Temperature and Dew Point
There is only a single weather station, Aeropuerto Internacional de Crespo, in our network suitable to be used as a proxy for the historical temperature and dew point records of Cartagena.
At a distance of 5 kilometers from Cartagena, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records.
The station records are corrected for the elevation difference between the station and Cartagena according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.
