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

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

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

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

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.
