CERES

CERES is a NASA series of Earth-observing radiometers designed to measure reflected solar radiation and emitted thermal radiation to quantify the Earth's radiative energy budget. Developed within programs involving Langley Research Center, Jet Propulsion Laboratory, University of Wisconsin–Madison, and industrial partners like Northrop Grumman and Ball Aerospace, CERES instruments have flown on missions associated with Tropical Rainfall Measuring Mission, Aqua (satellite), Suomi NPP, and NPOESS Preparatory Project. The program links to climate initiatives involving Intergovernmental Panel on Climate Change, National Oceanic and Atmospheric Administration, and international satellite collaborations such as European Space Agency missions.

Overview

CERES instruments provide broadband shortwave and longwave radiometric measurements to estimate top-of-atmosphere, surface, and atmosphere radiative fluxes. CERES products support research by teams at NASA Goddard Space Flight Center, Goddard Institute for Space Studies, University of Maryland, Columbia University, Massachusetts Institute of Technology, and other institutions. The mission contributes to assessments by IPCC, informs modeling activities at National Center for Atmospheric Research, and complements observations from CloudSat, CALIPSO, Aqua (satellite), and MODIS. CERES data underpin studies connected to policies from entities like the United States Department of Energy and European Commission research frameworks.

CERES traces conceptual roots to radiometry efforts at Langley Research Center and heritage instruments such as those on the Nimbus program and Earth Radiation Budget Experiment. Formal development involved collaborations among NASA, NOAA, United States Geological Survey, and academic groups including University of Wisconsin–Madison and Texas A&M University. Program milestones align with launches of platforms like TRMM, Aqua (satellite), and Suomi NPP, and with policy milestones such as reports from the National Academies of Sciences, Engineering, and Medicine. Key engineering and management participants have included teams from Northrop Grumman, Raytheon, Ball Aerospace, and contractors who worked with Langley Research Center. CERES progressed alongside international projects like ERS-1, Envisat, and Meteosat series.

Each CERES instrument uses thermistor bolometers and wavelength-selective optics to sample broadband solar and terrestrial fluxes. Design work drew on heritage from ERBE instruments and iterative improvements based on validation campaigns with facilities at NASA Goddard Space Flight Center and field sites run by ARM Climate Research Facility and NOAA's Earth System Research Laboratories. Calibration strategies have involved cross-comparisons with sensors on Aqua (satellite), Suomi NPP, and intercalibration efforts with European Space Agency radiometers. Engineering analyses were performed by teams at Jet Propulsion Laboratory and Langley Research Center, while algorithm development engaged researchers at University of Wisconsin–Madison, Colorado State University, and University of Colorado Boulder.

CERES mission operations utilize ground systems at centers such as NASA Goddard Space Flight Center and data centers like the Langley Atmospheric Science Data Center. Data products include top-of-atmosphere fluxes, surface flux estimates, and cloud property retrievals that interface with model output from NCAR Community Earth System Model, NOAA Global Forecast System, and assimilation systems at European Centre for Medium-Range Weather Forecasts. Product suites have been distributed to researchers at California Institute of Technology, Princeton University, Harvard University, and international partners such as Japan Aerospace Exploration Agency and China National Space Administration. Validation and field campaign coordination involved groups like ARM, Microwave Radiometer Network, and observatories including Punta Arenas Observatory and Mauna Loa Observatory.

CERES observations have quantified spatial and temporal patterns in Earth's energy imbalance, influenced studies at IPCC, and provided constraints used by NASA Goddard Institute for Space Studies and Scripps Institution of Oceanography for climate trend analysis. Results have been incorporated into assessments by National Oceanic and Atmospheric Administration, informed attribution studies involving researchers at Lawrence Berkeley National Laboratory and Pacific Northwest National Laboratory, and supported investigations into cloud radiative effects led by teams at University of Oxford, University of Reading, and University of Cambridge. CERES data have contributed to policy-relevant metrics used by agencies like the United States Environmental Protection Agency and international bodies including United Nations Framework Convention on Climate Change.

Funding and collaboration for CERES have involved NASA, NOAA, cooperative agreements with universities including University of Wisconsin–Madison and University of Colorado Boulder, and partnerships with industry contractors such as Northrop Grumman and Ball Aerospace. International scientific collaboration has engaged European Space Agency, Japan Aerospace Exploration Agency, Canadian Space Agency, and researchers from institutions like Peking University, Indian Space Research Organisation, Australian National University, and Max Planck Institute for Meteorology. Program governance and reviews have involved panels from the National Academies of Sciences, Engineering, and Medicine and advisory interactions with policy entities such as the Office of Science and Technology Policy.
