Measurements from energy-detecting instruments on satellites provide a way to monitor vegetation health, drought, soil saturation, moisture and thermal conditions, fire risk, greenness of vegetation cover, vegetation fraction, leaf area index, start/end of the growing season, and crop and pasture productivity. 

Where do these data come from?

Data and images are derived from the radiance (type and amount of energy) observed by the VIIRS instrument onboard the Soumi-NPP satellite. VIIRS stands for Visible Infrared Imaging Radiometer Suite: the instrument is on the Soumi-NPP satellite.

How to

What can I do with these data?

  • Compare various datasets to explore recent and current growing conditions across 245 countries or regions around the world.
    • See how and where vegetation health has improved or declined over the last week
    • Look for areas of increased drought risk
    • Identify areas with an enhanced risk of malaria
