Satellites show earlier snowmelt in Wyoming, USA

Change in snow cover in analysed decades (Image: NASA)

A new NASA study about snowmelt in Wyoming shows, that the snow in a basin in northwest Wyoming now disappears about 16 days earlier than it did in the period from the 1970s through the 1990s. Snowmelt, as a water source, has a significant impact on agriculture and ecosystems in Wyoming.

The lead spacecraft built within the Europe's new Earth observation (EO) programme is ready to go into orbit. Sentinel-2a will track everything from the growth of megacities to the variable yields of the world's most important food crops through pictures of the planet's surface. The satellite's launch on a Vega rocket has been scheduled for 12 June 2015.

USGS: New land cover data released for Alaska

Three panels from the National Land Cover Database depicting land cover change in the vicinity of Fairbanks, Alaska, from 2001 to 2011

The U.S. Geological Survey (USGS) has released a new dataset for land cover in Alaska; it is publicly available and covers ten years. Based on Landsat satellite imagery taken in 2011, the data describe the land cover of each 30-meter cell of land in Alaska and identifies which ones have changed since the year 2001.

Sweden: Unusually intense wildfires captured by satellite

This natural-color image of the fire in Sweden was captured by Landsat 8

Sweden is not a country typically known for its summer wildfires. Fires occur regularly, but not in the intesity of this year's blaze that has been affecting the region of Västmanland since 31 July 2014.

The fire grew to the largest one in 40 years. It has affected more than 150 square kilometers, killed one person and forced thousands to evacuate.

Regional Consultation Workshop on MODIS Products and Services for Regional Environmental Applications and Automated Forest Cover Monitoring for Hot Spots using LANDSAT data

This is event is available for participation on an ongoing basis
English

The knowledge on natural resources accounting to support subsistence livelihoods and environmental conservation is a critical and perennial need in theHindu Kush Himalaya (HKH) region. The changing dynamics of snow and glaciers, atmospheric pollution and transport, inter and intra annual patterns of water availability and crop production, dynamics of land cover and vegetation phenology are some of the processes which largely affect natural resource support and govern the quality of living.

Sinabung Volcano: Detecting pyroclastic flow from space

The eruptions of Mount Sinabung are less violent now, but they are not over.

In January 2014, Mount Sinabung on Indonesia's Sumatra island has exploded intensively and repeatedly, forcing thousands of residents to vacate their houses. While eruptions have weakened and are less violent now, the volcanic activity of Mount Sinabung is ongoing.

NASA's Landsat satellite has captured the ash plume and pyroclastic flow from the volcano on 6 March 2014. The false-color image clearly shows the pyroclastic flow in red on the eastern flank of Sinabung.
