Description

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

The following columns are available in the RAWDATA*csv files:

Column name Description Unit
OBSID unique identifier of the measurement -
ID station identifier in file STATIONS.csv -
TEMPF temperature Fahrenheit
HUMIDITY relative humidity %
DEWPTF dew point temperature Fahrenheit
WINDCHILLF wind chill Fahrenheit
WINDDIR wind direction degrees, 0-360
WINDSPEEDMPH wind speed mph
WINDGUSTMPH wind gust speed mph
RAININ rain intensity inch per hour
DAILYRAININ rain day total inch
SOLARRADIATION solar radiation W/m²
UV UV index -
BAROMIN air pressure inches of mercury
DATEUTC timestamp of reception of measurement by the server UTC
DATEUTC_STAT timestamp of measurement as reported by the station UTC

 

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
