# README

This folder contains datasets of rainfall observations from Netatmo personal weather stations, provided as supplementary material for the manuscript "Crowdsourced personal weather stations show great potential for operational rainfall monitoring", submitted to Geophysical Research Letters by De Vos, et al. (2019).

These files contain the observations and meta information of a subset of the total number of personal weather stations that yields valuable rainfall observations during the study period and within the study area. The raw observations are collected, owned and provided by the Netatmo Company. To obtain data of other weather variables, study areas and/or periods, please consult the Netatmo public API (https://dev.netatmo.com/en-US/resources/technical/reference/weatherapi), or contact the Netatmo Company directly.

 

# Data format # 
- AMS_dataset.csv and NL_dataset.csv contain tables with time series at 5 min temporal resolution constructed from rainfall observations by Netatmo personal weather stations as collected on the Netatmo Weathermap. The raw time series have update frequencies that are not synchronized between stations and time intervals vary. In order to homogenize the dataset, observations are attributed to the end time stamp of the 5 min interval in which they were reported to the Netatmo Weathermap platform. Multiple observations within the 5 min interval are summed. Intervals without observations are indicated by 'NA'. The first column of the csv-file indicate the end time of the 5 min intervals in UTC. All subsequent columns contain the station rainfall observations in mm. 

- Ams_metadata.csv and NL_metadata.csv report the station IDs, corresponding with those in respectively AMS_dataset.csv and NL_dataset.csv, as well as their locations in longitude and latitude.
