Atmospheric Science Data Center (ASDC)

The Radiation Budget Science Project (RBSP)/CERES Science Team announces the release of Edition 4.2 of the CERES Energy Balanced and Filled (EBAF) data product. EBAF 4.2 seamlessly combines CERES observations from Terra for March 2000 to June 2002, Terra and Aqua for July 2002 to March 2022, and NOAA-20 for April 2022 onwards. Algorithm improvements and corrections to both TOA and surface fluxes are included in EBAF Edition 4.2.

This initial release of combined TOA and surface fluxes and cloud properties covers the period March 2000 – March 2022. A stand-alone version of TOA fluxes and cloud properties is current through November 2022. Additional months will become available as they are processed.

This edition follows the 2019 release of EBAF Edition 4.1.

Information about this new data product, including data availability, user documentation, quality statements, relevant links, tools for working with the data, etc. can be found at the following Atmospheric Science Data Center (ASDC) links:

The Atmospheric Science Data Center (ASDC) has released data for the Arctic Research of the Composition of the Troposphere from Aircraft & Satellites (ARCTAS) campaign. ARCTAS was a field campaign that explored environmental processes related to a high degree of climate sensitivity in the Arctic. The campaign was part of NASA’s contribution to the International Global Atmospheric Chemistry (IGAC) Polar Study using Aircraft, Remote Sensing, Surface Measurements, and Models of Climate, Chemistry, Aerosols, and Transport (POLARCAT) Experiment for the International Polar Year 2007-2008. ARCTAS consisted of two, three-week aircraft deployments conducted in April and July 2008. Three NASA aircrafts, the DC-8, P-3B, and BE-200, conducted measurements and were equipped with suites of in-situ and remote sensing instrumentation. Airborne data was used in conjunction with satellite observations from AURA, AQUA, CloudSat, PARASOL, CALIPSO, and MISR.

The ASDC houses the ARCTAS aircraft data, along with data relating to MISR and CALIPSO.

Additional information can be found on the ARCTAS Landing Page.

November 2022

The Aerosol Cloud meTeorology Interactions oVer the western ATlantic Experiment (ACTIVATE) team hosted an open data workshop on November 7, 2022 for anyone interested in learning how to access and visualize airborne data. This workshop went over the progress of the ACTIVATE campaign to date, as well as diving into some of the measurement techniques and data archival processes. The workshop featured talks by all groups associated with the science team to discuss status and applications associated with instrument and modeling datasets. The webinar aimed to motivate the ongoing studies of aerosol-cloud interactions and the importance of airborne measurements.

September 2022

The Aerosol Cloud meTeorology Interactions oVer the western ATlantic Experiment (ACTIVATE) team led an open data workshop webinar hosted by the National Association of Geoscience Teachers (NAGT) for anyone interested to learn how to access and visualize airborne data. This webinar went over the science motivation of ACTIVATE, as well as included activities to expose participants to Python. The webinar aimed to motivate the study of aerosol-cloud interactions and the importance of airborne measurements as well as use the Google Colaboratory (Google Colab) environment to examine atmospheric properties derived from both in situ and remote sensing products.

July 2022

The Aerosol Cloud meTeorology Interactions oVer the western ATlantic Experiment (ACTIVATE) team hosted a free open data workshop webinar series for anyone interested to learn how to use the airborne data and to promote dialogue about data analysis ideas and collaborative projects in the area of aerosol-cloud-meteorology interactions. This particular session trained interested attendees to use a Google Colaboratory (i.e., Google Colab) environment for data visualization and to examine atmospheric properties derived from both in situ and remote sensing products.

October 2021

The ACTIVATE team hosted an open data workshop with over 70 participants over a two-day period from October 20-21, 2021. The purpose of this workshop was to introduce the ACTIVATE project to a larger, international, pool of atmospheric sciences and applications communities. The first day of the workshop covered how to access and utilize ACTIVATE data, a case study on ACTIVATE Research Flight 12 – a statistical survey flight, and ended with a discussion on using data. Day two began with the second case study on Research Flights 13 and 14 – both of which were process study flights – and ended with a continuation on the discussion from the previous day.
