The National Climate Assessment (NCA) is a United States government interagency ongoing effort on climate change science conducted under the auspices of the Global Change Research Act of 1990. The NCA is a major product of the U.S. Global Change Research Program (USGCRP) which coordinates a team of experts and receives input from a Federal Advisory Committee. NCA research is integrated and summarized in the mandatory ongoing National Climate Assessment Reports. The reports are "extensively reviewed by the public and experts, including federal agencies and a panel of the National Academy of Sciences. For the Third National Climate Assessment, released in 2014, USGCRP coordinated hundreds of experts and received advice from a sixty-member Federal Advisory Committee. The Fourth NCA (NCA4) was released in two volumes, in October 2017 and in November 2018.
The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. It is a joint NASA / USGS program. On 23 July 1972, the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat 1 in 1975. The most recent, Landsat 9, was launched on 27 September 2021.
The Earth Observing System (EOS) is a program of NASA comprising a series of artificial satellite missions and scientific instruments in Earth orbit designed for long-term global observations of the land surface, biosphere, atmosphere, and oceans. Since the early 1970s, NASA has been developing its Earth Observing System, launching a series of Landsat satellites in the decade. Some of the first included passive microwave imaging in 1972 through the Nimbus 5 satellite. Following the launch of various satellite missions, the conception of the program began in the late 1980s and expanded rapidly through the 1990s. Since the inception of the program, it has continued to develop, including; land, sea, radiation and atmosphere. Collected in a system known as EOSDIS, NASA uses this data in order to study the progression and changes in the biosphere of Earth. The main focus of this data collection surrounds climatic science. The program is the centrepiece of NASA's Earth Science Enterprise.
The National Snow and Ice Data Center (NSIDC) is a United States information and referral center in support of polar and cryospheric research.

The Earth System Modeling Framework (ESMF) is open-source software for building climate, numerical weather prediction, data assimilation, and other Earth science software applications. These applications are computationally demanding and usually run on supercomputers. The ESMF is considered a technical layer, integrated into a sophisticated common modeling infrastructure for interoperability. Other aspects of interoperability and shared infrastructure include: common experimental protocols, common analytic methods, common documentation standards for data and data provenance, shared workflow, and shared model components.
The Earth Observing System Data and Information System (EOSDIS) is a key core capability in NASA’s Earth Science Data Systems Program. Designed and maintained by Raytheon Intelligence & Space, it is a comprehensive data and information system designed to perform a wide variety of functions in support of a heterogeneous national and international user community.
Geospatial metadata is a type of metadata applicable to geographic data and information. Such objects may be stored in a geographic information system (GIS) or may simply be documents, data-sets, images or other objects, services, or related items that exist in some other native environment but whose features may be appropriate to describe in a (geographic) metadata catalog.
The Global Change Master Directory holds more than 28,000 data set descriptions, known as DIFs. This format is compatible with the Federal Geographic Data Committee's (FGDC) standard and the international ISO 19115 standard. The purpose of the directory is to provide users with information on the availability of data and services that will meet their needs, along with efficient access to those data and services. Links are provided, when available, to connect directly to the data or services of interest.
The Environmental Science Services Administration (ESSA) was a United States Federal executive agency created in 1965 as part of a reorganization of the United States Department of Commerce. Its mission was to unify and oversee the meteorological, climatological, hydrographic, and geodetic operations of the United States. It operated until 1970, when it was replaced by the new National Oceanic and Atmospheric Administration (NOAA).
Computational geophysics is the field of study that uses any type of numerical computations to generate and analyze models of complex geophysical systems. It can be considered an extension, or sub-field, of both computational physics and geophysics. In recent years, computational power, data availability, and modelling capabilities have all improved exponentially, making computational geophysics a more populated discipline. Due to the large computational size of many geophysical problems, high-performance computing can be required to handle analysis. Modeling applications of computational geophysics include atmospheric modelling, oceanic modelling, general circulation models, and geological modelling. In addition to modelling, some problems in remote sensing fall within the scope of computational geophysics such as tomography, inverse problems, and 3D reconstruction.
The Earth Observing System (EOS) Clearinghouse, or ECHO refers to a system that was used by the National Aeronautics and Space Administration (NASA) to spatially, temporally and otherwise index the petabytes of data that NASA's Earth Science projects collect. It does not hold the data itself, but serves as a search engine that other applications can access via a web service based interface. While ECHO has been set up to support both data and services, as of mid-2008, data is well represented and services are yet to be focused on.
The United States Global Change Research Program (USGCRP) coordinates and integrates federal research on changes in the global environment and their implications for society. The program began as a presidential initiative in 1989 and was codified by Congress through the Global Change Research Act of 1990, which called for "a comprehensive and integrated United States research program which will assist the Nation and the world to understand, assess, predict, and respond to human-induced and natural processes of global change."
DataONE is a network of interoperable data repositories facilitating data sharing, data discovery, and open science.
