Notes from the Field: Olympic Mountains Experiment (OLYMPEX)

In the winter of 2015-16, scientists will be working to validate rain and snow measurements from the Global Precipitation Measurement (GPM) constellation of satellites by monitoring storm systems as they approach and traverse the Olympic Peninsula in Washington. Read more

 A Little Bit of Water, A Lot of Impact

A Little Bit of Water, A Lot of Impact

Compared to the amount of water stored in the oceans, ice caps, and lakes, the amount in the soil is minuscule. But that small volume has great significance for weather and climate. Read more

Notes from the Field: North Atlantic Aerosols and Marine Ecosystems Study (NAAMES)

Notes from the Field: North Atlantic Aerosols and Marine Ecosystems Study (NAAMES)

Scientists are embarking on a five year air and sea investigation to understand key processes that control the ocean system, their influences on atmospheric aerosols and clouds, and their implications for climate. Read more

Snowpack in the Sierra Nevada

Snowpack in the Sierra Nevada

Wet and dry years cause the snow cover to fluctuate, but the overall trend has been downward for nearly a decade. Read more

CYGNSS: Gearing Up to Look Down on Hurricanes

When launched in 2016, the Cyclone Global Navigation Satellite System (CYGNSS) will be a constellation of eight micro-satellites that will make accurate measurements of ocean surface winds in order to better understand the lifecycle of tropical cyclones, typhoons and hurricanes. Read more

World of Change: Water Level in Lake Powell

World of Change: Water Level in Lake Powell

Combined with human demands, a multi-year drought in the Upper Colorado River Basin caused a dramatic drop in the Colorado River’s Lake Powell in the early part of the 2000s. The lake began to recover in the latter part of the decade, but as of 2015, it was still well below capacity. Read more

Science in a Dark Freezer: A Tale of Icy Beards, Frozen Tools, and Wintering Over at the South Pole

NASA scientist Robert Benson was one of “eighteen crazy men and a dog” who set up the first permanent science base at the South Pole. Read more

Big Data Helps Scientists Dig Deeper

Big Data Helps Scientists Dig Deeper

Empowered by free access to the Landsat data archive, earth scientists are using new computing tools to ask questions that were impossible to answer a decade ago. From week-to-week fluctuations in forests to year-to-year changes in land cover, researchers can now examine our planet in much greater detail. Read more
