Climaterna: A decade of daily data on births, deaths, pollution and climate variables for all municipalities in Brazil.

This article describes a comprehensive dataset integrating public data from validated sources, including the Mortality Information System (SIM) and the Live Births Information System (SINASC) of DATASUS, the Brazilian Daily Weather Gridded Data (BR-DWGD), and pollution data from the CMIP6 models platform. Additionally, for the state of São Paulo, we incorporated air pollution data from monitoring stations managed by CETESB (Environmental Company of the State of São Paulo). The dataset comprises anonymized microdata on all births and deaths across Brazilian municipalities, with daily granularity from 2010 to 2022. It also includes annual climate (2010 to March 2024) and pollution data (2010 to 2023) for the same geographic scope. This integrated dataset enables diverse analyses exploring the relationships between health and environmental variables, particularly focusing on maternal and neonatal health outcomes in Brazil. By combining data from officially validated sources, this dataset not only supports robust research in demography, population studies, epidemiology, public health, and environmental sciences but also contributes to the democratization of access to information. Data were collected from public databases and processed using RStudio and Python. Climate data (BR-DWG) were produced through statistical corrections and interpolation of measurements from meteorological stations and rain gauges across Brazil.
