The 2018-2020 CEOS Work Plan
April 2019
CEOS recently updated our new 3-year work plan, covering the period 2019-2021. This CEOS Work Plan describes what we, through the efforts of our 62 Members & Associates, will deliver over the next three years to enhance the availability and use of satellite Earth observations.

A Layman’s Interpretation Guide to L-band and C-band Synthetic Aperture Radar Data
November 2018
This “layman’s” guide was developed to provide users who have little or no experience with spaceborne Synthetic Aperture Radar (SAR) data with a simple reference document that outlines some basic concepts of radar remote sensing, presents some commonly used SAR datasets, and provides some examples of how a few different land cover types may appear in SAR imagery. This document was developed under funding from the CEOS Systems Engineering Office (SEO).

Feasibility Study for an Aquatic Ecosystem Earth Observing System
April 2018
This Study was prepared in response to action C.10 of the CEOS Water Strategy, and three activities are defined in it: An assessment of the benefits and technological difficulties of designing a global satellite mission focused on inland, estuarine, deltaic, and near coastal waters; An examination of the threshold and baseline observation requirements for sensors suitable for aquatic ecosystems; A GEO Water community definition for inland and near-coastal water quality and benthic habitat essential variables.

Special 2018 Edition Earth Observation Handbook: Satellite Earth Observations in Support of the Sustainable Development Goals
March 2018
The Earth Observation Handbook 2018 Special Edition March, 2018 2030 Agenda for Sustainable Development and the Sustainable Development Goals, Special 2018 Edition Earth Observation Handbook on Sustainable Development Goals, Special 2018 Edition This new 2018 Special Edition of the EO Handbook – Satellite Earth Observations in Support of the Sustainable Development Goals – is the 3 rd thematic EO Handbook (preceded by the EO Handbooks on Disaster Risk Reduction and Climate). Coordinated by ESA on behalf of the CEOS Ad Hoc Team on SDGs, with valuable contributions from Symbios Spazio, the GEO Initiative on SDGs (EO4SDG), and the United Nations Committee of Experts on Global Geospatial Information Management (UN-GGIM), this 100-page Handbook promotes and showcases the contribution of Earth observations to the realization of the 2030 Agenda on Sustainable Development, its goals and targets, and to the SDG Global Indicator Framework.

Land Surface Temperature Product Validation Best Practice Protocol
October 2017
This document expresses the views of the land surface temperature (LST) and emissivity focus area of the Committee on Earth Observation Satellites (CEOS) Working Group on Calibration and Validation (WGCV) Land Product Validation (LPV) subgroup. This focus area provides those involved in the production and validation satellite-based LST products with a forum for documenting accepted best practices in an open and transparent manner. The LST product validation best practice protocol document (V1.0) presented here has undergone scientific review by remote sensing experts from across the world. All comments and suggestions have been carefully considered to formulate this consensus document, which is freely available on the LPV Subgroup website. Furthermore, a list of recommendations arising from the findings in this document is also provided at the LPV webpage: It is expected that this best practice protocol will be a living document and that recommendations within will undergo regular revisions based on community feedback and advancement in the science of LST.

Earth Observations in Support of the 2030 Agenda for Sustainable Development
March 2017
At the United Nations (UN) Sustainable Development Summit on September 25th, 2015, world leaders adopted the 2030 Agenda for Sustainable Development, which includes a set of 17 Sustainable Development Goals (SDGs) to end poverty, fight inequality, and injustice, and tackle climate change by 2030. Because Earth observations provide critical data for official statistics that help address many of the SDGs, the Group on Earth Observations (GEO) is committed to organizing and realizing the potential of those data to advance the 2030 Agenda for the benefit of society through its Earth Observation for Sustainable Development Goals (EO4SDG) Initiative As the “space arm” of GEO, we (CEOS) focus our coordination efforts around satellite Earth observations, which also contribute to the SDGs in specific ways. To highlight the potential role of Earth observations for supporting the global Indicator framework for the SDGs, CEOS & GEO put together the “Earth Observations in Support of the 2030 Agenda for Sustainable Development” report. A successful sustainable development agenda will require effective partnerships for implementation. This report describes how GEO, CEOS Agencies will work with governments, academia, scientists, and the private sector to develop such partnerships for implementation of the Sustainable Development Goals.

The CEOS Data Applications Report Summary Brochure - Digital Version
December 2015
This report, compiled by the Japan Aerospace Exploration Agency (JAXA, 2015 CEOS Chair) paints a picture of the incredible breadth of applications supported by Earth observation satellite data in the service of society, science, and industry. The applications and best practices presented here by multiple CEOS Agencies represent a wide range of sectors including disaster risk reduction, public health, natural resource exploration, infrastructure planning and management, and environment and climate. CEOS Agencies continue to advance satellite applications in each sector, contributing solutions to the many challenges facing humankind. We hope that this report is useful for decision-makers and the public, and also that it may provide some new insights into the world of satellite applications to those unfamiliar with space technology.

The CEOS Statement to SBSTA-43
November 2015
This Statement is a progress report from the CEOS/CGMS (Coordination Group for Meteorological Satellites) Working Group on Climate (WGClimate) on an integrated response to the United Nations Framework Convention on Climate Change (UNFCCC) needs for global satellite observations (to be delivered during the 43rd session of the Subsidiary Body for Scientific and Technological Advice, SBSTA-43).
