The first wave of January 2010 El Nino storms (Image: USNRL)

Australia's Bureau of Meteorology predicted that at the end of this year a strong El Nino effect can bring extreme weather around the world. Computer models based on satellite and meteorological observation data made this prediction.

An El Nino comes along about every two to seven years as part of a natural cycle. It is a warming of the Pacific Ocean as part of a complex cycle linking atmosphere and ocean.

To predict an El Nino scientist designed complex computer models that are fed with satellite and meteorological observation data as well as information about the... read more

Decades of satellite images show: Earth is a cloudy place (Image: NASA)

Satellite-based Earth observation as well as images taken by astronauts show that Earth views from space are dominated by clouds. A recent study by NASA has looked at a decade of imagery and estimates that about 67 percent of Earth’s surface is typically covered by clouds.

NASA writes: "Earth’s cloudy nature is unmistakable in this global cloud fraction map, based on data collected by the Moderate Resolution Imaging... read more

Flood affected areas will suffer under the loss of rain fall satellites (Image: United States Marine Corps)

Currently, there are 10 satellites dedicated to monitoring rainfall, but soon this number is likely to fall: four satellites have already passed their design life and others will follow soon. This will strongly affect flood management globally, shows a study published at Environmental Research Letter.

Space-based rainfall observation give high-value opportunities for globally coordinated data services regarding rainfall and resulted floods. Rainfall satellite data provides a good understanding of high-intensity events like monsoon rains, meaning that flood warnings could be communicated and... read more

The new Cube+ makes it easier evaluate satellite imagery (Image: NASA)

Ecometrica announced the delivery of the new Cube+. The combination of software and customised cloud computing hardware allows sequential images taken by satellites to be built up layer upon layer, quickly and efficiently, to provide a much more detailed, and in-depth answers to complex queries about changes to agriculture, forests, coasts and urban areas.

The new technology allows government departments and firms to analyse complex data from satellites without the need for supercomputers for the first time. I will provide a more powerful service than those currently available using supercomputers, at around a tenth of the cost.

"This new Ecometrica technology component will allow businesses to efficiently process complex time-space data queries across the globe. It brings complex information retrieval tasks on... read more

Space-based monitoring helps track changes on large scales (Image: NASA)

Based on the findings of a scientific review of the draft SDGs, the experts have presented in the International weekly journal of science, Nature, five main priorities they recommend the scientific community to follow. These are: Devise metrics, establish monitoring mechanisms, evaluate progress, enhance infrastructure and standardize and verify data.

Within the priority of enhancing infrastructure, Earth observation and space-based monitoring play an important role. Together with on-the-ground observation, they could help track changes on large scales in natural-resource availability, landscape patterns and management, and social structure.

The authors also emphasize on the... read more

Moving out on Landsat 9 is a high priority for NASA and USGS (Image: NASA)

NASA and the U.S. Geological Survey (USGS) have started work on Landsat 9, planned to launch in 2023, to continue the observing programme of Earth’s land cover. Since 1972 one of the eight satellites in the Landsat program has photographed the entire Earth every 16 days and provide accurate measurements of Earth’s surface.  

With this big data, derived from decades of observations, scientists can for example tease out changes in ecosystems like deforestation in South America, the effects of climate change and many... read more

The technological improvements of the past decade have brought into scene a faster and more efficient way of working with Landsat satellite data.

Scientists and students can now spend more time analysing and evaluating instead of compiling and sorting data from satellites. The modernization of the remote sensing research process has occurred thanks to two main factors: the growth of computing power and the public and free availability of Landsat archives from 2009.

The Landsat record provides the longest continuous view of Earth’s landscape from Space, with at least one image of every location on... read more

The Food and Agriculture Organisation (FAO) of the United Nations has signed a partnership agreement with Norway in order to help developing countries assess their forest resources and changes.

Through access to Earth observation data sources and the development of an easy-to-use platform for processing and interpreting this data, the countries will be able to better monitor and report about their forest situation.

"The new platform offers countries a set of efficient tools for monitoring changes in their forest area and carbon stocks, and for developing sustainable forest management regimes", said Eduardo Rojas-Briales, Assistant Director-General of FAO's Forestry Department.

Smartphones can detect ground motion and warn others before strong shaking arrives (Image: NASA/Emiliano Rodriguez Nuesch)

A study led by scientists at the U.S. Geological Survey (USGS) has shown smartphones and other personal electronic devices could be used as early warning systems for large earthquakes.

This technology would be especially useful for regions that cannot afford the high prices of conventional early warning systems. Despite being less accurate than scientific-grade equipment, the GPS (Global Positioning System) receivers in a smartphone can detect the permanent ground movement caused by fault motion in a large earthquake, according to USGS.

Crowdsourced observations from participating users are an essential part of the earthquake warning system. “Crowdsourced data are less precise, but for larger... read more

The National Oceanic and Atmospheric Administration (NOAA) is preparing a new application to help people determine at a street-level where water could rise in a storm surge.

This experimental storm surge simulator will let people get a look at what kind of storm surges can take place in their surroundings and which can be the possible damages. The preliminary model is based on Charleston (South Carolina), USA.

"Surveys of the public show there is still a consistent misunderstanding of what the storm surge is, and how deadly it can be. In part this is due to the challenge scientists encounter in trying to simplify the complex physics of hurricanes for the public, and in part this is... read more

A recent satellite-based study published in Nature Climate Change shows the world is becoming greener despite the high deforestation of some regions.

The researchers have found that a new growth in the drier savannas and shrublands of Africa and Australia, together with recovered forests outside the tropics, is helping to balance the ongoing deforestation in areas such as South America and Southeast Asia.

The research has been developed using a new technique called “passive microwave remote sensing”. It allows to... read more

NASA's soil moisture mapper (SMAP) was launched on 31 January to map and detect global soil moisture. These maps will support the understanding of the interlinkages of Earth's water, energy and carbon cycles. The monitoring of SMAP will also promote weather and climate prediction as well as the monitoring of natural hazards.

First images of SMAP have now been made public. They demonstrate the ability of SMAP to provide comprehensive maps with a spinning instrument design. When fully operated, SMAP's antenna is able to cover the entire globe with high-resolution-data every two to three days with a 1,000 km swath from a altitude of 685 km above Earth.
