Knowing the precise location of a satellite in space is critical for determining sea surface height and, through this, the rate of global mean sea level rise. For more than 28 years, a series of satellite ocean altimetry missions has compiled a record of sea surface height using the same global observational ground track. Starting with the Topographic Experiment (TOPEX)/Poseidon mission (operational 1992 to 2006) and continuing with the Jason-1, Ocean Surface Topography Mission (OSTM)/Jason-2, and Jason-3 series of satellites (operational 2001 to present), this consistent ocean altimetry data record continues with the launch of the Sentinel-6 Michael Freilich satellite. The result will be a more than 30-year time-series of satellite-acquired sea surface height data.
Join us for an introduction to NASA SEDAC's Global COVID-19 Viewer - a map-based tool for understanding the spread of the Coronavirus and underlying risk factors. We will learn about its development and then conduct a live demonstration of the viewer focusing on current hotspots, interesting trends, and an exploration of the risk factors.

A new dataset from the North American Carbon Program (NACP) provides gridded estimates of methane (CH4) emissions from dairies in California at an approximately 10 km x 10 km resolution for the year 2019. The mapped sources of dairy CH4 emissions are enteric fermentation and manure management reported in gigagrams per year (Gg/yr).

Fifteen years ago Hurricane Katrina caused severe damage to communities on the Gulf Coast of the United States. The 2020 Atlantic hurricane season has been very active already, with 13 named storms as of August 28, 2020. NASA data and tools can be used to track the movement and development of severe storms, and aid in assessing post-storm impacts. Learn more about NASA tropical storm resources in the new Cyclones Data Pathfinder.
