A dataset of particulate matters measurements from a network of mobile and fixed sensors and monitoring stations in Rouen (France)
Description
Data was collected by ATMO Normandie comprising mobile and fixed measurements of particulate matters (PM) collected by means of low-cost sensors and monitoring stations. Data were collected in Rouen, France, over a 42-day period, from October 25, 2023 to December 6, 2023. This dataset consists of measurements made by three types of devices: - 3 monitoring stations. Two are urban traffic ones (named QDP, SUD3) and one (named JUS) is an urban background. Measurements are made every 15 minutes. - 22 AirSensEUR low-cost sensors located on traffic lights. Their measurements are made every minute. - 2 mobile low-cost sensors, of brand ATMOTrack. Sensors are located on public buses, and measurement are made every 10 seconds. The dataset consists of 70 .csv files, that can be divided into 4 groups. First, the table ‘coordinates.csv’ describe the coordinates of all fixed devices (the three monitoring stations and twenty-two AirSensEUR sensors). It is organized into three columns, namely ‘name’, ‘longitude’ and ‘latitude’, with longitude and latitude expressed in standard WGS84 system. Secondly, the file ‘reference_measures.csv’ address every measurement collected by a monitoring station. It consists of 7 columns. The first one, ‘time’, indicates the moment of measurement (format UTC±00:00:00), then each column is named as follows ‘AAA_T_PXX’ with ‘AAA’ the name of the station (SUD3, QDP or JUS), ‘T’ the brand of the station (‘T’ for TEOM, ‘B’ for BAM and ‘F’ for FIDAS) and XX the size of particulate matters. Indeed, PM10 correspond to particulate matter with diameter under 10 µm while PM2.5 have a diameter of less than 2.5 µm. Those columns contain PM measurements in µg/m3. The third type of document is for measurements from AirSensEUR sensors. Those files are named ‘ASEXX_YY.csv’, with ‘XX’ going from 4 to 13 (first wave of deployment) and from 40 to 53, with exception of 47 and 51 (second wave of deployment) and ‘YY’ being PM, GAS or MTO. Since there are 22 sensors, there are 66 of these files. Each one contains the column ‘date’ for the time of measurement (format UTC±00:00:00). PM files also contain columns ‘PM10’ and ‘PM2.5’ for particulate matters measurement in µg/m3. GAS contains the column ‘date’ and measurements of pollutants in columns ‘NO’, ‘NO2’, ‘Ox’, ‘CO’. Those four parameters are measured in µV. Finally, files labels ‘MTO’ contains the column ‘date’, ‘T’ for temperature in °C, ‘HR’ for relative humidity in % and PA for atmospheric pressure in hPa. Finally, the dataset is completed by two .csv files, named ‘ATM1.csv’ and ‘ATM2.csv’, each one dedicated to an ATMOTrack mobile sensor. Files contain the time of measurement (column ‘time’, format UTC±00:00:00), the coordinates of the sensor at that time (‘longitude’ and ‘latitude’ in standard WGS84 system), and measurements of PM2.5 (column ‘pm25’) and PM10 (column ‘pm10’) in µg/m3. Sensors also provide bus speed in km/h.

Steps to reproduce
Instruments connected to the ATMO Normandie network: - Low-cost sensors: 22 PM and Alphasense Chemical Sensors in AirSensEUR host (including PMS5003, NO2-B43F, NO-B4, CO-A4, OX-A431 and deported temperature, humidity and pressure sensors in each node). AirSensEUR is an Open Platform project, targeted to precise air quality measurements, developed by the Join Research Center in Ispra, in collaboration with Liberaintentio S.r.l. - Reference measures: 2 HORIBA APNA 370 (chemiluminescence) ambient NOx monitors, installed at traffic sites (named SUD3 and QDP), and an Environnement SA AC32e (chemiluminescence) ambient NOx monitor installed at JUS. - Latitude and longitude for those collected samples/data are given in coordinates.csv file. - Low-cost sensors: 2 mobile ATMOTrack sensors (see https://atmotrack.fr). Measurements, including GPS positions, are sent every 10 seconds to ATMOTrack database, and are retrieve online by ATMO Normandie.
