When Typhoon Lan made landfall in Japan on Oct. 22, the Global Precipitation Measurement mission core satellite or GPM analyzed the storm and added up the high rainfall that it generated.

Hofsjökull Ice Cap Gains Mass for the First Time in Twenty Years

18 November, 2015

iceland_tmo_2015313The Moderate Imaging Spectroradiometer on NASA’s Terra satellite captured a view of the Nordic island, Hofsjökull, on November 9, 2015. The island is experiencing its first gain in mass. Since 1995, the ice caps in Iceland have been retreating and losing volume, however in October 2015, ground based measurements showed that the Hofsjökull ice cap gained mass.

Eruption of Mount Rinjani, Indonesia

7 November, 2015

rinjani_tmo_2015307An image from the Moderate Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured the eruption of Mount Rinjani in Indonesia, blanketing ash across three Indonesian Islands. The plume was 3.5 kilometers (11,500 feet) above sea level and moved westward, affecting air travel in early November. The image was featured on NASA’s Earth Observatory.

2015 a Dry Year for Snowpack in the Sierras

sierranevada_tmo_2015090Snowpack in the Sierra Nevada range in Central California is at a record low. The Moderate Imaging Spectroradiometer on NASA’s Terra satellite captured this image, published on NASA’s Earth Observatory, of the Sierra Nevada, showing just how brown these typically very white, snow covered mountains have become since 2011, a wet and snowy year with extensive snow pack. To compare images from 2011 with 2015, used the image comparison tool on the NASA Earth Observatory site.

Since 2011, winter snow pack decreased, reducing amounts of melt water in the spring and summer. In March of 2015, ground-based monitoring sites in the Sierras reported that there was no snow cover for the first time ever, while about one-third of the sites were measuring at the lowest snow pack ever recorded.

In a recent article in Nature Climate Change, scientists from the University of Arizona used tree-ring records of precipitation anomalies to construct a 500-year history of snow water equivalent on the Sierra Nevada, showing just how unprecedented this lack of snow pack is in the past 500 years.

Fall Color Arrives in the U.S. and Canada

Fall colors on eastern seaboard as seen by Terra MODIS

NASA images by Jeff Schmaltz, LANCE/EOSDIS Rapid Response.

It’s time for the annual Fall color display across part of the Northern Hemisphere.  The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured the colorful changing foliage on October 11, 2015. As temperatures drop and sunlight fades, the leaves begin to change colors. This image was recently featured on NASA’s Earth Observatory.

Shrinking Shoreline of the Salton Sea

Salton Sea as seen by ASTER

NASA Earth Observatory images by Jesse Allen, using ASTER data from NASA/GSFC/METI/ERSDAC/JAROS, and U.S./Japan ASTER Science Team, and Landsat data from the U.S. Geological Survey.

Fed primarily from agricultural irrigation runoff, the Salton Sea in southern California’s Sonoran Desert has dropped by 8 feet since 1984. While drought in California has contributed to the receding shoreline, water conservation efforts also play a role. The sea may be reduced to two small pools by the 2030s. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite captured this image showing the exposed Deltas along its southern shore.
