Adaptation to climate change: assessment of urban vulnerability to heatwaves and extreme heat
 Suchá, Lenka ; Geletič, Jan ; Vaňo, Simeon ; Bašta, Petr ; Jančovič, M. ; Duchková, Helena
The methodology is focused on integrated modelling of climate change impacts on social-ecological systems in cities and on the methodological approach to vulnerability assessment of heatwaves and extreme heat at local and city scales. Recent approaches are often based on insufficient data where land use, land cover and distribution of population in space are considered as constant. This methodology then presents a complex approach to scenario building of future vulnerability of cities to heatwaves and extreme heat, that is based on data synthesis originating from spatial modelling and participatory processes. To this end, the methodology elaborates on the aspects of climate modelling, land use and land cover scenarios development and socio-demographic scenarios until the year 2050. The outcomes of the application of the methodology are a significant tool for urban adaptation planning in terms of adaptation measures allocation to the areas with recent and future sensibility to heat stress.

Score matching filters for Gaussian Markov random fields with a linear model of the precision matrix
 Turčičová, Marie ; Mandel, J. ; Eben, Kryštof
We present an ensemble filter that provides a rigorous covariance regularization when the underlying random field is Gaussian Markov. We use a linear model for the precision matrix (inverse of covariance) and estimate its parameters together with the analysis mean by the Score Matching method. This procedure provides an explicit expression for parameter estimators. The resulting analysis step formula is the same as in the traditional ensemble Kalman filter.
