The MODIS sensors aboard the twin satellites Aqua and Terra provide global coverage of earth’s surface every 1 to 2 days. MODIS’s spatial, spectral, and temporal resolution allow for imagery to be utilized for regional monitoring of vegetation, land surface temperature, and the environment. MODIS data is available for Terra (daily, 8 day, or 16 day composites), Aqua (daily, 8 day, or 16 day composites), and composite of Terra/Aqua 16 day using at surface reflectance data.

Enhanced Vegetation Index (EVI) provides information on vegetation growth and productivity. Effects due to climate, weather, fire, water, and vegetation and crop management practices can be assessed through developing and visualizing maps, time series, and anomalies of EVI.

EVI is calculated using the Blue, Red, and Near infrared (NIR) bands following the equation EVI = 2.5 * (NIR – Red) / (NIR + 6 * Red – 7.5 * Blue + 1). The Blue band is used to correct Red band values for atmospheric influences and for effects of the underlying soil (Lie and Huete, 1995). EVI does not saturate as quickly in conditions of high leaf area index or biomass. EVI ranges between -1 and 1 where values above 0.5 represent conditions of high vegetation vigor.

Bands Used:
Near Infrared (NIR): 0.841-0.876 μm
Red: 0.620-0.670 μm
Blue: 0.459-0.479 μm
