Abstract: Affordable and accurate weather monitoring systems are essential in low-income anddeveloping countries and, more recently, are needed in small-scale research such as precision agricultureand urban climate studies. A variety of low-cost solutions are available on the market, but theuse of non-standard technologies raises concerns for data quality. Research-grade all-in-one weatherstations could present a reliable, cost effective solution while being robust and easy to use. Thisstudy evaluates the performance of the commercially available ATMOS41 all-in-one weather station.Three stations were deployed next to a high-performance reference station over a three-month period.The ATMOS41 stations showed good performance compared to the reference, and close agreementamong the three stations for most standard weather variables. However, measured atmosphericpressure showed uncertainties >0.6 hPa and solar radiation was underestimated by 3%, which couldbe corrected with a locally obtained linear regression function. Furthermore, precipitation measurementsshowed considerable variability, with observed differences of 7.5% compared to the referencegauge, which suggests relatively high susceptibility to wind-induced errors. Overall, the station iswell suited for private user applications such as farming, while the use in research should considerthe limitations of the station, especially regarding precise precipitation measurements.
