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. In Fall 2017, CERES FM6 will launch on 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.

We provide accurate data products and information to the public, educators, and scientists.
Energy from the Sun is what provides humans with a climate that allows us to live on Earth. It heats the surface, warms the atmosphere, and powers the ocean currents. CERES instruments allow scientists to get data about this energy balance.
CERES data 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 and S-NPP instruments such as the Moderate Resolution Imaging Spectroradiometer (MODIS) and the Visible and Infrared Sounder (VIRS). Analyses using CERES data, build upon the foundation laid by previous missions such as NASA Langley's Earth Radiation Budget Experiment (ERBE), leading to a better understanding of the role of clouds and the energy cycle in global climate change.
The CERES team provides information about the data and developed a data ordering tool for browsing, subsetting, and ordering the CERES products.

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.

Patrick Taylor from the NASA Langley Science Directorate was at the 21st Session of the Conference of the Parties to the UN Framework Convention on Climate Change (COP21) in Paris. He presented with Dr. John P. Holdren (Assistant to the President for Science and Technology).

Today, the Arctic is changing at a dramatic pace as a result of global warming. Temperatures in the Arctic region are rising at more than twice the average global rate -- altering the lives of its approximately four million inhabitants. The impacts of Arctic climate change have become worse with wider implications, ranging from shifts in atmospheric circulation patterns to acceleration of global sea level rise.
Wherever you are, whoever you are, you are connected to the Arctic region. The Arctic affects our daily weather, our security, the food we eat, and our vast coastlines. As the Arctic continues to warm, dangerous feedback loops come into play. Shorter winters mean an increased prevalence of carbon-releasing wildfires. Warming also promotes thawing of permafrost, soil that remains frozen throughout the year, which could release as much 150 billion tons of carbon into the atmosphere by the end next century – the equivalent of adding 300 million cars to the road. Scientists and global leaders understand the transformations occurring in the Arctic as signs of the global crisis unfolding – one that can only be effectively addressed through international collaboration. This event will discuss the global implications of Arctic climate change and the international approaches needed to adequately address them.

When the mercury thermometer was invented in 1714, it took the scientific world by storm. On his transatlantic crossing in the year 1724, Benjamin Franklin recorded water temperatures by periodically dipping a thermometer into the ocean. By 1850, weather stations across the globe had gleaned a record of air temperatures over land. For the first time, scientists could track Earth’s temperature. And over time, it became clear that temperature was rising.
