Data_Sheet_1_Intraseasonal Drivers of the 2018 Drought Over São Paulo, Brazil.PDF
Dry conditions occurred over São Paulo state (southeastern Brazil) from February to July 2018, causing the driest semester in 35 years. Socioeconomic impacts included a record number of fire spots, most adverse conditions to pollutant dispersion in 3 years and the winter's lowest water reservoi...
