Changing Everglades

This image depicts the coastline along the Everglades National Park. It was acquired by NASA’s Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) instrument, flown aboard a Gulfstream III on June 15, 2009. In this RGB image, red portrays microwaves that have undergone double bounce from water to tree, green portrays microwaves that have scattered off vegetation, and blue portrays microwaves that have bounced off a surface. Hurricane damage to the mangrove forest structure is visible along Florida's coast. UAVSAR data is available from the NASA Alaska Satellite Facility (ASF) Distributed Active Archive Center (DAAC).

Lake Shasta, California

Shasta Lake in northern California is the state’s largest reservoir. Impacts of continuing drought in the western US is seen in the two NASA Terra Advanced Spaceborne Thermal Emission Radiometer (ASTER) images acquired 9 years apart. The images were acquired September 9, 2005 and September 2, 2014. ASTER data is available through the NASA Land Processes DAAC (LP DAAC).

Snow Pack in the Sierra Nevada

These two true-color Moderate Resolution Imaging Spectroradiometer (MODIS) Aqua satellite images show snowpack in the Sierra Nevada. The image on the left was acquired on March 27, 2010 (last year with average snow cover). The image on the right was acquired on March 29, 2015. Significantly lower snowpack is visible. MODIS Level-1 radiance data is available from the Level-1 Atmosphere Archive and Distribution System (LAADS) DAAC.

March 2014 East Coast Snowstorm

One of the first storms observed by the joint NASA/Japan Aerospace Exploration Agency (JAXA) Global Precipitation Measurement (GPM) Mission Core Observatory on March 17, 2014, in the eastern United States. This image shows a full range of precipitation - from rain to snow. The GPM Mission was launched on February 27, 2014. Find out more information about GPM and NASA’s precipitation missions.

Both GPM and TRMM data are available through the NASA Goddard Earth Science Data and Information Services Center (GES DISC).

Global Food Security Support Analysis Data (GFSAD)

This NASA Making Earth System Data Records for Use in Research (MEaSUREs) Global Food Security Support Analysis Data (GFSAD) at 30m satellite image shows a portion of the U.S.-Mexico border in southern California. The border is the sharp east-west line in the center of the photo, and the Mexican city of Mexicali is the gray/purple area just south of the border. Areas colored bright green are areas of healthy and active agriculture, while brown marks desert or non-cultivated lands. Find out more information about the GFSAD@30 Project.

Carbon Fluxes from Global Agricultural Production and Consumption, 2009

This NASA Carbon Monitoring System (CMS) data set provides global estimates of carbon fluxes associate with annual crop net primary production (NPP) and harvested biomass, annual uptake and release by humans and livestock, and the total annual estimate of net carbon exchange (NCE) derived from these carbon fluxes. NCE estimates are for the combined crop plant harvest and consumption/expiration of fodder by livestock and of food by humans. All CMS products are available through the NASA Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC).

Percent Tree Cover, Washington, DC

This Web-Enabled Landsat Data (WELD) Land Cover Land Use Change (LCLUC) image shows percent tree cover over 5 annual growing seasons - green indicates a larger percentage, while brown denotes a smaller percentage of tree canopy cover. The WELD project is funded by the National Aeronautics and Space Administration (NASA) and represents a collaboration between the United States Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center and the South Dakota State University Geospatial Sciences Center of Excellence (GSCE). WELD systematically generates 30 m composited Landsat Enhanced Thematic Mapper Plus (ETM+) mosaics of the United States and Alaska from 2002 – 2012 to provide consistent data for deriving land cover, geophysical, biophysical products for regional assessments of surface dynamics for effective studying of Earth system functioning. WELD data is distributed by the NASA Land Processes DAAC (LP DAAC).
