White Paper: Satellite Mapping in Response to the 2016 7.8 Magnitude Earthquake in Muisne, Ecuador
November 2019
This document describes how satellite Earth Observation (EO) contributed to the response of the 2016 earthquake in Ecuador. It focuses on the available EO disaster response capabilities and how they supported the local disaster management authorities by gathering satellite images and generating satellite-derived maps and reports to identify the extent of the affected area, assess the damage and provide a clearer view about the nature of the event.

Geostationary Satellite Constellation for Observing Global Air Quality: Geophysical Validation Needs
October 2019
This whitepaper elaborates the validation needs and inter-mission consistency targets of the Geo-AQ constellation. This constellation consists of the geostationary atmospheric composition missions GEMS, Sentinel-4, and TEMPO, which provide hourly observations of key air pollutants, and is complemented by low Earth orbiting missions with a strong focus on air quality. Recommendations are made for activities that are needed to address new challenges associated with the geostationary perspective, to assess and establish the consistency of data products, and to enhance the impact of the individual missions as elements of a constellation.

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.
