A mirror dataset designed for hydrometeorological time series analysis in Brazil

A mirror dataset This dataset is a mirror of official data released by Brazil's Hydrometeorological public services. However, the dataset here is streamlined for processing and managing large volumes of data. Data availabe Hourly time series of automatic weather stations Available files: inmet_autoh_db.parquet -- database with time series of INMET automatic hourly stations; inmet_autoh_catalog.csv -- catalog of INMET automatic hourly stations; inmet_autoh_glossary.csv -- glossary of catalog and database of INMET automatic hourly stations; Time range sampled: from 2000-01-01 to 2024-12-31 Meteorological variables: p - Total hourly precipitation (mm); pa_loc - Atmospheric pressure at the station level - hourly (MB); rad - Global radiation (kJ/m²) temp_db - Dry bulb hourly air temperature (°C); temp_dp - Dew point temperature (°C); rm - Relative hourly air moisture (%) wd - Wind - hourly direction (°); wg - Wind - maximal gust speed (m/s); ws - Wind - hourly speed (m/s); Data was retrieved from: INMET (2025). Meteorological Database for Education and Research (BDMEP) from National Institute of Meteorology (Instituto Nacional de Meteorologia - INMET). Available at: https://bdmep.inmet.gov.br/ Latest access: February of 2025. Daily time series of conventional weather stations Available files: inmet_convd_db.parquet -- database with time series of INMET conventional daily stations; inmet_convd_catalog.csv -- catalog of INMET conventional daily stations; inmet_convd_glossary.csv -- glossary of catalog and database of INMET conventional daily stations; Time range sampled: from 1961-01-01 to 2024-12-31 Meteorological variables: p - Total precipitation - daily (mm); evp - Piché evaporation - daily (mm); ist - Total sunshine - daily (h); temp_max - Maximum temperature - daily (°C); temp_mean - Compensated average temperature - daily (°C); temp_min - Minimum temperature - daily (°C); rm_mean - Relative air humidity - daily average (%); rm_min - Relative air humidity - daily minimum (%); ws_mean - Wind - daily average speed (m/s); Data was retrieved from: INMET (2025).
