The Earth Observation Assessment (EOA) is a Congressionally-directed periodic evaluation of the nation's civil Earth observation portfolio. This portfolio comprises both remote and in-situ sensors, operated by both the public and the private sector. The Earth Observation Assessment measures the effectiveness of the civil Earth observation system in meeting federal government objectives identified as Societal Benefit Areas (SBA). The White House Office of Science and Technology Policy (OSTP) charters the U.S. Group on Earth Observations (USGEO) as a subcommittee of the National Science and Technology Council (NSTC) Committee on Environment. USGEO conducts the Earth Observation Assessment to inform the regularly-updated National Plan for Civil Earth Observations, which serves to coordinate the development and support of the Earth observation enterprise across all sectors. This is the data that supports the EOA 2023 Tableau Dashboard on the USGEO website.

'The Earth Observing-1(EO-1) satellite was launched on November 21, 2000 by the U.S. Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA) as a one-year technology demonstration mission to evaluate the performance of advanced capabilities for future space missions. The EO-1 mission validated highly integrated multispectral data from the Advanced Land Imager (ALI) sensor and hyperspectral imaging data from the Hyperion sensor. After the initial technology mission was accomplished, NASA and the USGS agreed to continue the EO-1 program due to high interest in the specialized data from scientific communities. EO-1 Data products consist of imagery collected during the original one-year mission, as well as more recent Data Acquisition Requests (DARs) from the EO-1 Extended Mission. EO-1 scenes are processed to Level 1Gst (L1Gst) and images with adequate ground control points are processed to Level 1T (L1T). L1Gst and L1T products are provided in GeoTIFF format. Scenes that have been processed to L1T are also available as Full Resolution Browse and GIS Ready Bundle products in JPEG format. Level 1R (L1R) products in HDF format are only available for Hyperion data. '

Advanced Land Imager (ALI) provides image data from ten spectral bands (band designations). The instrument operates in a pushbroom fashion, with a spatial resolution of 30 meters for the multispectral bands and 10 meters for the panchromatic band. The standard scene width is 37 kilometers. Standard scene length is 42 kilometers, with an optional increased scene length of 185 kilometers (additional information). For Advanced Land Imager (ALI) data, the following levels of correction are available: Level 1R radiometrically corrected with no geometric correction applied. The image data are provided in 16-bit radiance values. The data are available in Hierarchical Data Format (HDF) and are distributed on CD-ROM, DVD, and File Transfer Protocol (FTP). Level 1Gs is geometrically corrected and will be provided as a single "stitched" file. The image data are provided in 16-bit radiance values. The data are available in Hierarchical Data Format (HDF) or Geographic Tagged Image-File Format (GeoTIFF) and are distributed on DVD and File Transfer Protocol (FTP). Level 1Gst is terrain corrected and will be provided as a single "stitched" file. The image data are provided in 16-bit radiance values. The data are available in Hierarchical Data Format (HDF) or Geographic Tagged Image-File Format (GeoTIFF) and are distributed on DVD and File Transfer Protocol (FTP). [Source: USGS/EDC Homepage]

This dataset contains calibrated, 1.05- to 4.8-micron spectra of Earth acquired by the High Resolution Infrared Spectrometer (HRII) during the EPOCh and Cruise 2 phases of the EPOXI mission. Five sets of observations were acquired on 18-19 March, 28-29 May and 04-05 June 2008 and on 27-28 March and 04-05 October 2009 to characterize Earth as an analog for extrasolar planets. Each observing period lasted approximately 24 hours, and spectra were acquired twice every 2 hours. During the observing period in May 2008, the Moon transited across Earth as seen from the spacecraft. HRII spectra were not acquired during the first attempt of an Earth south polar observation on 27-28 September 2009 because fault protection turned that instrument off; the full sequence was successfully rerun on 04-05 October 2009. Version 2 corrects an error in the IR absolute calibration that previously inflated all spectra by a factor of 2.

The Global Surface Emissivity Spectral Atlas (GSESA) database contains global, monthly climatology infrared emissivity functional Empirical Orthogonal Function (EOF) scores in 0.25 x 0.25 latitude-longitude resolution. An eigenvector file and a reader file allow customers to produce emissivity spectra. The emissivity functional EOF scores were developed using the Infrared Atmospheric Sounding Interferometer (IASI) instrument on the METOP-A, METOP-B, and METOP-C satellites for the period 2007-07-01 to 2025-01-31. An inversion scheme, dealing with cloudy as well as cloud-free radiances observed with ultraspectral infrared (IR) sounders, was developed to simultaneously retrieve atmospheric thermodynamic and surface or cloud microphysical parameters. This inversion scheme was applied to the IASI instrument. Rapidly produced surface spectral emissivity (SSE) is initially evaluated through quality control checks on the retrievals of other impacted surface and atmospheric parameters. The GSESA data are provided in binary format, with sample reader files that can be used in a Fortan IDE to read a functional emissivity EOF compressed file (e.g., MFEMI_MONTH01_A_V5P.bin) and its EOF eigenvector file (IASI_B_EV_FUNC_GLOBAL_V4.bin) to produce spectral emissivity at a certain location (latitude and longitude). A sample reader file can be used in a Matlab IDE is also provided. These data were created with funding from the NASA Internal Scientist Funding Model for the National Airborne Sounder Testbed-Interferometer (NAST-I).
