Rivers are among the most degraded ecosystems on Earth. The first map of river color from Landsat surface-reflectance data shows one third of U.S. rivers have changed color significantly over the last 35 years.

In mid-January, the U.S. Pacific Northwest was soaked by several episodes of heavy rainfall, leading to widespread flooding and landslides. NASA data show these rivers in the sky.

NASA is tracking the effects of the COVID-19 pandemic on our air, land, water and climate. The data have been collected in a free, openly-available online dashboard.

Launched three weeks ago, the Sentinel-6 Michael Freilich satellite has returned its first data and is surpassing expectations. The NASA-U.S.-European satellite will measure sea-level rise with unprecedented accuracy.

Floods are the most deadly and costly natural hazard. A NASA team is streamlining access to real-time satellite data so disaster managers can make informed decisions, faster.

NASA scientists Dalia Kirschbaum and Maggi Glascoe are using satellite data to pioneer improved landslide and flood alerting around the world.

NASA has accumulated 40 petabytes of Earth science data, twice as much as all of the information stored by the Library of Congress. In the next five years, that will grow to 250 PB. 11 new projects are launching to help manage, store and search these data.

Water managers need accurate, consistent and timely data. A new online platform called OpenET puts NASA data in the hands of farmers, water managers and conservation groups.

On the Navajo Nation, access to drinking water is limited. Over 40 percent of homes lack running water. The community is hit by frequent, pervasive drought. WWAO is developing a new drought tool that, with the help of satellite data, will enable Navajo water managers to hone in on drought severity and better manage the water they have.
