Net Ecosystem Exchange

The image shows modeled terrestrial ecosystems-atmosphere net carbon exchange over the U.S. Midwest in July 2018. Wheat grows near Oklahoma City from winter to late spring, and the area acts as a net carbon source (shaded brown) during summer after the crops have been harvested.

The CASA Biogeochemical Model

The data that produced this image were simulated by the Carnegie Ames Stanford Approach (CASA) biogeochemical model. Net carbon exchange between the terrestrial ecosystem and atmosphere west of Memphis indicates a carbon sink (green and blue areas) during July as rice and soybeans grow.

ACCESS NASA EARTH SCIENCE DATA

NASA's data policy ensures that all NASA data are available fully, openly, and without restrictions. Here's what this means to you.

Heavy Rains Over Kyushu Island, Japan

Precipitation Rate on 5 July 2020 from IMERG.

Using Satellites to Measure the Size and Shape of Mangroves

Researchers use remote sensing to measure mangrove forest extent and tree height to inform sustainable management of these ecosystems.

User Profile: Dr. David Lagomasino

Coastal ecosystems are some of Earth’s most biologically diverse environments, especially coastal mangrove forests. Dr. Lagomasino uses Earth observing data to study these vital biomes.

New Imagery and Functionality Available in NASA Worldview

New VIIRS imagery from NOAA-20 along with new ways to evaluate and select imagery layers make NASA Worldview more useful than ever.

Improving Hurricane Forecasts with Near Real-Time Imagery and Data

Scientists at NASA's Short-Term Prediction Research and Transition (SPoRT) project use near real-time data to help the operational weather community with hurricane forecasting.

Sensing Invasive Species From Space

Invasive species cost the U.S. economy approximately $120 billion a year and disrupt the dynamics of ecosystems. Researchers are increasingly using remote sensing to map where invasive species are and where they could spread in order to minimize their damage.

NASA SEDAC Application Puts Current Global COVID-19 Data at your Fingertips

A new global mapping tool shows the number of people affected by the COVID-19 pandemic down to the U.S.-county level, and provides data on age and sex categories that can help identify populations most at risk.

Data Chat: Katie Baynes

For NASA EOSDIS System Architect Katie Baynes, having NASA Earth observing data in the commercial cloud will foster not only a new community of data users, but also new communal ways of using these data.

New Dataset of Greenland Ice Sheet DEMs Available at NASA’s PO.DAAC

A dataset with digital elevation models (DEMs) of the Greenland Ice Sheet is the latest release from NASA’s Oceans Melting Greenland (OMG) mission.

Daily Daymet Data mean More Meteorological Metrics

The Daymet data collection at NASA’s ORNL DAAC provides daily meteorological data for the entire North American continent spanning 1980 to 2019 (and counting).
