The Rains of Roanu

May 24, 2016 

Tropical Storm Roanu made landfall in Bangladesh, unleashing heavy winds and rain on the country’s populous coastal communities. On May 21, 2016, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this natural-color image of the storm. Roanu progressed northeast over the Bay of Bengal before making landfall in Bangladesh.

Early Breakup of the Beaufort Sea Ice 

May 20, 2016 

The Beaufort Sea ice pack starts to thin and break up in spring when temperatures begin to rise, usually in late May. However, much of the Beaufort Sea’s ice had already broken by mid-April. Images from the Moderate Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured the progression in April in 2014, 2015, and 2016.

Using Clouds to Map Life – A team of researchers are using cloud data from the Moderate Imaging Spectroradiometer (MODIS) on NASA’s Terra Satellite to create detailed maps of cloud cover and variability. The team found that cloud cover could be an indicator and a better predictor of a songbird and flower’s range than temperature and precipitation.

Sierra Nevada Snowpack is Better, But not Normal – Snowpack in the Sierra Nevada mountains dwindled over recent years; however, the winter of 2015-2016 and the strong El Nino provided a thicker and more extensive snowpack. Regardless, snow levels in the Sierra Nevada mountains were still below average. Images from NASA’s Moderate Imaging Spectroradiometer (MODIS) clearly show the difference between years.

Greening Ascension Island – When Charles Darwin first visited Ascension Island it was barren, but with the assistance of Joseph Hooker in the 1800s plants were introduced and now cover much of this once bleak island. The image from the Advanced Spaceborne Thermal Emissions and Reflection Radiometer (ASTER) on NASA’s Terra satellite shows the now green Ascension Island and it’s Green Mountain.

Pavlov Erupts Again – Pavlov Volcano, Alaska’s most active volcano, began erupting for the first time since November 2014. The Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on NASA’s Terra and Aqua satellites acquired images of the ash plume at 11:45 a.m on March 28, 2016.

Mount Erebus, Antarctica – Mount Erebus in Antarctica, thought to be the most southern volcano is still active. The Advanced Spaceborne Thermal Emissions and Reflection Radiometer (ASTER) on NASA’s Terra satellite captured images in visible and infrared, showing not just the volcano, but also the lava lake in its interior.

Torrential rains in late October 2015 resulted in flooding in Iraq, prompting authorities to declare a state of emergency. Widespread power outages, overflowing sewers, and flooded streets displaced almost 84,000 people, according to news reports. The image from the Moderate Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite, featured on NASA’s Earth Observatory, shows the flooding.
