Tämä tutkimus käsittelee kansainvälisen polaarivuoden 1932–1933 aikana toimineen Petsamon magneettisen observatorion havaintotuloksia. Mukana on lyhyt katsaus polaarivuoden aikana ja sen jälkeen uudella suomalaisella meteorologisella radiosond

This thesis presents research on two topics related to sea level in the Baltic Sea: regional sea level rise and meteotsunamis, i.e. meteorologically generated tsunami waves. While these phenomena act on very different time scales, they are both relev

Waves are important for both the leisure and safety of the human population. Open-sea waves have been studied since the 1940’s and their central properties are known. The wave field is described by the so called wave spectrum, which is a decomposit

Information on snow water equivalent (SWE) of seasonal snow is used for various purposes, including long-term climate monitoring and river discharge forecasting. Global monitoring of SWE is made feasible through remote sensing. Currently, passive mic

Optical snow monitoring methods have tendency to underestimate snow cover beneath the evergreen forest canopy due to the masking effect of trees. There is need to develop method for providing more reliable snow products and enhance their use e.g. in

The topic of this dissertation is the seasonal snow surface roughness and albedo. These are studied using optical satellite data and terrestrial laser scanning. The use of remote sensing data requires knowledge on the optical properties of the measur

The processes related to urban development (urbanisation, densification, irrigation and worsened air quality) are assumed to affect the urban hydrological cycle, but little is known about the impact of the individual processes. One of the reasons for

The hydrological regime is highly dependent on climatic conditions. In a boreal snow-driven region, such as Finland, changes in the winter and spring climatic seasonal conditions have a large effect on the hydrology. In this study, long-term changes
