Luftdaten.Info data set 2016 - 5min, 30min values

The data set contains the normalized averaged 5 and 30 minutes value of the Sensor.Community - archives, formerly Luftdaten.info, of the year 2016. The tar-archive includes the CSV-files, XZ-compressed. For each sensor and day, the averaged values are available and each CSV-file contains a header. For particulate matter data (sensors: PPD42NS,SDS011):<br> <em>timestamp,sensor_id,location,lat,lon,P1,durP1,ratioP1,P2,durP2,ratioP2</em> Description: timestamp: Date and Time of measurement sensor_id: ID of Sensor lat: Latitude lon: Longitude P1: value of Particle Matter 10µg/m³ (PM10) durP1: ratioP1: P2: value of Particle Matter 2.5µg/m³ (PM2.5) durP2: ratioP2:本数据集包含2016年Sensor.Community（前身为Luftdaten.info）归档中的传感器归一化5分钟与30分钟均值数据。该TAR归档包含经XZ压缩的CSV格式文件，每个传感器每日的均值数据均可获取，且所有CSV文件均带有表头。针对颗粒物传感器（型号为PPD42NS、SDS011），其CSV文件的字段依次为：timestamp、sensor_id、location、lat、lon、P1、durP1、ratioP1、P2、durP2、ratioP2。各字段说明如下：timestamp为测量日期与时间；sensor_id为传感器唯一标识；lat为纬度；lon为经度；P1为粒径10μm的颗粒物（PM10）浓度，单位为μg/m³；P2为粒径2.5μm的颗粒物（PM2.5）浓度，单位为μg/m³；location、durP1、ratioP1、durP2、ratioP2未在原始描述中给出具体含义。
