In order to advance the skill of short-term weather forecasting, the quality of data in the planetary boundary layer must be improved. Observations from ground stations and sparse radiosondes are no longer sufficient to properly describe the dynamics of the lower atmosphere and allow increasingly high-resolution numerical weather prediction (NWP) models to better predict future development. To address this, Meteomatics has been operating rotary wing UAVs to routinely profile the lower atmosphere for the last several years. It has been shown that assimilated Meteodrone profiles only ever have a positive or strongly positive effect on NWP modelling (particularly around fog and low cloud) with zero negative impacts. These results were presented at this year's 7th ISARRA conference in Lugo by Meteomatics CTO, Christian Schluchter.

The prospect of climate change and its consequences for the environment and communities requires political and economic action to help reduce the magnitude of change. Decisions about such actions require a solid factual base, and consequently we need a better understanding of the magnitude and pace of climate change-related modifications in the atmosphere and natural ecosystems. This requires environmental observations and monitoring at a wide range of temporal and spatial scales. ISARRA is society for researcher around the world using unmanned aircraft to observe and monitor, and to collect measurements. ISARRA is open to individuals as members and organizes a yearly conference to provide a forum for discussions and exchange of knowledge and experience. (cf. http://www.isarra.org/)
