The 2020 United Nations/Austria Symposium "Space Applications for Sustainable Development Goal 13: Climate Action" organized by UNOOSA will take place from 1-3 September. It will discuss how space technologies support climate action.

Climate action is one of the most pressing priorities for action within the Sustainable Development Goals framework. The last 5 years were the hottest on record and 14 of the 15 hottest years have occurred since 2000. Average sea levels have risen by 23 cm since 1880 and by 9 cm in the last 25 years. Earth observation is an essential tool to monitor these changes: out of the 50 essential climate change variables, 26 can only be measured from space. Space technologies can contribute significantly to global efforts to mitigate and adapt to climate change. This becomes evident when mapping contributions of space-based technologies to the SDGs: out of the 169 SDG targets, 65 are reliant on geolocation or Earth observation.

This short course is an opportunity to get an overview about the climate data records available from the EUMETSAT Satellite Application Facilities, learn how to access them and gain some first experiences in how to working with these free and open data in the CM SAF - R -Toolox. Participants will have the opportunity do hands-on exercises using the data. Data and software developers will be available online to help and answer questions.

Climate Scale interactive web map
Publishing institution: Climate Scale
Climate Scale offers an easy to access, current climate variability and future climate projections, building on the consolidated experience of Vortex technology to physically downscale climate data to the resolution for local applications

The Global Ecosystem Dynamics Investigation (GEDI) produces high resolution laser ranging observations of the 3D structure of the Earth. GEDI’s precise measurements of forest canopy height, canopy vertical structure, and surface elevation greatly advance our ability to characterize important carbon and water cycling processes, biodiversity, and habitat. GEDI’s data on surface structure are valuable for weather forecasting, forest management, glacier and snowpack monitoring, and the generation of more accurate digital elevation models.

ESA's Earth Observation Thematic Exploitation Platform (TEP) is a browser for satellite imagery and specific products on an environmental topic. The TEP platforms are divided into 7 categories: Coastal; Forstry; Geohazards; Hydrology; Polar; Urban; and Food Security. Each platform is a collaborative, virtual work environment providing access to EO data and the tools, processors and Information and Communication Technology resources required to work with them. TEP aims to bridge the gap between the users and the data and tools.

Wetlands of Uganda from Copernicus Sentinel data. Image: ESA

The European Space Agency’s (ESA) GlobWetland Africa project has produced maps that demonstrate how satellite observations can be used for the effective use and management of wetlands in Africa. The project, created in collaboration with the African Team of the Ramsar Convention on Wetlands, provides national and international stakeholders with the necessary satellite-based methods and tools useful for the conservation and effective management of wetlands. 

The initiative provides a software platform built on the free and open-source QGIS geographic information system (GIS). The platform shows how optical and radar observations combining long-time data sets from different satellites can be used for studying wetland status and trends. For instance, the project shows how it is possible to map wetland habitat using a Random Forest (RF) classification of multi-spectral satellite imagery from Sentinel-2 and Landsat (TM, ETM, OLI). To identify wetland inventory... read more

Scientists from 50 scientific institutions, led by the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) combined 26 independent satellite datasets to show that the Greenland Ice Sheet melt is increasing. The group studied data from 1992 to 2018, taking direct measurements of the continent-sized glacier. The study found that decade averages for ice melt has increased sevenfold from the 1990s. 

The report shows that 1992 to 2002 averaged 1mm/decade in melt, 2008 to 2018 increased to a 7mm/decade loss. The research pulled from USGS’s Landsat mission, the oldest open-access Earth observation data. The total was also calculated using space-based gravity measurements - which measures total mass on the world’s largest island - integrated with remotely sensed height measurements and water flow models to create an Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE) for a complete understanding of the total ice found on... read more
