Title: Spatial Variation of the Amsterdam Heat Island

Abstract:In 2014 24 meteorological stations were installed in Amsterdam and they have been operating to this day. These stations provide measurements of the urban climate with an unprecedented spatial resolution. This presentation will give an overview of analysis performed on five years of summer data from these stations. The presentation will give conclusions on the locations in Amsterdam that experience the
greatest heat and to which urban elements this heat can be attributed.

Title: Simulating European croplands with the Simple Biosphere Model v4

Abstract:The Simple Biosphere model version 4 (SiB4) is developed and tested in the mid-west of the U.S. It can simulate generic C3 and C4 crops and three specific crop types(maize, soybean and winter wheat). However, the parameters used to simulate these crops are tuned to the U.S. In this study, I have improved the fluxes of European croplands that are simulated with the SiB4 model by using several parameters of the WOFOST model (a crop production model designed and implemented in Europe for over 30 years). I have used both the default SiB4 model and the adapted version to simulate the crop yield, and carbon and energy fluxes. These fluxes and the yield are compared to observations during normal years (2004-2017) and a dry year (2018) for the whole of Europe The Simple Biosphere model version 4 (SiB4) is developed and tested in the mid-west of the U.S. It can simulate generic C3 and C4 crops and three specific crop types (maize, soybean and winter wheat).
