Plug in your headphones and listen to some science! The latest episode of the USGS podcast Eyes on Earth is out and features data from the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) Mission distributed by NASA’s Land Processes Distributed Active Archive Center (LP DAAC).
Madeleine Pascolini-Campbell from NASA’s Jet Propulsion Laboratory at the California Institute of Technology, and Natasha Stavros from the Earth Lab Analytics Hub at the University of Colorado Boulder discuss their use of ECOSTRESS data in predicting spatial patterns of burn severity for recent California wildfires.

New S-NPP NASA VIIRS Vegetation Indices Data Products Available!New S-NPP NASA VIIRS Vegetation Indices Data Products Available! The Suomi National Polar-orbiting Partnership (S-NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Vegetation Indices data products (VNP13s), produced by NASA, are now available from the Land Processes Distributed Active Archive Center (LP DAAC). These 16-day and monthly data products provide global vegetation metrics at 500 meter, 1 kilometer, and 5,600 meter spatial resolutions. These data can support research on phenology and change detection and can be used as a parameter for vegetation models. The imagery below shows the Normalized Difference Vegetation Index (NDVI) for portions of Romania, including the Carpathian Mountains, and surrounding countries. As the months transition from February to June the region experiences vegetation greenup, as indicated by higher NDVI values. Learn more about this data:http://bit.ly/2K20qpx

Snowpack in the Sierra Nevada Mountain Range (2001-2018)Snowpack in the Sierra Nevada Mountain Range (2001-2018) NASA’s Terra Moderate Resolution Imaging Spectroradiometer (MODIS) satellite sensor can be used to observe large-scale changes that have occurred around the world. The joint NASA NOAA Suomi National Polar-Orbiting Partnership (S-NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) satellite sensor was launched in 2011. The new VIIRS data products, created by NASA, provide a continuation of MODIS heritage and enable the study of drought and water availability over time. This data animation shows Terra MODIS and S-NPP NASA VIIRS observations of the snowpack on the Sierra Nevada mountain range from 2001 to 2018. The melt from this snowpack provides California with 30 percent of their fresh water during years with average rainfall. The California Department of Water Resources measures the amount of snowpack in the mountains every year on April 1, to provide consistent data and to study the size of the snowpack. Notice how in the drought years, for example 2003 and 2015, the snowpack is smaller in size than it is during the wetter years, like 2005 and 2017. Lesser amounts of snowpack can be problematic during times of drought, as water resources for California residents can be limited.
