible to move faster from development to results.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"gp-gutenbergpro-0bd39 wp-block-paragraph\">\u201cIf I did not have access to UCloud or another free service, and first had to apply for funding just to get compute, it would have been impossible to have results so fast.\u201d<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading gp-gutenbergpro-c5f56\">A user-friendly platform for research<\/h2>\n\n\n\n<p class=\"gp-gutenbergpro-31030 wp-block-paragraph\">According to Lotte, one of the main benefits of UCloud is its user-friendly setup for research and development work.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"gp-gutenbergpro-49ef3 wp-block-paragraph\">\u201cFirst of all, UCloud is really well-suited for development work. It gives me a good environment to build and test my workflow, and for research work, I have found that it has a very user-friendly interface.\u201d<\/p>\n<\/blockquote>\n\n\n\n<p class=\"gp-gutenbergpro-82f1a wp-block-paragraph\">She has used Visual Studio Code, a code editor used for writing, testing and developing code, on UCloud, which gives her a setup similar to the one she uses locally. This makes it easier to move between local development and cloud-based work. Another important advantage has been the possibility to scale up and access more compute when needed.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"gp-gutenbergpro-b342f wp-block-paragraph\">\u201cIt has been very easy to scale up and get more compute when I need it.\u201d<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading gp-gutenbergpro-d8fb2\">Fast support makes a difference<\/h2>\n\n\n\n<p class=\"gp-gutenbergpro-91b1d wp-block-paragraph\">For Lotte, the support around UCloud has also been an important part of the experience. When working with complex research projects, technical issues can slow down the research process. In her experience, the support team has responded quickly when challenges have occurred.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"gp-gutenbergpro-8f4d2 wp-block-paragraph\">\u201cIf I run into any issues, the team helps almost immediately. That makes a big difference when working on complex projects.\u201d<\/p>\n<\/blockquote>\n\n\n\n<p class=\"gp-gutenbergpro-bb891 wp-block-paragraph\">Lotte has received support from Aalborg University\u2019s local front office, which helps researchers get started with UCloud and provides support when questions or technical issues arise. All Danish universities have a local front office where researchers can get support.<\/p>\n\n\n\n<p class=\"gp-gutenbergpro-21f95 wp-block-paragraph\">Overall, UCloud has provided Lotte with access to the computing resources, development environment and support needed to work with large datasets, AI models and complex research workflows.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"gp-gutenbergpro-b19f2 wp-block-paragraph\">\u201cI think UCloud is a really good solution overall. When people talk about the need for more European cloud alternatives, this is the kind of thing I think of.\u201d<\/p>\n<\/blockquote>\n\n\n\n<div class=\"wp-block-columns gp-gutenbergpro-2585b is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column gp-gutenbergpro-2b869 is-layout-flow wp-block-column-is-layout-flow\">\n<p class=\"gp-gutenbergpro-600e6 wp-block-paragraph\">This work was supported by DeiC National HPC (g.a.
