This animation depicts gridded, daily volumetric water content estimated for the 0-5 cm surface soil layer between March 2017 and August 2020. These soil moisture data constitute the first land product from CYGNSS, a NASA Earth Ventures mission and satellite constellation for ocean surface remote sensing using a technique called GNSS-Reflectometry, and represent a starting point to explore land surface research applications using this promising new technique. The dataset can be accesses from the PO.DAAC Portal at https://doi.org/10.5067/CYGNU-L3SM1 (DOI: 10.5067/CYGNU-L3SM1)

Studying sea level rise today will help us better understand its impact on tomorrow. After living in coastal Virginia and seeing the effects of climate change firsthand, Ben Hamlington is now researching sea level rise at NASA JPL. The launch of the Sentinel-6 Michael Freilich satellite will provide new and better insights about our Earth’s changing ocean.

Our planet is changing. Our ocean is rising. And it affects us all. That’s why a new international satellite will continue the decades-long watch over our global ocean and help us better understand how climate change is reshaping our planet.

Earth’s surface is covered by 70% ocean. Rising seas caused by climate change affect everyone across the globe, from coastal communities to those living inland. Growing up in landlocked Zimbabwe, NASA JPL engineer Shailen Desai was far from the ocean but still experienced its effects on the climate. Now, he is contributing to an international effort to track our rising seas.

For NASA scientist Severine Fournier, studying our planet knows no borders. Our changing ocean affects everyone across the globe. That’s why the new Sentinel-6 Michael Freilich satellite, launching Nov. 10, is a truly international mission that will study our rising seas from space.

Evolution of the NASA Multi-Scale Ultra-High Resolution (MUR) sea surface temperature (SST) anomaly response to Tropical Cyclones Laura and Marco in 2020. It is common to observe trails of cooler water, or cold wakes, along hurricane tracks as a result of wind-induced mixing and turbulence that brings cold waters at depth to the surface. The cold wakes associated with Laura and Marco are clearly observed as waters approximately 2°C cooler from normal across the entire eastern Gulf of Mexico that persisted for several days. (MUR SST DOI: 10.5067/GHGMR-4FJ04).

The QuikSCAT satellite/instrument launched on 19 June 1999 to retrieve ocean surface wind vectors calibrated to 10 meters above the ocean surface and provides 90% global coverage over the ice-free oceans, seas and large lakes when in full operating mode. Shown in this animation is wind speed from the QuikSCAT Level 2B Version 4.1 dataset (DOI: https://doi.org/10.5067/QSX12-L2B41) from 27 October 1999 to 22 November 2009.
