Leuven.cool citizen science urban weather station network: raw data

This repository contains the crowdsourced data from the Leuven.cool project, a citizen science network of around 110 low-cost weather stations (Fine Offset WH2600) distributed across Leuven, Belgium. The current repository contains the raw, unprocessed measurements, as received from the sensors. Data has a 16-second resolution. The dataset contains a total of 1,019,965,287 observations, covering the period from June 2019 to March 2025.

The processed, quality-controlled and bias-corrected dataset is published in this resource: Beele, Eva; Reyniers, Maarten; Aerts, Raf; Somers, Ben, 2022, "Replication Data for: Quality control and correction method for air temperature data from a citizen science weather station network in Leuven, Belgium", https://doi.org/10.48804/SSRN3F

Data is grouped into files, each covering a three-month period (calendar quarters). It is recommended to use the timestamp of the measurement's reception by the server (DATEUTC) as the valid timestamp. Missing values are represented as NULL.

The file STATIONS.csv contains metadata about the stations, with the following columns:

ID
unique identifier of the station used in RAWDATA files

WOWID
corresponding identifier in the UK Met Office's Weather Observations Website (WOW)

LATITUDE
latitude of the station

LONGITUDE
longitude of the station

ALTITUDE
altitude of the station
