NASA Monitoring System

NASA scientists have developed a regional visualisation and monitoring system for Central America and the southern Mexican states designed to make NASA Earth observations and predictions freely and readily accessible to anyone with an internet connection. The system’s Spanish acronym is SERVIR, which means 'to serve' and it features a Web-based data archive of maps and satellite imagery, decision-support tools and interactive visualisation capabilities. NASA devised the system in partnership with several other organisations, among them the US Agency for International Development, the World Bank and the Central American Commission for Environment and Development. Scientific and technical collaborators include the... (read more)

Volcano Monitoring Improvements

Scientists from the USGS work with partners around the world to actively monitor the world’s volcanoes. They use seismometers to detect and monitor very small earthquakes that indicate that magma is rising. They also use GPS to detect changes in the size of the volcano. Volcanoes can be catastrophic. Lava flows and debris avalanches can choke major riverways, destroy bridges and devastate natural areas. The USGS has allocated over USD7 million in American Recovery and Reinvestment Act funds to 15 universities and state agencies nationwide to modernize the equipment in volcano monitoring networks and produce high-resolution maps of high-threat volcanoes....

Monitoring Russian Wildfire Rage

Wildfires in Yakutia, Russia, are being monitored by ScanEx specialists. Over the past week UniScan ground stations have received highly detailed optical images from the SPOT 5 satellite covering one and the same territory twice within an interval of several days. Multi-temporal satellite imagery enables to assess the changes in burnt areas, smoke direction and fire intensity. Data about the geography of possible fires is updated daily on the thematic SFMS service "Kosmosnimki - Fires" (see link below). According to mass media the area of natural fires almost doubled the 2010 figures. If in 2010 the fire blazes covered the... (read more)

Monitoring the Changing World

More than 200 researchers from over 24 countries congregated at the biennial POLinSAR workshop held at European Space Agency’s (ESA) centre for Earth observation in Italy. The workshop aimed to provide an opportunity to review the advances made in the technique of Synthetic Aperture Radar (SAR) polarimetry which facilitates monitoring geographical characteristics that may influence changes in the world and climate.   SAR allows polarised information to be measured in the signals backscattered from Earth to a satellite sensor. Polarimetric interferometry is achieved by using two polarimetric images, acquired from slightly different angles, to provide information on the 3D structure... (read more)

Monitoring Earth's Magnetic Heartbeat

With more than two years of measurements by ESA’s Swarm satellite trio, changes in the strength of Earth's magnetic field are being mapped in detail. Launched at the end of 2013, Swarm is measuring and untangling the different magnetic signals from Earth’s core, mantle, crust, oceans, ionosphere and magnetosphere – an undertaking that will take several years to complete. Read on to see an animation of new results from the constellation of Swarm satellites showing where the protective field is weakening and strengthening, and importantly how fast these changes are taking place. Although invisible, the magnetic field and electric currents in and around... (read more)

Monitoring Tsunami Disaster Areas

Space-based imagery is being used to assess disaster areas and direct relief efforts in areas hit by the tsunamis on 26th December 2004. Canada's RADARSAT-1 satellite previously acquired over 70 archived images of the affected regions and these are being used as baseline information to be compared with newly acquired imagery. Day and night, the satellite provides synoptic coverage up to 500km by 500km per image and collects information through clouds over areas currently experiencing monsoon conditions. This data is used to monitor and map flooding, and to locate areas of standing water creating potential breeding ground for mosquitoes carrying... (read more)

Drought Monitoring Using Gravity

The record-breaking drought in Texas, USA, that has fuelled wildfires, decimated crops and forced cattle sales has also reduced groundwater levels in much of the state to their lowest levels in more than 60 years, according to new national maps produced by NASA using data from the NASA/German Aerospace Center Gravity Recovery and Climate Experiment (Grace) mission. The map are distributed by the National Drought Mitigation Center at the University of Nebraska-Lincoln.     The latest groundwater map, released at the end of November 2011, shows large patches of maroon over eastern Texas, indicating severely depressed groundwater levels. The maps,... (read more)

Monitoring Rice from Space

Rice is the most important staple grain in the world. Ninety per cent of rice plantations are distributed across Asia, providing daily food for 2.5 billion people in this region. Rice plays an important role in the development of society and the civilisation of countries in Asia. Launching a satellite dedicated to rice monitoring is highly desirable for Asia and other countries of the world where rice is produced. RICESAT In 1999, when the Asian Association on Remote Sensing (AARS) celebrated the twentieth anniversary of the Asian Conference on Remote Sensing (ACRS) in Hong Kong, China, I proposed RICESAT.

Satellite-based Environmental Monitoring

A group of Saudi Arabian and European partners have completed a project to implement and provide satellite based environmental information products and services to the Presidency of Meteorology and Environment (PME) of the Kingdom of Saudi Arabia (KSA). The environmental monitoring covers all four environmental domains "land - air - coast - marine" and follows previous experience gained in the European GMES - "Global Monitoring for Environment and Security" programme. The providers are Summit Geoservices (KSA) and a European team lead by GAF and consisting of DLR, Germany and e-GEOS, Italy. The environment has become a synonym for quality of... (read more)

Monitoring Vulcanoes with UAS

Testing the Suitability of Thermal Infrared Sensors
Insight into signs that prelude volcanic eruptions is key for protecting the lives, livestock and property of those living in the vicinity of a volcano. One key indicator is temperature rise. Using Mount Etna as a test site, the authors show that a UAS equipped with a thermal infrared sensor generates data similar to temperature data acquired by ground-based stations while avoiding safety risks for volcanologists.   Data from Earth observation satellites with high temporal resolution can be used to monitor volcanic eruptions on an intraday basis when combined with images from satellites with a high GSD but low repetition...
