Affordable and accurate weather monitoring systems are essential in low-income and developing countries and, more recently, are needed in small-scale research such as precision agriculture and urban climate studies. A variety of low-cost solutions are available on the market, but the use of non-standard technologies raises concerns for data quality. Research-grade all-in-one weather stations could present a reliable, cost effective solution while being robust and easy to use. This study 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 agreement among the three stations for most standard weather variables. However, measured atmospheric pressure showed uncertainties >0.6 hPa and solar radiation was underestimated by 3%, which could be corrected with a locally obtained linear regression function. Furthermore, precipitation measurements showed considerable variability, with observed differences of ±7.5% compared to the reference gauge, which suggests relatively high susceptibility to wind-induced errors. Overall, the station is well suited for private user applications such as farming, while the use in research should consider the limitations of the station, especially regarding precise precipitation measurements.
在低收入和发展中国家，负担得起且准确的气象监测系统至关重要，而在最近，在小规模研究中，如精准农业和城市气候研究中，也需要这些系统。市场上有各种低成本的解决方案，但非标准技术的使用引起了人们对数据质量的担忧。研究级的一体化气象站可以提供可靠、经济高效的解决方案，同时具有坚固耐用且易于使用的特点。本研究评估了市售的 ATMOS41 一体化气象站的性能。三个气象站在三个月的时间内部署在高性能参考站旁边。与参考站相比，ATMOS41 站表现出良好的性能，并且大多数标准气象变量在三个站之间具有很好的一致性。然而，测量的大气压力显示出>0.6 hPa 的不确定性，并且太阳辐射被低估了 3%，这可以通过本地获得的线性回归函数进行修正。此外，降水测量显示出相当大的可变性，与参考雨量计相比，观测到的差异为±7.5%，这表明对风引起的误差相对敏感。总的来说，该站非常适合私人用户应用，如农业，而在研究中使用时应考虑到该站的局限性，特别是在精确的降水测量方面。
