Many outdoor radio systems transmit and receive signals that are sensitive to the climatic conditions, such as hydrometeor precipitation. For example, high frequencies may be heavily attenuated under periods of rain. According to climate reports the trend is towards more severe storms with heavy rainfall. An initial study of rainfall rate data from Norway supports the view that there is more often intense rainfall several places in the country.
Satellite communication networks are normally designed to deliver services also under severe propagation conditions. Links operating at 20 GHz can be severely affected by a number of atmospheric effects, where hydrometeor precipitation is often among the most severe ones.

The first LATICE seminar this fall will be held on the 10th of September 2020 with three talks on vegetation modeling and the carbon cycle.
Marine phytoplankton contribute nearly 50% to global primary production, support zooplankton production and play a vital role in regulating Carbon sequestration. Phytoplankton productivity fluctuations are caused by various direct and indirect effects of temperature, the balance of which show large-scale geographical patterns.
