Delft Measures Rain: A quality assessment of precipitation measurements from personal weather stations

Personal weather station (PWS) networks have the potential to supply precipitation data at high spatial and temporal resolution for urban hydrological modeling. Past research has shown promising results on the quality of PWS data, for example from Netatmo gauges, but studies on other PWS brands are limited. This thesis assesses the quality of...

A new Framework for assessing “The Value” of an Amateur Weather Station: Enabled by Web bots

A personal weather station (PWS) is a set of weather measuring instruments that is owned and operated by an individual, club, association, or business. Even tho these stations might be less advanced as the professional stations, the amount of amateur stations that are active is much higher. With these PWS networks in full effect and still...

Improving location accuracy of a crowdsourced weather station by using a point cloud: Use case based Netatmo on the Hague

The world’s continuously increasing population leads to environmental challenges, among which, the urban heat island effect has been recognized as one of the leading environmental issues recently. Using traditional weather station (usually one or two within one city and placed in rural area) to monitor and model the canopy layer urban heat...

The Potential of Citizen Observatories for Improving Spatial Measurements of Rainfall in Cities

Urban pluvial flooding occurs when the run-off converted rainfall exceeds the capacity of the sewer or stormwater system (Houston et al., 2011). This can result in damage to ecology, infrastructure, disruption to human activities, injuries and in the worst-case scenario, loss of life (Biniyam et al., 2017). With the expected increase in the...

Automated quality-control filters for undetected rainfall in citizen rain gauge data

Flooding in cities, known as Urban Pluvial Flooding (UPF), causes disruption of society, damage to cities and inconvenience for people. Cities are expected to become more vulnerable to UPF due to more frequent and more intense extreme rainfall events with high spatial variability as result of climate change. Additionally increasing urbanisation...

Development of a modular weather station

The TransAfrican Hydro Meteorological Observatory aims to create a dense weather station network in sub-Sahara Africa in order to obtain accurate climate data for a wide range of applications. Existing high-quality weather stations are very expensive and unaffordable for the African government or private parties. Therefore innovative sensors and...
