Agro-climatic monitoring programs and global food security risks are monitored using MODIS NRT data from 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: Corrected Reflectance True Color and Bands 7-2-1, Land Surface Reflectance bands 1-2-1, Snow Cover, AIRS precipitation (day and night). In Worldview, LANCE imagery can be overlaid with the following data sets from the Socio Economic Data and Applications Center (SEDAC): Flood Hazard Frequency and Distribution (1985 - 2003), Flood Hazard-Mortality Risk and Flood Hazard Economic Risk.
