GIOVANNI

Giovanni is a Web-based application developed by the GES DISC that provides a simple and intuitive way to visualize, analyze, and access vast amounts of Earth science remote sensing data without having to download the data.

Giovanni is comprised of a number of interfaces, called instances, each tailored to meet the needs of different Earth science research communities. To access a Giovanni instance, click on one of the four categories below.

Atmospheric Instances: A-Train along CloudSat Track; Aerosol Optical Thickness Measurement and Model Comparison Daily and Monthly; Aqua/AIRS Global Daily and Monthly; Aura High Resolution Dynamics Limb Sounder (HIRDLS); Aura Microwave Limb Sounder (MLS); Aura OMI Level 3 and Level 2G; MISR Daily and Monthly; Modern Era Retrospective-Analysis for Research and Applications (MERRA) 3D Monthly and 2D Monthly; MODIS Terra and Aqua Daily and Monthly; Earth Probe and Nimbus-7 TOMS; Upper Atmosphere Research Satellite (UARS) Halogen Occultation Experiment (HALOE)
Environmental Instances: Agriculture; Air Quality; Northern Eurasia Earth Science Partnership Initiative (NEESPI) Daily and Monthly
Ocean Instances: Ocean Color Radiometry (SeaWiFS, MODIS, and derived and model products); Ocean Model Daily and Monthly.
