repository
reader script

New aerocom variable

Add a new entry to pyaerocom/data/variables.ini

[concch]
description=Mass concentration of CH above ambient level
unit = ng m-3

Convert from DataFrame to UngriddedData

Split DataFrame into one series per site and wrap into dictionary containing keys needed to create a pyaerocom.metastandards.StationMetaData object

def read_etex1() -> UngriddedData:
    def reader() -> Generator[dict]:
        station = read_stations().set_index("cc")
        for cc, df in read_data().groupby("cc"):
            site = station.loc[cc]
            conc = df.rename(columns={"end": "time"}).set_index("time").concentration
            conc.name = "concch"
            yield dict(
                station_id=site.name,
                station_name=site["Station name"],
                latitude=site.Long,
                longitude=site.Lat,
                altitude=site.Alt,
                concch=conc,
                var_info=dict(concch=dict(units=ETEX1.units, ts_type="3hourly")),
            )


    return UngriddedData.from_station_data(list(reader()))
