watchITgrow: Was it a success?

The first growing season in which the satellite monitoring programme watchITgrow was widely available to Belgian potato growers is coming to an end. Tentative conclusions about the concept’s use can now be drawn.

Sentinel-2 cloudless mosaic: the first global (almost) cloud-free view of planet

About 70 per cent of the Earth’s surface is covered by clouds any given day. Imagery obtained by satellite sensors operating in the visible light range is constantly constrained by clouds blocking the view of the surface of the Earth and shadows obscuring or distorting features on the ground.

These shadows and clouds can often ruin the acquired satellite imagery in regards to requirements. So how can we get a global cloud-free view of the Earth through using Sentinel-2?

EOX IT Services, an Austrian Open Source solution provider for Earth Observation services, has implemented a methodical process crafting an almost cloudless Sentinel-2 map of the world, which has been viewed more than 450,000 times during the last two weeks on the company’s website.

This Sentinel-2 cloudless layer combines over 80 trillion pixels collected under various weather conditions between May 2016 and April 2017 (images of Northern hemisphere’s mosaics were taken between May and September 2016, while the Southern hemisphere images were taken between November 2016 and March 2017). The pixels were then merged into a sunny homogeneous mosaic, free of any cloud cover.

NASA Looks Within Category 5 Hurricane Maria Before and After First Landfall

Satellite data is enabling forecasters to look inside and outside of powerful Hurricane Maria. A NASA animation of satellite imagery shows Hurricane Maria's first landfall on the island of Dominica. NASA's GPM satellite provided a 3-D look at the storms within that gave forecasters a clue to Maria strengthening into a Category 5 storm, and NASA's Aqua satellite gathered temperature data on the frigid cloud tops of the storm.

Arctic sea ice once again shows considerable melting

This September, the extent of Arctic sea ice shrank to roughly 4.7 million square kilometres, as was determined by researchers at the Alfred Wegener Institute, the University of Bremen and Universität Hamburg. Though slightly larger than last year, the minimum sea ice extent 2017 is average for the past ten years and far below the numbers from 1979 to 2006. The Northeast Passage was traversable for ships without the need for icebreakers.

The sea ice in the Arctic is considered a critical element in climate processes, and a valuable early-warning system for global warming. Accordingly, the September minimum extent is an important indicator of climate change. Despite an especially warm winter, the current extent of sea ice does not represent a new record low; nevertheless, the amount of ice loss is massive. As sea-ice physicist Marcel Nicolaus from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) explains, “This year’s sea ice extent is again on a very low level: the observed September value of the past eleven years has consistently been lower than in any of the previous years.”

IGARSS will come in Brussels in 2021

As co-organizer, BELSPO STEREO team is very proud to announce that the organisation of IGARSS 2021 has been awarded to the Low Countries (Belgium and The Netherlands).

IGARSS (IEEE International Geoscience and Remote Sensing Symposium) is one of the most important international meetings in the field of remote sensing attracting thousands of scientists all over the world.

The event will take place in Brussels on July 11-16 July 2021.

It's a great opportunity for our countries and our scientific communities.

The Local Organising Committee hopes that you will turn out en masse to present your work
to the international community and make it a fun event!
