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.
