OS data acquisition, management & standardization

The Citizen Science project Delft Measures in Delft (The Netherlands) engages residents in monitoring their local microclimate using low-cost weather stations installed in their gardens. The network currently consists of ~50 stations distributed across diverse neighbourhoods, capturing fine-scale variability in urban microclimates, with particular emphasis on rainfall. Unlike typical Private...

43. DISDRODB: a global database of raindrop size distribution observations

OS data acquisition, management & standardization

The drop size distribution (DSD) describes the number and size of raindrops in a volume of air. Knowledge of the DSD is key to model the propagation of microwave signals through the atmosphere (crucial for telecommunication, radar remote sensing and opportunistic rainfall sensing), to improve microphysical schemes in numerical weather prediction models, and to understand rain-related land...

47. A demo of the GMDI-CAP system for scalable global microwave link data collection and processing.

OS data acquisition, management & standardization

As a strategic outcome of the COST Action OpenSense we have started on setting up the Global Microwave Data Collection Initiative (GMDI) via the SetGMDI project, funded via the COST Innovators Grant. Our goal is to address the issue that CML-based rainfall observation is still hindered by legal, business and organizational barriers. Within the SetGMDI consortium, comprising mobile network...
