An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without a human pilot aboard. Unlike manned aircraft, UAVs were originally used for missions too "dull, dirty, or dangerous" for humans. While they originated mostly in military applications, their use is rapidly expanding to commercial, recreational, agricultural, and scientific applications. Many modern scientific experiments use UAVs as a tool to collect different types of data. Their flexibility and relatively simple use allow scientists to accomplish tasks that previously required expensive equipment like piloted aircrafts, gas or hot air balloons. The industry offers now many different types of UAVs with different characteristics and capabilities. At this session, we would like people to share their experience in using UAVs for scientific researches. We are interested to hear about particular scientific tasks, types of UAVs they use and instruments that were deployed.
