AusPollen - Weekly Pollen Count - Parkville site, Melbourne, Victoria (Point) July 2016 - June 2020

The data set contains airborne pollen concentrations (grains per cubic meter) from samples taken at Parkville site, Melbourne, Australia (-37.7971, 144.9649) between July 2016 and June 2020. Each data row has two concentrations: one for grass (Poaceae) and one for all other pollen. For comparison with other data sets and between pollen seasons the data weeks start at July 1 each calendar year. Extra days at the end of the pollen year are included in week 52. Each data row has a collection period start date, the number of days within the collection period (7-9), and the number of days on which pollen was collected and summed (0-9). Concentrations represent only the number of days collected and not always the full collection period, as indicated. \n\nAirborne pollen samples were collected using a volumetric continuous flow impaction sampler (Burkard Manufacturing, UK), stained with fuchsin and counted by light microscopy according to best practice described in the [Australian Airborne Pollen and Spore Monitoring Network Interim Standard and Protocols (Version 2, 14 September 2018)](https://www.allergy.org.au/hp/papers/australian-airborne-pollen-and-spore-monitoring-network-interim-standard-and-protocols).\n\n Data may be used for modelling and forecasting airborne grass, other, total pollen levels. Other uses include analysis of the effect of pollen levels on asthma and allergy presentations, or in inference of grass and other vegetation growth patterns. Data may also be used for evaluation of medium or long-term trends over time or comparison withpollen exposure levels between spatial distant locations.\n\n Metadata about this and other AusPollen Aerobiology Collaboration Network monitoring sites is provided on the [National Environmental Monitoring Site Register](https://neii.gov.au/viewer/#share=s-vH6PEDVzXsMEIJcSRdZ5uaMcgP6). Information about other pollen and spores monitored can be found by the AusPollen Aerobiology Collaboration Network Species Classification on the [ARDC Research Vocabularies site](https://vocabs.ardc.edu.au/viewById/300).\n\nAURIN has added latitude, longitude and spatialised geometry columns for each row based on the coordinates of the pollen samples. Periods over which no data is available are marked as null.\n\n

本数据集包含澳大利亚墨尔本帕克维尔监测点（坐标：-37.7971, 144.9649）于2016年7月至2020年6月间采集的空气花粉浓度数据，浓度单位为粒/立方米（grains per cubic meter）。每条数据包含两类花粉浓度：一类为禾本科（Poaceae）草本花粉浓度，另一类为其余所有花粉的总浓度。为便于与其他数据集比对以及花粉季间的横向比较，数据周以每个日历年的7月1日为起始。花粉季末尾的额外天数均归入第52周。每条数据包含采样周期起始日期、采样周期内总天数（7-9天）以及实际完成花粉采集并计数的天数（0-9天）。如标注所示，浓度数值仅反映实际采集花粉的天数，而非采样周期的完整时长。

空气花粉样本采用容积式连续流撞击采样器（volumetric continuous flow impaction sampler）采集，由英国Burkard Manufacturing公司生产；样本使用品红染色，随后通过光学显微镜进行计数，计数流程遵循《澳大利亚空气花粉与孢子监测网络暂行标准及规程（2018年9月14日，第2版）》[Australian Airborne Pollen and Spore Monitoring Network Interim Standard and Protocols (Version 2, 14 September 2018)]中的最佳实践规范，相关标准链接：https://www.allergy.org.au/hp/papers/australian-airborne-pollen-and-spore-monitoring-network-interim-standard-and-protocols。

本数据集可用于空气草本花粉、其他花粉及总花粉浓度的建模与预测。其他应用场景包括：分析花粉浓度对哮喘及过敏就诊量的影响，或推导草本植物与其他植被的生长模式。此外，该数据集还可用于评估花粉浓度的中长期时间趋势，或是比对不同空间区位的花粉暴露水平。

本监测点及澳大利亚花粉空气生物学协作网络（AusPollen Aerobiology Collaboration Network）其他监测点的元数据，可于国家环境监测点位登记系统[National Environmental Monitoring Site Register](https://neii.gov.au/viewer/#share=s-vH6PEDVzXsMEIJcSRdZ5uaMcgP6)查询。关于其他监测花粉与孢子的分类信息，可通过该网络的物种分类体系，在ARDC研究词汇表网站[ARDC Research Vocabularies site](https://vocabs.ardc.edu.au/viewById/300)获取。

AURIN平台已根据花粉样本的坐标信息，为每条数据新增了纬度、经度及空间化几何特征列。无有效数据的时段将以空值（null）标记。
