Data is imported from   https://alerta.ina.gob.ar/pub/mapa. Example query:

https://alerta.ina.gob.ar/pub/datos/datos&timeStart=2019-06-27&timeEnd=2019-07-03&siteCode=156&varId=2&format=json

Time start and time end are from the period defined in the configuration file. SiteCode is the (external) location id, varId is the  (external) parameter id.
