This map displays growing degree days (GDD), created from Aqua and Terra MODIS LST data, for onion crops for August 2017. Onions will grow at a base temperature of 1.6°C (35°F). Here, the darker the shade of blue, the higher the accumulated temperatures over the base temperature of 1.6°C. For example, if the temperature exceeds the base temperature by 4.4° C (40°F) per day for 30 days, the GDD of that area for the month is 1,200. Results from the maps created in this project can be used by decision-makers in the agricultural industry to monitor temperatures and GDDs across the growing season.

These data can help the agriculture sector observe the temperature threshold days for growing crops and can help the energy sector with predicting when the surrounding community may increase the demand for electricity or gas for heating or cooling. Maps from this project provide the ability to observe monthly GDD more efficiently and at a better spatial resolution than data that are currently collected from an in situ network. An example map of GDD for onions for the month of August is shown on the right. A goal of this project is that NOAA’s Northeast Region Climate Services Directorate and Climate Monitoring Branch will distribute these maps to various energy and agriculture industries throughout the region to help the area plan for future agricultural and energy needs.

About the NASA DEVELOP National Program
The DEVELOP National Program is part of NASA’s Applied Sciences Program. Participants from around the country join the DEVELOP program for 10-week terms to apply data acquired by NASA Earth-observing satellites to bridge the gap between science and society. DEVELOP participants work with local, state, and federal partners to create maps and other products in eight focus areas, including Agriculture & Food Security, Disasters, Ecological Forecasting, Energy, Health and Air Quality, Urban Development, Water Resources, and Transportation & Infrastructure.
