SAM Satellite

ESA’s Soil Moisture and Ocean Salinity (SMOS) mission is dedicated to making global observations of soil moisture over land and salinity over oceans.

The SMOS satellite carries a novel interferometric radiometer that operates in the L-band microwave range to capture ‘brightness temperature’ images.

These images are used to derive global maps of soil moisture every three days, achieving an accuracy of 4% at a spatial resolution of about 50 km. Over oceans, SMOS maps salinity down to 0.1 practical salinity units (psu, averaged over 10–30 days in areas measuring 200 × 200 km).

According to the latest issue of an annual disaster statistics report, floods were the deadliest type of disasters in 2019, followed by extreme temperature, while storms affected the highest number of people. Published by the Centre for Research on the Epidemiology of Disasters (CRED), “Natural disasters 2019 - Now is the time to not give up” draws on data recorded in the Emergency Events Database (EM-DAT), which saw the addition of 396 disasters that affected a total of 95 million and caused $103 billion in economic losses around the world. 

Accounting for 40 per cent of disaster events, Asia suffered the highest impact with 45 per cent of deaths and 74 per cent of total affected. India, which saw cyclone Fani cause destruction in 2019, was the country most affected... read more

Nepalese Space Research Association (NESRA) is organizing a webinar “Space Technologies for Efficient Disaster Management”, which will be led by distinguished people who have worked to mitigate the effects of disasters using space technologies. The seminar is concerned with how space technologies contribute to efficient disaster management, especially in the wake of the recent flood and landslide risks in Nepal. The benefits of space technologies in the prevention and mitigation of natural disasters will be highlighted.   The main speakers will be:  
  • Abhas Maskey, BIRDS-3 Satellite Project Manager (first satellite of Nepal)
  • Reshma Shrestha, Asst. Professor, Department of Geomatics Engineering, Kathmandu University, Nepal
  The moderator will be:  
  • Anmol Mittal, President, Nepalese Space Research Association (NESRA)

World Congress on Disaster Management (WCDM) is a unique initiative of DMICS to bring researchers, policy makers and practitioners from around the world in the same platform to discuss various challenging issues of disaster risk management. The mission of WCDM is to promote interaction of science, policy and practices to enhance understanding of risks and advance actions for reducing risks and building resilience to disasters.

The Conference will discuss various topics, including:

  • Remote Sensing, GIS and Drones for Disaster Risk Management
  • Early Warning of Hydro-Meteorological Disasters: Tasks Ahead
  • Early Warning of Earthquakes: How Far, How Near
  • Operationalising Early Warning of Landslides
  • Application of Artificial Intelligence for Managing Risks of Disasters
  • Emerging Technologies for Climate & Disaster Resistant Agriculture
The Conference will provide in-depth analysis of the following... read more

The European Space Agency’s Earth Observation for Sustainable Development (EO4SD) Climate Resilience Cluster is hosting a free webinar to provide insight about the potential of Earth Observation (EO) to support climate-resilient decision making at the regional and national scale.

Earth Observation (EO) data and services are vital tools for the water sector, supporting flood events, and conducting wetland inventory status in rural and urban areas. EO provides valuable information (Flood extent, historical flood events etc.) with the aim to assist authorities to prepare the most effective actions to manage flood risk and develop plans to tackle disasters. The fourth webinar of series will present in detail how Earth Observation data with different spatial and temporal resolution can contribute to flood risk, water and wetness management.

EO4GEO aims to bridge the skills gap between the supply and demand of education and training in the space/geospatial sectors, fostering the uptake and integration of space/geospatial data and services in a broad range of application domains. 

The event includes sessions on:

  • Introduction to Copernicus and Services (with COVID-19 examples)
  • The role of Earth Observation in emergency situations
  • NO2 Air pollution monitoring 
  • Three case studies on how satellite data combined with other data is valued for agriculture, nature conservation and monitoring of forest for detection of fire and diseases
  • The role of EO in emergency situations
  • Maritime Spatial Planning.
