This one’s a gem. We’re working with @USGS to map minerals in the southwest U.S. that can provide new information on Earth’s surface and the effects of climate change using advanced airborne imaging. go.nasa.gov/3M6j0d0

The project will complement data from EMIT – the newest instrument on the @Space_Station that will help us understand how mineral dust affects heating and cooling of the planet.

The ongoing drought in California has cut rice acreage in the Sacramento Valley in half. 🌾 These @NASA_Landsat images from 2021 (left) and 2022 (right) show tens of thousands of acres of farmland that were unplanted in 2022. go.nasa.gov/3rnBlbU

This map shows changes in how plants absorb visible light and reflect infrared light from August 2022 to the year prior. Drought-stressed plants reflect more visible light and less infrared, and satellites can detect this from space. go.nasa.gov/3rnBlbU

The Greenland Ice Sheet is losing mass. Glaciers close to the ice sheet are also losing a significant amount of ice, and at an accelerating rate. go.nasa.gov/3y4UPG6

These maps show where peripheral glaciers have thickened (blue) and thinned (red). Dark red shows where the glaciers have dropped about 1 meter (~3.3 feet) in elevation.

Satellite images offer insight into a storm's intensity. #Landsat 8 passed over Hurricane Ian’s eye as it approached southwest Florida. The eye of a hurricane is a circular zone of fair weather at the storm’s center, surrounded by an eyewall of the strongest winds.

This animation shows the evolution of Ian’s wind field. The strongest winds appear bright yellow, while more moderate winds are orange and bright purple. As it moves northeast, a second, larger eye forms around and eventually envelops the original eye.

🚀🛰#JPSS2 is unbagged and on an aronson table while technicians prepare for launch! This is the 3rd weather satellite in the @JPSSProgram, a @NOAA and @NASA collaboration. Launch is Nov. 1 on a @ULALaunch #AtlasV from @SLDelta30 into a polar orbit.

A data view of Hurricane Ian: This image combines microwave emissions measurements from COWVR and TEMPEST, aboard the @Space_Station. The colors indicate different sections of the storm. White - clouds Green - rain Yellow, red, black - air and water vapor moving swiftly

Here’s a look at the COWVR instrument on the ISS. The rotating reflector collects the microwave emissions from the storm allowing weather forecasters to peer inside the clouds and measure its strength. As the @Space_Station moves, it scans over the storm to produce an image.

At 1:10pm UTC, @NOAA’s GOES-16 satellite acquired this image of the storm with sustained winds of 250 kilometers (155 miles) per hour—making it a major category-4 hurricane and putting it near the threshold of a category-5 storm.
