Carbon Comes Full Circle

 
   
 

Two investigations—one using field campaigns, one using commercial smallsat data—are helping put the cycle in carbon cycle.

 
   
 

Taking a Deep Dive for Ocean Carbon Data

 
   
 

The NASA-led Export Processes in the Ocean from Remote Sensing (EXPORTS) project investigates how organic carbon is biologically produced, processed, and stored in the depths of the ocean.

 
   
 

NASA Counts 9.9 billion Trees in Africa with the help of Commercial Satellite Data

 
   
 

Results from this research establish a framework for mapping carbon stocks at the level of individual trees at a sub-continental scale, help improve ecosystem models, and provide a tool for restoration efforts.

 
   
   
    
 

April 22 is the global Earth Day celebration and NASA has you covered. NASA maintains one of the largest archives of Earth science data on the planet—all of which are fully and openly available. Start your explorations today!

Tropospheric Ozone

Ozone is a two-edged sword: beneficial in Earth’s stratosphere, but harmful in the troposphere. Dr. Owen Cooper’s work using NASA Earth science data is shedding new light on the current—and future—state of this critical atmospheric component.

 Mapping Global Agriculture

The 30-meter Landsat-Derived Global Rainfed and Irrigated-Cropland Product (LGRIP) maps the world’s agriculture into rainfed and irrigated croplands.

 
   
 ABoVE Dataset for Alaska Vegetation

The Alder Shrub Cover and Soil Properties, Alaska, 2019, NASA Arctic Boreal Vulnerability Experiment (ABoVE) dataset provides measurements for sites in interior Alaska along the James W. Dalton Highway.

 
   
 Tracking Global Salt Marsh Changes

A NASA Carbon Monitoring System (CMS) dataset provides global salt marsh change at a 30-meter spatial resolution, including loss and gain for five-year periods from 2000-2019.

 
   
 Updated Sea Surface Salinity Data

Sea surface salinity (SSS) is a vital component of ocean circulation. Updated SSS data products created from Soil Moisture Active Passive (SMAP) data fill a data need identified in the 2020 Satellite Needs Working Group survey.

 
   
 Jupyter Notebook for Plotting California Storms

A Jupyter Notebook shows how to use Python to plot sea surface salinity anomalies over the ocean and precipitation over land to visualize the impact of recent severe storms over California.

 
   
 WindSat TOA Dataset

A new global WindSat Top of the Atmosphere (TOA) Brightness Temperature dataset from Remote Sensing Systems (RSS) is available. The WindSat Polarimetric Radiometer was designed to measure ocean surface wind vectors from space.

 
   
 New RAMSES II Dataset

A Level 2 Retrieval Algorithm for Microwave Sounders in Earth Science (RAMSES II) dataset provides the retrieval of all-sky temperature and humidity profiles in the presence of clouds.

 
   
 Sentinel-5 Precursor (S5P) Full Mission Reprocessed Datasets

Full mission data of variables derived from Tropospheric Monitoring Instrument (TROPOMI) observations for all Level 1B products and Level 2 methane, nitrogen dioxide, and aerosol layer height products are available.

 
   
 Tracking Global Migration Patterns

The new Groundswell Spatial Population and Migration Projections dataset helps show how slow-onset climate change might affect internal migration in low- to middle-income countries in the coming decades.

 
   
 Global Natural Resource Protection and Child Health Indicators

The Natural Resource Protection Indicator (NRPI) is based on biomes under protected status. The Child Health Indicator (CHI) is a composite index derived from scores for access to at least basic water and sanitation, along with child mortality.

 
   
 SAR Products Available for Recent Earthquakes

Synthetic Aperture Radar (SAR) data products acquired over the area of the recent Turkey/Syria earthquakes are now freely available from the Japan Aerospace Exploration Agency.
