If your plot is close to one of the CRA-W's 33 Pameseb stations, visit Agromet.be to view or download reference observations for the agricultural sector. The project has led to improvements in data quality control, thanks in particular to an automatic inconsistency detection algorithm. Data quality is ensured through preventive maintenance (i.e. before problems arise) and regular sensor recalibration. New rain gauges, based on our state-of-the-art weighing system, are also currently being installed.
If your plot is further away, you can use spatialised data per km², or "virtual weather stations". Spatialised data for temperature and humidity are available on Agromet.be. They are calculated using topography and data from several nearby stations.
Note that spatialised data are not available for very local weather variables such as rainfall. A potential solution could be to install your own connected weather station. There are some affordable models now available on the market and we've been studying their quality. They are reliable for recording rainfall, but it's important to check regularly that the rain gauge isn't clogged. Temperature measurements are reliable, but biases of over 10% have been observed for humidity. This variable is the most difficult to measure.
Have you taken the plunge and bought a station? Contact us to try out our new tools: automatic quality control of your data and cartographic analysis of the siting quality of your weather station.
