Space helps forests regenerate

10 January 2018

Many of us probably think of trees during the festive season more than any other time of the year. With Christmas trees now discarded and decorations packed away, we will be turning our attention back to daily life. The task of cultivating and regenerating forests, however, is a year-long concern – but one that can be made easier and cheaper thanks to satellites and cloud-computing.

2017 extends exceptionally warm period, first complete datasets show

04 January 2018

The first complete temperature datasets for 2017 show that last year was the third in a row of exceptionally warm years, the Copernicus Climate Change Service (C3S) implemented by the European Weather Centre (ECMWF) can announce.

Study finds first direct proof of ozone hole recovery due to chemicals ban

04 January 2018

For the first time, scientists have shown through direct satellite observations of the ozone hole that levels of ozone-destroying chlorine are declining, resulting in less ozone depletion.

Scientists probe water inside leaves via satellite

02 January 2018

Sensors on board satellites are able to detect a host of environmental metrics, from Arctic sea ice melt to the reproductive patterns of mule deer to logging and land clearing. One satellite-based measurement, called vegetation optical depth, is often used to track how plant life is responding to changes in climate.

NASA-led study solves a methane puzzle

02 January 2018

A new NASA-led study has solved a puzzle involving the recent rise in atmospheric methane, a potent greenhouse gas, with a new calculation of emissions from global fires. The new study resolves what looked like irreconcilable differences in explanations for the increase.

Sentinel-3 helps water quality monitoring

21 December 2017

Monitoring large, remote bodies of water is logistically challenging, time consuming and expensive. Responding quickly to events that pose a risk to human health has been almost impossible, given the size of some lakes and seas. An innovative satellite data service is now able to change things around.

Wet winters may not dampen small wildfires

21 December 2017

NASA scientists conducting research on the connection between fuel moisture and fires have uncovered a paradox: a wet winter corresponds to more small wildfires in the following fire season, not fewer, as is commonly assumed. Large fires behave more "logically", with fewer large fires after a wet winter and more after a dry one.

California fires: Sentinel satellite tracks wildfire smoke plume

16 December 2017

Europe's new Sentinel-5P satellite has captured a dramatic image of the smoke billowing away from the devastating California wildfires.

It is a powerful demonstration of 5P's ability to sense the atmosphere.

NASA researchers share perspective on key elements of ozone layer recovery

14 December 2017

Each year, ozone-depleting compounds in the upper atmosphere destroy the protective ozone layer, and in particular above Antarctica. The ozone layer acts as Earth's sunscreen by absorbing harmful ultraviolet radiation from incoming sunlight that can cause skin cancer and damage plants, among other harmful effects to life on Earth.

Special Issue of ISPRS journal - Urban environment mapping using GIS

12 December 2017

An upcoming special issue of the ISPRS international journal is dedicated to providing an overview of space-borne and airborne remote sensing and GIS research. It will focus on applications for urban areas and will explore future trends of concepts, methods, implementations, validations and applications.

New satellite imagery reveals new highest Antarctic Peninsula mountain

11 December 2017

Cartographers surveying Antarctica have discovered Mount Hope is the tallest mountain in the British Antarctic Territory (BAT) at 3,239 m (10,654 ft) above sea level. Until now, maps showed Mount Jackson as the tallest mountain in the territory at 3,184 m (10,444 ft). New satellite data reveals this isn't the case, with Mount Hope being 55 m taller than Mount Jackson and 377 m higher than previously thought.

'Smoke rings' spotted in the ocean from space

11 December 2017

Researchers from the University of Liverpool have spotted the equivalent of smoke-rings in the ocean which they think could 'suck-up' small marine creatures and carry them at high speed and for long distances across the ocean.

Take the driver’s seat on sea level science

30 November 2017

A new NASA sea level simulator lets you bury Alaska's Columbia glacier in snow, and, year by year, watch how it responds. Or you can melt the Greenland and Antarctic ice sheets and trace rising seas as they inundate the Florida coast.
