Jan Peter George
In this talk Jan Peter George will introduce the datasets used in the Mobilitas Project “How dry is too dry? Quantifying the adverse effects of droughts for European forests across the last two decades”. He will talk about latest MODIS products that provide integrated land information such as net primary productivity and show illustrative examples how to link those data with environmental variables. Secondly, I will present tree mortality data from the ICP Forest network covering entire Europe and show how these data can be utilized for monitoring a prominent tree disease (ash dieback) at continental scale.

Remote sensing applications in agriculture, land cover change monitoring and vegetation phenology can benefit from higher temporal frequency radiometrically accurate imaging. Therefore, at UT Tartu Observatory, we are developing the new scientific-grade miniaturised multispectral imager Theia. Generally, when nanosatellites fly cameras, they are meant for aesthetic images without considering the data's radiometric quality. With Theia, we are developing an instrument with a 5% radiometric accuracy throughout its three-year lifetime. In this presentation, I will introduce Theia, how we plan to achieve our goals and what the future holds for the imager. The instrument website is at http://tospexgroup.space/node/9.

In 2019, the European Space Agency selected its latest planetary mission: the multi-spacecraft Comet Interceptor. The project’s primary goal after launch in 2029 is to characterise, for the first time, a long-period comet, preferably approaching the Sun for the first time. This planned flyby promises to provide us with valuable data to complement information gathered by all previous comet missions; all past projects have studied comets that have been altered by passing near the Sun many times. The mission will comprise a main spacecraft and two smaller probes, one of which will be provided by the Japanese space agency, JAXA. We’ll explore the challenges of planning a mission to an unknown target, how our comet target is to be selected, and the exciting measurements that the mission team plan to make. The mission website is at www.cometinterceptor.space.
