To study and understand the importance of Internet of Things-driven citizen science (IoT-CS) combined with data satisficing, we set up and undertook a citizen science experiment for air quality (AQ) in four Pakistan cities using twenty-one volunteers. We used quantitative methods to analyse the AQ data. Three research questions (RQ) were posed as follows: Which factors affect CS IoT-CS AQ data quality (RQ1)? How can we make science more inclusive by dealing with the lack of scientists, training and high-quality equipment (RQ2)? Can a lack of calibrated data readings be overcome to yield otherwise useful results for IoT-CS AQ data analysis (RQ3)? To address RQ1, an analysis of related work revealed that multiple causal factors exist. Good practice guidelines were adopted to promote higher data quality in CS studies. Additionally, we also proposed a classification of CS instruments to help better understand the data quality challenges. To answer RQ2, user engagement workshops were undertaken as an effective method to make CS more inclusive and also to train users to operate IoT-CS AQ devices more understandably. To address RQ3, it was proposed that a more feasible objective is that citizens leverage data satisficing such that AQ measurements can detect relevant local variations. Additionally, we proposed several recommendations. Our top recommendations are that: a deep (citizen) science approach should be fostered to support a more inclusive, knowledgeable application of science en masse for the greater good; It may not be useful or feasible to cross-check measurements from cheaper versus more expensive calibrated instrument sensors in situ. Hence, data satisficing may be more feasible; additional cross-checks that go beyond checking if co-located low-cost and calibrated AQ measurements correlate under equivalent conditions should be leveraged.
为了研究和理解物联网驱动的公民科学(IoT-CS)与数据满足相结合的重要性,我们在巴基斯坦的四个城市设立并进行了一项空气质量(AQ)的公民科学实验,共有 21 名志愿者参与。我们使用定量方法分析了 AQ 数据。提出了三个研究问题(RQ)如下:哪些因素影响 CS IoT-CS AQ 数据质量(RQ1)?如何通过解决科学家、培训和高质量设备的缺乏问题使科学更具包容性(RQ2)?缺乏校准数据读数能否克服,从而为 IoT-CS AQ 数据分析产生有用的结果(RQ3)?为了解决 RQ1,对相关工作的分析表明存在多个因果因素。采用良好实践指南来提高 CS 研究中的数据质量。此外,我们还提出了一种 CS 仪器分类方法,以帮助更好地理解数据质量挑战。为了回答 RQ2,我们进行了用户参与研讨会,作为使 CS 更具包容性并培训用户更清楚地操作 IoT-CS AQ 设备的有效方法。为了解决 RQ3,我们提出了一个更可行的目标,即公民利用数据满足感,以便 AQ 测量可以检测到相关的本地变化。此外,我们提出了一些建议。我们的首要建议是:应培养深入的(公民)科学方法,以支持更具包容性、更有知识的大规模科学应用,造福大众;在现场,交叉检查更便宜的与更昂贵的校准仪器传感器的测量值可能既不有用也不可行。因此,数据满足可能更可行;应利用超出检查在等效条件下低成本和校准的 AQ 测量值是否相关的额外交叉检查。
