MODIS
Moderate Resolution Imaging Spectroradiometer (MODIS) instruments are aboard NASA’s Terra and Aqua platforms and provide estimates about aerosol optical depth. Terra's orbit is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon.

From MODIS to VIIRS: Continuing the Legacy

The Visible Infrared Imaging Radiometer Suite (VIIRS) will help ensure continuity of Earth observations after the upcoming retirement of the Moderate Resolution Imaging Spectroradiometer (MODIS).
