Accurate monitoring is critical for better understanding cities’ microclimate conditions and safeguard citizens’ health. Previous studies have performed microclimate analyses of urbanized areas by implementing data from either stable meteorological stations or satellites, or by developing mobile stations. Here, we present a vehicle-based monitoring campaign capable of monitoring both the scalar and directionally dependent variables that regulate the canopy layer environment. Under this framework, we performed a monitoring campaign within an Italian city, and measured simultaneously air temperature (± 0.3 \(^\circ \hbox {C}\) @ 20 \(^\circ \hbox {C}\)), relative humidity (± 2% @ 20 \(^\circ \hbox {C}\)), directional shortwave radiation (calibration uncertainty: < 1.8%), CO\(_2\) (± 50 ppm +2%) and PM10 (< 1%) concentration, wind speed (± 3% @ 40 m/s) and direction (± 3\(^\circ\) @ 40 m/s), and specific location (latitude, longitude and elevation). The presented assessment can be carried out within almost any area that motorized vehicles are allowed to access (e.g. through public transportation vehicles). Its application together with other mobile stations that can specifically assess also pedestrian areas, such as footpaths, urban parks, sidewalks and bike paths, as well as fixed meteorological stations and remote sensing techniques can contribute to a better understanding of microclimate patterns and hence to more efficient urban planning and risk assessments.

准确的监测对于更好地了解城市的小气候条件和保障市民的健康至关重要。以前的研究通过实施来自稳定气象站或卫星的数据，或通过开发移动站，对城市化地区进行了小气候分析。在这里，我们提出了一个基于车辆的监测活动，能够监测调节冠层环境的标量和方向因变量。在这个框架下，我们在意大利城市进行了一项监测活动，同时测量了气温（± 0.3 \(^\circ \hbox {C}\) @ 20 \(^\circ \hbox {C}\)），相对湿度 (± 2% @ 20 \(^\circ \hbox {C}\))、定向短波辐射（校准不确定性：< 1.8%）、CO \(_2\) (± 50 ppm +2%) 和 PM10 (< 1%) 浓度、风速 (± 3% @ 40 m/s) 和方向（± 3 \(^\circ\) @ 40 m/s）和具体位置（纬度、经度和海拔）。所提出的评估几乎可以在允许机动车辆进入的任何区域内进行（例如通过公共交通工具）。它与其他可以专门评估步行区的移动站（如人行道、城市公园、人行道和自行车道）以及固定气象站和遥感技术一起应用，有助于更好地了解小气候模式，从而更多有效的城市规划和风险评估。
