R code to analyse air pollution hourly data from Catalunya from Gencat and Meteocat servers.
You only need to do minor edition at Visual Code Studio to adapt the code to your city databases and to call not my data but your own data from RStudio e.g. source("C://...datamanipulation.R") or source("https://raw.githubusercontent.com/drfperez/openair/main/datamanipulation.R") Air pollutant hourly data are from Martorell starting 1991 until 2022 available in the file city.csv obtained from XVPCA Gencat server. Half-hourly data is combined with wind direction (variable code 30) and wind speed (variable code 31) from Castellbisbal (station code XC) from 20/05/2009 (https://raw.githubusercontent.com/drfperez/openair/main/wind.csv) available at XEMA Meteocat server: https://analisi.transparenciacatalunya.cat/Medi-Ambient/Dades-meteorol-giques-de-la-XEMA/nzvn-apee/data Find the list of XEMA meteo stations at https://www.meteo.cat/observacions/llistat-xema containing half-hourly wind data Find the air pollutants hourly data at https://mediambient.gencat.cat/ca/05_ambits_dactuacio/atmosfera/qualitat_de_laire/vols-saber-que-respires/descarrega-de-dades/descarrega-dades-automatiques/
