Who are we?
For more than 30 years, the Science Directorate at NASA's Langley Research Center has shaped how scientists measure Earth's incoming and outgoing energy. The CERES Science, Data Management, Data Processing and Stewardship Teams are devoted to providing valuable Earth Radiation Budget data to the science community. The CERES experiment is one of the highest priority scientific satellite instruments developed for NASA's Earth Observing System (EOS). The first CERES instrument was launched in December of 1997 aboard NASA's Tropical Rainfall Measurement Mission (TRMM), CERES instruments are collecting observations on three separate satellite missions, including the EOS Terra and Aqua observatories, the Suomi National Polar-orbiting Partnership (S-NPP) observatory, and soon, the Joint Polar Satellite System, a partnership between NASA and NOAA. CERES FM6 launched on November 18, 2017 aboard JPSS-1, becoming the last in a generation of successful CERES instruments that help us to better observe and study Earth's interconnected natural systems with long-term data records.

The Earth and its interconnected systems have always been a fascination for Norman Loeb.
As the principal investigator of NASA's Radiaton Budget Science Project, Loeb oversees a series of space-borne instruments that measure reflected sunlight and thermal radiation emitted by the Earth. It gives him a chance to satisfy his curiosity about our home planet from NASA's Langley Research Center in Hampton, Virginia.

The CERES team announces the release of the Edition4A SYN1deg data product suite. This includes TOA, surface and atmospheric radiative fluxes and cloud, aerosol and surface properties at 1x1 deg regional, 1 deg zonal and global spatial resolutions, and the following temporal resolutions: hourly (SYN1deg-1Hour), 3-hourly (SYN1deg-3Hour), daily (SYN1deg-Day), monthly (SYN1deg-Month) and monthly in hourly increments (SYN1deg-MHour).
Edition4A SYN1deg products leverage off of algorithm improvements included in the Edition4 suite of CERES levels 1 & 2 data products. Edition4A SYN1deg products are processed using consistent atmospheric reanalysis data and include hourly resolution radiative fluxes and derived cloud properties.
For variable-level subsetting, data may be ordered via the CERES Ordering Tool:
This initial release covers the period March 2000 - January 2017. Additional months will become available as they are processed.
Release of Level 3 Edition4 TOA Radiation Budget dataset from ERBS WFOV Nonscanner Observations
The ERBE team announces the release of Level 3 Edition4 top-of-atmosphere (TOA) irradiance data products from Earth Radiation Budget Satellite (ERBS) wide-field-of-view (WFOV) nonscanner observations. The Edition4 dataset is available from January 1985 to December 1998. This task is made possible by the NASA Making Earth Science Data Records for Use in Research Environments (MEaSUREs) program. NASA has been making concerted efforts to observe the Earth radiation budget (ERB) since 1984 through two projects: Earth Radiation Budget Experiment (ERBE) and Clouds and the Earth's Radiant Energy System (CERES). However, the past ERB dataset from ERBS has shown higher uncertainties in the later period and is not at the same radiometric scale as CERES. The recently released new Edition4 dataset uses improved algorithms to reprocess ERBS WFOV nonscanner observations based on lesson learned from CERES. In addition, these datasets are calibrated with CERES-derived irradiances and the spatial coverage is extended to global from 60N to 60S latitudes. The release of Edition4 ERBS datasets combined with that provided by CERES generates a long-term consistent TOA radiation budget, that spans nearly 30 years to date.
The dataset is distributed by NASA Langley Atmospheric Science Data Center (ASDC) and is available at https://eosweb.larc.nasa.gov/project/measures/long-term-toa-m
The CERES team announces the release of Edition 4.0 of the Energy Balanced and Filled (EBAF) Suface data product. EBAF-Surface Ed4.0 leverages off of the many algorithm improvements that have been made in the Edition 4 suite of CERES level 1-3 data products. Surface fluxes included in Ed4 EBAF-Surface are consistent with top-of-atmosphere fluxes included in the Ed4 EBAF-TOA data product that was released earlier this year.
This initial release covers the period March 2000 - February 2016. Additional months will become available as they are processed.

Earth’s energy budget. Not a familiar concept? Maybe you’re scratching your head, wondering, what is that? Don’t worry. You’re not the only one.
The good news is: We have answers. And those answers come courtesy of Norman Loeb, an atmospheric scientist at NASA’s Langley Research Center in Hampton, Virginia. Loeb is the principal investigator for an experiment called the Clouds and the Earth’s Radiant Energy System (CERES). CERES instruments measure how much of the sun’s energy is reflected back to space and how much thermal energy is emitted by Earth to space. Five CERES instruments are on orbit aboard three satellites, and the CERES team at Langley is preparing to launch a sixth CERES instrument, CERES FM6, to orbit later this year.
We recently sent Loeb a few questions about the energy budget. View the article to see his responses.

A new study suggests that most global climate models may underestimate the amount of rain that will fall in Earth's tropical regions as our planet continues to warm. That's because these models underestimate decreases in high clouds over the tropics seen in recent NASA observations, according to research led by scientist Hui Su of NASA's Jet Propulsion Laboratory in Pasadena, California.

It will join five other CERES instruments on orbit. CERES monitors a variety of cloud properties, prevalence, altitude, thickness, and the size of cloud particles.
The Clouds and the Earth's Radiant Energy System (CERES) experiment is one of the highest priority scientific satellite instruments developed for NASA's Earth Observing System.
CERES products include both solar-reflected and Earth-emitted radiation from the top of the atmosphere to the Earth's surface. Cloud properties are determined using simultaneous measurements by other EOS instruments.

The Clouds and the Earth’s Radiant Energy System (CERES) team released Edition 4.0 of the Energy Balanced and Filled (EBAF) Top-of-Atmosphere (TOA) data product. EBAF-TOA Ed4.0 leverages off of the many algorithm improvements that have been made in the Edition 4 suite of CERES level 1-3 data products. EBAF-TOA Ed4.0 also includes a limited set of MODIS imager-based cloud parameters alongside the EBAF-TOA fluxes.
