Dry, warm weather has sparked wildfires over Siberia this spring. After a limited surge in April, the countryside has lit up majorly in May. But why is this happening and how can the Sentinel satellites help?

The European Union's Copernicus Sentinel-2 satellites are supplying unprecedented views of Earth, mainly providing information for agricultural and forestry practices and helping to manage food security. But how are they making a difference to farmers in particular?

Hawaii's Kīlauea volcano has erupted again, causing an extensive explosion of sulphur dioxide and ash that could pose a risk to people's health and to aviation.

Observations derived from Synthetic Aperture Radar imagery show that wave stresses—which can be highly variable—are important external forces on sea ice within a few hundred kilometres of the ice edge.

Data from the Sentinel-1 and -5P satellites of the European Union's Copernicus programme are being used to better understand the mechanisms behind volcanic eruptions and landslides in Central Africa.

Active for decades, Kīlauea volcano - on Hawaii's Big Island - erupted on 4 May. The island also experienced a magnitude 6.9 earthquake on the same day, forcing thousands to leave their homes.

On 17 July and 21 September 2016, two unprecedented giant ice avalanches of 70 or 80 million m³, respectively, rushed down from two adjacent glaciers in Tibet with speeds of up to 300 km/h, over slopes as low as a few degrees.

In this special edition, senior project scientist at Gamma Remote Sensing, Dr Maurizio Santoro, joins the show to discuss how his team estimates forest biomass from space.

The European Union's Copernicus Sentinel-1 satellites, together with the COSMO-SkyMed constellation, provided important data related to the 2017 Ischia earthquake.

On 17 February 2018, the Sentinel-2 mission reached the 5-day global revisit periodicity, thus fully exploiting the two satellite units of the constellation.

The Sentinel-1 satellites of Europe's Copernicus Programme are being used to quantify the surface deformation of the disaster area around the Hualien earthquake.

The Sentinel-3B satellite scheduled for launch this spring, will be flying 30 seconds apart from its twin, Sentinel-3A, during the commissioning phase. This temporary tandem arrangement is to obtain better cross-calibration between instruments, thus reducing uncertainties in the multi-satellite time series and ensuring an overall high data quality.

Observations by the Copernicus Sentinel satellites over Mount Agung in Bali, are helping scientists to monitor the ongoing eruption and identify any changes in magma pressure, possibly indicating whether a bigger eruption could occur.

Wave information is crucial for people working at sea, to be able to navigate and operate safely. A new product based on satellite altimeter data detailing ‘Significant Wave Height' now enables this.

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.

Carrying advanced radar instruments, which can image Earth's surface regardless of the weather and darkness, the Copernicus Sentinel-1 mission is bringing new insight into the aftermath of heavy rains and hurricanes.

The Copernicus Sentinel satellites have proven to be invaluable for various activations of the International Disasters Charter.

In October 2017, a series of wildfires broke out in northern California, killing many and burning thousands of acres of land. Satellite imagery and particular data processing techniques are being used to help map the extent of the damage.
