Shiptracks in the atmosphere are visible in this image from NASA’s Terra satellite’s Moderate Imaging Spectroradiometer (MODIS) as part of the new feature, Reading the ABCs from Space from NASA’s Earth Observatory. N is for New Year was the final Image of the Day for 2015.

NASA Features from AGU: Terra

The American Geophysical Union recently concluded its Fall meeting in San Fransisco, California from December 14 – 18, 2015.  As part of the meeting contributions to science were featured on NASA.gov.  Data from Terra’s instruments played important roles in collecting data to further research in each of these featured areas.  Read the full features from NASA.gov available at the links below.

El Niño

NASA: Observing the 2015 El Niño – The strongest El Niño since 1997 – 1998 is being monitored for the first time by a host of satellites, including Terra. This video (above) features global data sets from Terra’s instruments and their contribution to El Niño research.

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.

A Fault Runs Through It

Aster Image of Patrick Island

NASA Earth Observatory image by Jesse Allen, using data from NASA/GSFC/METI/ERSDAC/JAROS, and U.S./Japan ASTER Science Team.

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite, captured the image of Prince Patrick Island in Northern Canada. The image was featured on NASA’s Earth Observatory, showing the dendritic drainage pattern of interlocking steam and river channels, as well as, strike-slip faults, evidence of Prince Patrick’s seismic history. Prince Patrick Island is usually surrounded in sea ice, while temperatures average -33 degrees Celcius in January. This cold, inhospitable terrain is not a frequent travel destination, but through satellite imagery, much can be learned about this mostly uninhabited part of our planet.

A New Identity for Denali

denali_oli_2015166_renderMount Denali received not only a new name on August 30, 2015, it also received a new elevation.  Using the Global Digital Elevation Model (GDEM) product from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data, the listed elevation for Moutn Denali went from 20,320 feet to 20,310 feet. The reduction in elevation was due to a more detailed global elevation survey made possible with the high resolution data from ASTER in the GDEM.  Better technology led to a more accurate elevation.
