Klimaatobservaties in Cabauw
...
Klimaatverandering grijpt diep op de samenleving in, maar de toekomstscenario's zijn nog niet zeker. We weten onvoldoende van de rol van bewolking en de hydrologische cyclus. Op het CESAR klimaatstation in Cabauw proberen we deze processen beter te begrijpen met geavanceerde meetapparatuur. We onderzoeken de interactie tussen wolken, aerosolen en s...
Diurnal and vertical variability of the sensible heat and carbon dioxide budgets in the atmospheric surface layer
The diurnal and vertical variability of heat and carbon dioxide (CO2) in the atmospheric surface layer are studied by analyzing measurements from a 213 m tower in Cabauw (Netherlands). Observations of thermodynamic variables and CO2 mixing ratio as well as vertical profiles of the turbulent fluxes are used to retrieve the contribution of the budget...
Cloud physical properties retrieval for climate studies using SEVIRI and AVHRR data = Afleiden van fysische eigenschappe...
Accurate and long term information on the physical properties of clouds is required to increase our understanding on the role of clouds in the current climate system, and to better predict the behavior of clouds in a changing climate. This thesis investigates if retrievals of cloud physical properties from satellite imagers can be used to prepare t...
Meteorological applications of a surface network of Global Positioning System receivers
This thesis presents meteorological applications of water vapour observations from a surface network of Global Positioning System (GPS) receivers. GPS signals are delayed by the atmo¬sphere due to atmospheric refraction and bending. Mapped to the zenith, this delay is called Zenith Total Delay (ZTD). The ZTD can be separated in a hydrostatic and a ...
Meten aan het klimaat : observeren om te kunnen participeren
Het Nederlandse klimaatbeleid wordt steeds meer onderbouwd met resultaten uit klimaatmodellen. Het vergelijken van de uitkomsten van deze modellen met meetgegevens is belangrijk om de kans op systematische fouten in de klimaatprojecties te minimaliseren. Dit themanummer van Geografie (ondersteund door Klimaat voor ruimte) staat stil bij de rol van ...
Climate change exacerbates the oak processionary caterpillar problem in The Netherlands
Since its first observation in the south of The Netherlands in 1991, the geographical range of the oak processionary caterpillar has increased steadily over the years, moving in north-eastern direction. It shows that it now occurs in the whole southern part of The Netherlands
De zonnestraling verandert, maar waarom? 80 jaar waarnemingen in Wageningen
De zon is de motor van ons klimaat en het leven op aarde. Hoeveel straling vangen we elk jaar op en hoe is die verdeeld over de seizoenen? Om hier achter te komen meet Wageningen al 80 jaar de zonnestraling aan de grond. De veranderingen in het stralingspatroon die door de tijd zijn waargenomen, blijven vooralsnog onverklaard
Automatic prediction of high-resolution daily rainfall fields for multiple extents: the potential of operational radar
This study investigates the added value of operational radar with respect to rain gauges in obtaining high-resolution daily rainfall fields as required in distributed hydrological modeling. To this end data from the Netherlands operational national rain gauge network (330 gauges nationwide) is combined with an experimental network (30 gauges within...
Diagnostic equations for the stable boundary-layer height: evaluation and dismensional analysis
The performance of diagnostic equations for the stable boundary layer height h is evaluated with four observational datasets that represent a broad range of latitudes, land use, and surface roughness. In addition, large-eddy simulation results are used. Special care is given to data-quality selection.The performance of diagnostic equations for the ...
