AusPollen - Weekly Pollen Count - Rocklea, Brisbane, Queensland (Point) July 2016 - June 2020

The data set contains airborne pollen concentrations (grains per cubic meter) from samples taken at Rocklea, Queensland, Australia (-27.5351,152.9933) between October 2016 and June 2020. Each data row has two concentrations: one for grass (Poaceae) and one for all other pollens. 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2016年10月至2020年6月期间，于澳大利亚昆士兰州罗克利（Rocklea，坐标-27.5351,152.9933）采集的大气花粉浓度数据（单位：每立方米花粉粒数）。每条数据包含两类浓度：禾本科（Poaceae）牧草花粉浓度，以及其余所有花粉的浓度。为便于与其他数据集开展比对以及跨花粉季比较，数据周以每年7月1日为起始。花粉季结束时的剩余天数均归入第52周。每条数据包含采样时段起始日期、采样时段总天数（7~9天）以及实际采集并统计花粉的天数（0~9天）。如前文所述，浓度数值仅基于实际采集的天数，未必覆盖完整采样时段。

大气花粉样本采用容积式连续流撞击采样器（英国伯克德制造公司，Burkard Manufacturing）采集，以碱性品红（fuchsin）染色后，依据《澳大利亚大气花粉与孢子监测网络临时标准及规程（第二版，2018年9月14日）》（链接：https://www.allergy.org.au/hp/papers/australian-airborne-pollen-and-spore-monitoring-network-interim-standard-and-protocols）中的最佳实践规范，通过光学显微镜进行计数。

本数据集可用于大气牧草花粉、其余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病例的影响，或推断牧草与其他植被的生长模式。此外，数据还可用于评估随时间变化的中、长期趋势，或对比空间上相距较远的点位间的花粉暴露水平。

本数据集及澳大利亚花粉空气生物学协作网络（AusPollen Aerobiology Collaboration Network）其他监测站点的元数据，可于国家环境监测站点登记系统（链接：https://neii.gov.au/viewer/#share=s-vH6PEDVzXsMEIJcSRdZ5uaMcgP6）查询。关于其他监测花粉及孢子类别的信息，可通过澳大利亚花粉空气生物学协作网络物种分类体系，在澳大利亚研究数据共同体（ARDC）研究词汇表网站（链接：https://vocabs.ardc.edu.au/viewById/300）获取。

AURIN已基于花粉样本的坐标，为每条数据新增了纬度、经度及空间化几何列。无可用数据的时段均标记为空值（null）。
