First Data Released From ESA Satellite Sentinel 3-A

Liam Oakwood

The European Space Agency and Eumetsat have just released the first data from their new satellite platform, Sentinel 3-A. This groundbreaking new Earth observation platform can monitor a wide range of Earth systems, and will play a vital role in understanding our planet into the future.

Changes in Cambodia from Sentinel-1A readings at 20 m resolution, acquired every 12 days from March 2015 to March 2016. Dark blue represents water surfaces, light blue to magenta represents agriculture (bare soil and cultivated fields), light to dark green represents forests, and white indicates settlements. In particular, the varying shades of magenta indicate rice sowing and transplanting between mid-September and the end of October.

Using Remote Sensing to Map Rice Paddy Drop in the Mekong Delta

Elizabeth Borneman

Satellites including Europe’s Sentinel-1A can now track the rise and fall of different agricultural products around the world. The satellite’s imagery showed that rice production in the Mekong Delta has decreased in the past year.

This map of Greenland ice sheet velocity was created using data from Sentinel-1A in January–March 2015 and complemented by the routine 12-day repeat acquisitions of the margins since June 2015. About 1200 radar scenes from the satellite’s wide-swath mode were used to produce the map, which clearly shows dynamic glacier outlets around the Greenland coast. In particular, the Zachariae Isstrom glacier in the northeast is changing rapidly, and recently reported as having become unmoored from a stabilising sill and now crumbling into the North Atlantic Ocean. (Colour scale in metres per day).

Ice Loss in Greenland

Elizabeth Borneman

Recent research has shown that one of Greeland’s largest glaciers is losing up to five billion tons of ice every year as it melts into the ocean.

Acquired on 27 June 2015 at 10:25 UTC (12:25 CEST), just four days after launch, this close-up of France’s southern coast from Nice airport (lower left) to Menton (upper right) is a subset from the first image from the Sentinel-2A satellite. This false colour image was processed including the instrument’s high-resolution infrared spectral channel.

Using 200 million measurements collected by ESA’s CryoSat mission between January 2011 and January 2014, researchers from the Alfred Wegener Institute in Germany have discovered that the Antarctic ice sheet is shrinking in volume by 125 cubic kilometres a year. The study, which was published in a paper published on 20 August 2014 in the European Geosciences Union’s Cryosphere journal, also showed that Greenland is losing about 375 cubic kilometres a year
