A collection of functions to download, filter and preview the latest ESA Copernicus 5p files produced for a specific location of the world. get5p {get5p} Get a specific S5p product Description The functions works after get5plist() function, it retrives a specific S5P product and allows to save it Usage get5p(month, year, number, id, fn) Arguments month Desired month in mm format (April would be “04”, December would be “12”) year Desired year in yyyy format (“2020” not “20”) number Desired .csv file index (from 1 to the maximum number of files returned by listlast() function) id Desired S5P file index (from 1 to the maximum number of files returned by get5plist() function) fn Desired name of the file to be used when saving the product to the local working directory Examples get5p(“04”,”2020”,”3”,”1”,”lastday.ncf”) — get5plist {get5p} Get a list of 5p products Description The functions works after listlast(month, year) function. After retrieving the list of available .csv files with listlast(), the get5plist() functions allows to retrieve a list of the available products described inside a specific .csv file. Usage get5plist(month, year, number) Arguments month Desired month in mm format (April would be “04”, December would be “12”) year Desired year in yyyy format (“2020” not “20”) number Desired .csv file index (from 1 to the maximum number of files returned by listlast() function) Examples get5plist(“04”,”2020”,”3”) – get5p_latlon {get5p} Get the latest S5p products (lat long search) Description The function works by searching the latest 10 products available for a specific location (lat long). It allows to download a specific product after identifying it. Usage get5p_latlon(lat, lon, id = NULL) Arguments lat Latitude (degrees) to search at lon Longitude (degrees) to search at id=NULL If the id parameter is omitted, the function returns a list of up to 10 S5p products available at the given coordinates, if an id is specified the functions downloads the product with the indicated id. If id=-1 then all the found products will be downloaded automatically. Examples get5p_latlon(“44”,”12”) get5p_latlon(“44”,”12”,1) — listlast {get5p} List the latest files available in the Coperniucs 5p catalogue Description This function search inside the current catalogue of archived products for the Platform Sentinel 5P (https://scihub.copernicus.eu/catalogueview/S5P/) and returns a list of the archived .csv files of a specific month and year. Usage listlast(month, year) Arguments month Desired month in mm format (April would be “04”, December would be “12”) year Desired year in yyyy format (“2020” not “20”) Examples listlast(“04”,”2020”) — plot5p {get5p} Get a S5p product Description This function allows to inspect a downloaded S5p file or plots it Usage plot5p(fil, variable = NULL) Arguments fil Name of the file to inspect/plot variable If the field is NULL then the function will return a list containing all the informations of the .nc file. Normally the variables names are included as PRODUCT/variable. If the variable name is given as parameter then the function will plot that variable Examples plot5p(“S5P_OFFL_L2__AER_LH_20200527T115918_20200527T134048_13579_01_010302_20200529T045906.nc”) plot5p(“S5P_OFFL_L2__AER_LH_20200527T115918_20200527T134048_13579_01_010302_20200529T045906.nc”,”aerosol_index_340_380”)
