Earth: September 2018



How many times have you stepped outside into a surprise rainstorm without an umbrella and wished that weather forecasts were more accurate?


A new NASA-led study helps answer decades-old questions about the role of smoke and human-caused air pollution on clouds and rainfall.


The Copernicus Sentinel-2A satellite takes us over the largest island of the Azores: São Miguel.


A new experimental weather satellite no bigger than a cereal box got an inside look at Hurricane Florence in a test of technology that could influence the future of storm monitoring from space.


A typical desk globe is designed to be a geometric sphere and to rotate smoothly when you spin it. Our actual planet is far less perfect -- in both shape and in rotation.


Hurricane Harvey dumped more than 5 feet (1.5 meters) of water on southeast Texas in late August 2017, making it the wettest recorded hurricane in U.S. history. But after the storm passed, where did all that water go?


NASA's ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) captured new imagery of variations in surface-temperature patterns in Los Angeles County.


The Copernicus Sentinel-1B satellite takes us over Semera in northeast Ethiopia. Semera is a new town with a population of just over 2600 and serves as the capital of the Afar region.

NASA's Global Precipitation Measurement mission or GPM core observatory satellite flew over Tropical Storm Florence on September 7, 2018.


On Sept. 11 at 2:35 a.m. EDT the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite captured an infrared night-time view of Hurricane Florence that provided cloud top temperatures.


The Atlantic basin was relatively quiet for much of August 2018, but September brought a surge in storm activity.


The Copernicus Sentinel-3A satellite takes us over the North Sea, revealing a significant algae bloom covering most of the southern part.


Hurricane Florence became more powerful over the past few days while moving through the central Atlantic Ocean and wind speeds increased from tropical storm force to a Category 3 hurricane.


Typhoon Jebi brought flooding to Japan and NASA's IMERG estimated rainfall over the country and the surrounding region for a one-week period.
