Agro-climatic monitoring programs and global food security risks are monitored using Moderate Resolution Imaging Spectroradiometer (MODIS) near real-time (NRT) data from NASA's Land, Atmosphere Near real-time Capability for EOS (LANCE). There are several global/regional scale systems in place that report on drought and food shortages including the USAID Famine Early Warning Systems Network (FEWS NET).
Potentially useful data sets: MODIS Corrected Reflectance True Color and Bands 7-2-1, MODIS Land Surface Reflectance bands 1-2-1, MODIS Snow Cover, Atmospheric Infrared Sounder (AIRS) precipitation (day and night). In Worldview, LANCE imagery can be overlaid with the following data sets from NASA's Socioeconomic Data and Applications Center (SEDAC): Flood Hazard Frequency and Distribution (1985 - 2003), Flood Hazard-Mortality Risk and Flood Hazard Economic Risk.
