Fueled by a heatwave and prolonged drought, fires continue to burn in the Iberá National Park in northeastern Argentina.
The fires began in late December 2022 and were still ablaze when #Landsat 9 took these images on Feb. 19, 2023. go.nasa.gov/41efMuW

Happy Mardi Gras! 💜💛💚
During Mardi Gras season in 2012, the Mississippi River broke through its eastern bank and created a new channel to the Gulf of Mexico, the Mardi Gras Pass. #Landsat 8 recently captured this image of the pass.

Ice extent jumped to 21 percent in early February in response to a cold snap. But since then, it has declined. Maximum ice cover is usually between mid-February and early March.
Great Lakes Low on Ice
This winter, ice cover in the basin has hovered at unusually low levels.go.nasa.gov
The Great Lakes have been unusually ice-free this winter. In this image from Feb. 13, ice cover on the lake was 7 percent – the lowest ice cover measured on this date of any year since 1973 when satellite-based record keeping began.

Scientists at the University of Utah studied how snow worsens temperature inversions and air quality.
They found that the chance that air pollution would exceed national standards increased from about 5% to 22% when there was snow on the ground.

The air in Salt Lake City, Utah is often among the most polluted in the U.S.
Snow cover increases the chance of temperature inversions – when warm air acts like a lid, trapping pollutants near the surface, new research finds. go.nasa.gov/3xqvkOA

Snow and Haze in Utah
Snowy surfaces increase the chance of temperature inversions, which contribute to air quality problems in the Salt Lake City area.go.nasa.gov
The Salt Lake City area was covered in snow on Feb. 2, 2023, when @nasa’s Aqua satellite took this image.
At the time, @EPA data showed the air quality was above 100 on the air quality index, making it unhealthy for sensitive groups.

Today's rocket launches are part of an effort to study Earth's mesosphere, the layer of the atmosphere about 31 to 53 miles (50-85km) in altitude. 🚀☁️
The mesosphere is where meteors often burn up. It has its own chemistry and winds, and is where noctilucent clouds form!

2020 saw a record-breaking rise in methane, a potent greenhouse gas. The increase was driven by a combination of warm, wet weather in the Northern Hemisphere and the COVID-19 lockdowns.
Why Methane Surged in 2020
Warm, wet weather in the Northern Hemisphere combined with COVID-19 lockdowns pushed the potent greenhouse gas to record levels.go.nasa.gov
A decrease of nitrogen oxides (NOx) pollution during the COVID-19 lockdowns indirectly slowed the removal of methane from the atmosphere.
NOx serves as an atmospheric “detergent” by reacting with methane and removing it from the atmosphere.

A series of storms brought lots of precipitation to California, helping replenish snowpack and reservoirs.
But was it enough to reverse a decades-long decline in groundwater? It’s unlikely, according to @nasagoddard research.

Reservoirs Rise, but Groundwater Woes Remain
The water delivered by winter storms in 2022-2023 is likely insufficient to reverse the longer-term depletion of California’s groundwater.go.nasa.gov
This chart shows an overall downward trend in terrestrial water storage (dark blue).
The other lines show why this is happening – groundwater (light blue) is sharply decreasing. Data are from @nasa’s GRACE and GRACE-FO satellites.
