An Illinois initiative has partnered with @NASA_DEVELOP  on more than a dozen projects since 2008, helping the state model flood and erosion impacts and manage invasive species around Lake Michigan. #SpaceForUS

As cities have locked down due to #COVID19 , satellite data have shown a decrease in nitrogen dioxide, an air pollutant released by human activities. Now, as cities like Wuhan, China are opening back up, satellite data show a rebound in NO2 emissions.

Ready to #LaunchAmerica ? Tomorrow, two astronauts 👨🏻‍🚀👨🏻‍🚀 are launching 🚀 to the @Space_Station  from @NASAKennedy’s historic Launch Complex 39A. @NASA’s Earth Observing-1 satellite captured an image of the launch pad from space.

Certain materials in cities can absorb sunlight in a way that makes cities hot -- creating "urban heat islands.” Things like green roofs can help mitigate some of that heating. For #NASAatHome , we'll show you how to create tiny green birdhouse roofs.

First-of-a-kind maps show how snow on Arctic sea ice changes from month to month. The insulating snow layer is an important part of the sea ice system, affecting how the ice grows and melts.

We've all seen cumulonimbus storm clouds from below, but have you ever stopped to watch from above 🛰️ as they build up in the afternoon? ⛈️

This image of a cumulonimbus over China's Hainan Island was acquired in the afternoon on May 11, 2020, with the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite.

Different environments reflect and absorb heat in different ways. Cities are often warmer than surrounding green space -- a concept called urban heat islands. For #NASAatHome , we'll show you how satellites measure the heat of different environments.

NASA's AIRS instrument maps carbon monoxide (CO) from fires burning in Brazil's Amazon region. This time series ⬇️ shows CO high in the atmosphere over Brazil from Aug. 8-22, 2019. Each "day" in the series is made by averaging three day's-worth of data:

Airborne Nitrogen Dioxide Plummets Over China #NASA 

This decades-long warming trend is the result of increasing greenhouse gases ♨️ in the atmosphere, released by human activities.

Germany may be heading toward its third summer of drought in a row due to high temperatures and sparse precipitation.

2019 was the second hottest ? year and the last decade was the warmest decade on record. The global average temperature was more than 2°F warmer than during the late 19th century.

Visualizing the Warmest August in 136 Years Data via @NASAGISS  #NASA  #climate 

The northeastern U.S. has seen decreased levels of nitrogen dioxide air pollution — a result of #COVID19  activity restrictions. Initial @NASA  satellite data appear to show ~30% lower levels of NO2 in the region in March 2020 compared to the average March.
