Atmospheric microplastic composition and concentration from an uncrewed aerial system

Data files: - Airborne_MP_count.xlsx – This file contains six columns: SampleID, Location, Filaments, Fragments, Filaments_corr, and Fragments_corr. It reports the microplastic particle counts by shape type (Fragments and Filaments), with the _corr columns showing values corrected using the blank controls. - Arvada_20240920_Raman (folder) – Contains 8 csv files generated by Raman microscopy, each including wavenumber and absorbance data. - Arvada_20241002_Raman (folder) – Contains 23 csv files generated by Raman microscopy, each including wavenumber and absorbance data. - Erie_20240919_Raman (folder) – Contains 11 csv files generated by Raman microscopy, each including wavenumber and absorbance data. - Erie_20241003_Raman (folder) – Contains 30 csv files generated by Raman microscopy, each including wavenumber and absorbance data. - Colorado_MP_flights_level_1 – This file contains eight columns: Time (MST), Time (UTC), readingPress, setpoint, outputVal, location, altitude, FLnumber. Time (MST) is the timestamp in second in Mountain Time (local time), Time (UTC) is the timestamp in second in UTC, readingPress is the value read from the pressure sensor, setpoint is the value sent from the microcontroller, outputVal is the value read from the micro blower, location is where the sUAS flights took place, altitude in m above ground level is the hovering altitude of the sUAS, FLnumber is the number identification of the sUAS flight. Small Uncrewed aerial system (sUAS) flight locations: Arvada, Colorado, UAS (39°50’32”N 105°13’09”W) Erie, Colorado, UAS (40°02’41” 104°59’01”W) The polymer identification used Raman microscopy at the Rhode Island Consortium for Nanoscience and Nanotechnology (RIN2), University of Rhode Island, Narragansett, RI, USA.数据集文件如下： - Airborne_MP_count.xlsx：该文件包含6列数据，分别为SampleID（样本编号）、Location（采样地点）、Filaments（丝状微塑料（microplastic）颗粒数）、Fragments（片状微塑料颗粒数）、Filaments_corr（校正后丝状微塑料颗粒数）以及Fragments_corr（校正后片状微塑料颗粒数）。其记录了按形状类型（丝状与片状）分类的微塑料颗粒计数结果，带_corr后缀的列代表通过空白对照校正后的数值。 - Arvada_20240920_Raman（文件夹）：包含8个由拉曼显微镜（Raman microscopy）生成的CSV文件，每个文件均包含波数（wavenumber）与吸光度（absorbance）数据。 - Arvada_20241002_Raman（文件夹）：包含23个由拉曼显微镜生成的CSV文件，每个文件均包含波数与吸光度数据。 - Erie_20240919_Raman（文件夹）：包含11个由拉曼显微镜生成的CSV文件，每个文件均包含波数与吸光度数据。 - Erie_20241003_Raman（文件夹）：包含30个由拉曼显微镜生成的CSV文件，每个文件均包含波数与吸光度数据。 - Colorado_MP_flights_level_1：该文件包含8列数据，分别为Time (MST)（山地标准时间戳，单位：秒）、Time (UTC)（协调世界时戳，单位：秒）、readingPress（压力传感器读取值）、setpoint（微控制器发送的设定值）、outputVal（微型鼓风机读取值）、location（小型无人航空系统（sUAS, Small Uncrewed aerial system）飞行地点）、altitude（悬停高度，单位：米，相对于地面海拔）以及FLnumber（小型无人航空系统飞行任务编号）。 小型无人航空系统飞行点位如下： - 科罗拉多州阿尔瓦达市无人航空系统飞行点位：北纬39°50′32″，西经105°13′09″ - 科罗拉多州伊利市无人航空系统飞行点位：北纬40°02′41″，西经104°59′01″ 聚合物鉴定工作由美国罗德岛大学纳拉甘西特分校罗德岛纳米科学与技术联盟（RIN2, Rhode Island Consortium for Nanoscience and Nanotechnology）采用拉曼显微镜完成。
