Over the past 18 months and despite the challenges of a global pandemic, the Earth Observing Systems XXV conference was successfully held in August 2020; and Earth observing missions continued to be launched and/or developed. For example, missions recently launched and commissioned include the Indian Space Research Organization (ISRO) RISAT 2BR-1 mission launched on December 11, 2019 and Cartosat-3 launched on November 27, 2019, the Canadian Space Agency (CSA) RADARSAT mission on June 12, 2019, and the Korean Aerospace Research Institute (KARI) Geostationary Environmental Monitoring Spectrometer (GEMS) on February 18, 2020. An impressive number of missions are under development and being readied for launch in the next 2 to 3 years. These include the National Oceanic and Atmospheric Administration/National Aeronautics and Space Administration (NOAA/NASA) Joint Polar Satellite System-2 (JPSS-2) in 2022, the NOAA/NASA Geostationary Operational Environmental Satellite-T (GOES-T) in 2021, NASA’s Tropospheric Emissions: Monitoring of Pollution (TEMPO) in 2022, the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission in 2023, the GeoCARB mission in 2022, and Landsat-9 in 2021. The European Space Agency (ESA) is also preparing an impressive number of missions for launch, including the two Earth Explorer missions, the Biomass and the Fluorescence Explorer (FLEX), slated for launch in 2022, and the Sentinel 5 mission which will launch on the Meteosat Second Generation A satellite and Sentinel 4A mission which will launch on the Meteosat Third Generation Satellite-S slated for launch in 2021. The China Meteorological Administration (CMA) continues to develop and launch its Feng Yun-3 (FY-3) and Feng Yun-4 (FY4) missions.

A number of joint, international missions are also under development. These include the joint ESA, European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), NASA, NOAA and Centre National d'études Spatiales (CNES) Copernicus Sentinel-6 Michael Freilich mission to be launched in November 2020, the joint, ESA/Japan Aerospace Exploration Agency (JAXA) Earth, Cloud, Aerosol, and Radiation Explorer to be launched in 2022, and the joint NASA, CNES, CSA, and UK Space Agency Surface Water Ocean Topography (SWOT) mission to be launched in 2021.

On an international scale, these missions have or will join the already impressive number of Earth observing satellite systems currently operating on-orbit with active and passive instruments producing remote sensing data—from the ultraviolet through the radar/microwave wavelength region. This proliferation of satellite instruments requires calibration and validation of the quality of the data they produce through a combination of careful pre-launch testing, on-orbit monitoring, and on-orbit inter-instrument comparisons of measurements made by other on-orbit assets and by airborne, balloon-borne, and ground-based remote sensing instrumentation.

Advances in electro-optic technologies and data acquisition and analysis techniques by commercial, academic, and governmental research institutions have promoted the successful on-orbit operation of hyperspectral Earth remote sensing instruments and enabled the development of lower-cost, miniature satellite sensors with specific areas of performance equal to or better than those of traditional systems.

Lastly, space agencies continue to formulate and/or refine their long-term mission plans. For example, the 2017-2027 U.S. National Research Council's Decadal Survey on Earth Science and Applications from Space continues to serve as the guide for the science and application objectives of future US space-based observations of Earth in terms of instruments and missions. NASA continues its development of its Earth Venture missions. ESA and EUMETSAT continue instrument formulation and launch planning for their future Earth Explorers, follow-on Copernicus Sentinel Missions, Meteosat Third Generation (MTG), and EUMETSAT Polar System-Second Generation (EPS-SG) programs.

In summary, the Earth Observing Systems XXV conference welcomes the submission of papers over a wide range of remote sensing topics. Papers are solicited in the following general areas:
  • Earth-observing mission studies including new system requirements and plans
  • commercial system designs
  • electro-optical sensor designs and sensitivity studies
  • ultraviolet through thermal infrared, microwave, radar, and lidar remote sensing systems
  • hyperspectral remote sensing instruments and methodologies
  • instrument sub-system and system level pre-launch and on-orbit calibration and characterization
  • vicarious calibration techniques and results
  • satellite instrument airborne simulators
  • techniques for enhancing data processing, reprocessing, archival, dissemination, and utilization
  • conversion from research to operational systems
  • on-orbit instrument inter-comparison techniques and results
  • enabling technologies (optics, antennas, electronics, calibration techniques, detectors, and models)
  • sensor calibration traceability, uncertainty, and pre-launch to on-orbit performance assessments
  • lunar radiometry and photometry
  • remote sensing data acquisition and analysis.
