This paper presents three datasets of anomalies of oceanic physical parameters and surface atmospheric fluxes in the northeast region of Brazil, geographically limited by 42.5°W - 29.75°W / 20.5°S - 1.25°N, calculated from the SODA, TROPFLUX and GPCP datasets. The DASAF-BNE (Daily Anomalies of the Surface Atmospheric Fluxes of the Brazilian Northeast), DRA-BNE (Daily Rainfall Anomalies in the Brazilian Northeast), and MAOP-BNE (Monthly Anomalies of Oceanographic Parameters in the Brazilian Northeast) datasets are generated with 0.25° resolution bilinearly interpolating the original datasets. This database includes four files in NetCDF format, which facilitates its handling due to the diversity of freeware tools that exist, DASAF-BNE and DRA-BNE have a daily frequency, while MAOP-BNE has a monthly frequency. This database is mainly intended to research climate changes in the Brazilian Northeast.
