INPE/CPTEC The Centro de Previsão de Tempo e Estudos Climáticos (CPTEC) is the operational meteorology and climate research center within the Instituto Nacional de Pesquisas Espaciais (INPE), focused on atmospheric prediction, climate diagnostics, remote sensing, and Earth system modeling. CPTEC bridges applied forecasting services, numerical modeling, and satellite data assimilation to support decision-making across sectors including aviation, agriculture, water resources, and disaster risk management. It interacts with international observatories, academic institutions, and multilateral agencies to advance regional numerical weather prediction and climate projection capabilities.
CPTEC was created in the late 20th century inside INPE to consolidate meteorological prediction and climate research in Brazil, evolving alongside programs such as the Brazilian Space Program and regional initiatives like the Amazon Monitoring Project. Early collaborations involved institutions such as the National Oceanic and Atmospheric Administration, the European Centre for Medium-Range Weather Forecasts, and the World Meteorological Organization, reflecting ties to the United States, France, and the United Kingdom. CPTEC has participated in international field campaigns and networks including the Tropical Rainfall Measuring Mission, the Global Atmosphere Watch, the Southern Hemisphere ADditional OZone Project, and initiatives connected to the Intergovernmental Panel on Climate Change and the United Nations Framework Convention on Climate Change. Over time CPTEC integrated advances from research centers like the Max Planck Institute for Meteorology, the National Aeronautics and Space Administration, the Met Office, and the Centre National de Recherches Météorologiques.
CPTEC operates within INPE's institutional framework alongside divisions that liaise with ministries, state agencies, and academic partners such as the University of São Paulo, the Federal University of Rio de Janeiro, and the Federal University of Amazonas. Governance involves technical committees, scientific councils, and operational units linked to bodies including the Agência Espacial Brasileira, the Brazilian Institute of Environment and Renewable Natural Resources, and sectoral stakeholders like the National Civil Aviation Agency and the Brazilian Navy. Decision-making reflects inputs from international partners such as the World Meteorological Organization, the Group on Earth Observations, the Inter-American Institute for Global Change Research, and regional consortia including Mercosur research networks and Amazon cooperation forums. CPTEC staff engage with professional societies like the American Meteorological Society and the European Geosciences Union.
CPTEC's research portfolio spans atmospheric dynamics, ocean–atmosphere interaction, land surface processes, aerosol–cloud interactions, and climate variability associated with phenomena like El Niño–Southern Oscillation, the Madden–Julian Oscillation, and the South Atlantic Convergence Zone. Services include short-, medium-, and seasonal forecasts, hydrometeorological advisories, agroclimatic advisories for associations such as Embrapa, aviation forecasting for authorities like the International Civil Aviation Organization, and flood risk information for agencies like the National Water Agency. Research collaborations connect CPTEC with laboratories such as the Scripps Institution of Oceanography, the Woods Hole Oceanographic Institution, the National Center for Atmospheric Research, and the Lamont–Doherty Earth Observatory. CPTEC contributes products to platforms used by organizations including the Food and Agriculture Organization, the World Bank, and the World Health Organization.
CPTEC integrates data from satellite missions and ground networks, ingesting measurements from platforms like the GOES, METEOSAT, and Himawari series, the Sentinel satellites, the Aqua and Terra missions carrying MODIS and CERES instruments, and polar-orbiting systems such as NOAA and Suomi NPP. It uses data from radar networks, radiosonde arrays coordinated with national services, ocean buoys from the Tropical Atmosphere Ocean project, and flux towers from FLUXNET sites associated with research centers including INPA and Embrapa. Facilities include supercomputing centers co-located with INPE, observational calibration labs collaborating with institutions like the European Space Agency, the Japan Aerospace Exploration Agency, and the China Meteorological Administration. CPTEC also leverages data from the Global Precipitation Measurement mission, the Tropical Rainfall Measuring Mission, and ground campaigns tied to universities like the Federal University of Ceará.
CPTEC develops and operates atmospheric models, data assimilation systems, and coupled ocean–atmosphere configurations informed by academic groups such as the Geophysical Fluid Dynamics Laboratory, the Centre National de Recherches Météorologiques, and the European Centre for Medium-Range Weather Forecasts. Its model suite includes limited-area and global models, regional climate downscaling frameworks using approaches adopted by the Coordinated Regional Climate Downscaling Experiment, and seasonal prediction systems linked to the Predictability Project and the Coupled Model Intercomparison Project. High-performance computing resources support ensemble forecasting, reanalysis projects comparable to ERA and MERRA, and studies involving parameterizations from research programs at Princeton University, the University of Reading, and the Massachusetts Institute of Technology. CPTEC contributes to operational forecast exchanges with services such as the Met Office, MeteoFrance, the National Weather Service, and the Japan Meteorological Agency.
CPTEC engages in graduate training, internships, and capacity-building workshops with universities and institutes including the National Institute for Space Research, the Brazilian Academy of Sciences, the International Centre for Theoretical Physics, and regional training centers sponsored by UNESCO and the World Meteorological Organization. Outreach activities target stakeholders such as municipal civil defense agencies, agricultural cooperatives, and aviation operators, and involve partnerships with NGOs, the Red Cross, and development agencies. Collaborative research extends to multinational projects with institutions like Columbia University, the University of Oxford, the University of California system, and research networks including CLARIS, PANGEA, and the Amazon Cooperation Treaty Organization.
Notable CPTEC contributions include operationalizing regional numerical weather prediction for South America, advancing coupled seasonal forecast products used in policy decisions, and providing satellite-based deforestation and fire monitoring services that complement programs by the Brazilian Institute of Environment and Renewable Natural Resources, the National Institute for Space Research satellite programs, and the Global Forest Watch network. CPTEC has supported international field experiments, contributed to IPCC assessment reports, and collaborated on satellite mission science teams from NASA, ESA, JAXA, and ISRO. Achievements include improvements in flood forecasting used by the National Water Agency, agroclimatic advisories adopted by Embrapa, and peer-reviewed advances in understanding South Atlantic climate dynamics published with coauthors from institutions such as the Max Planck Institute, the University of Buenos Aires, and the University of Cape Town.
