Pollution Over New Delhi

This image from the Multi-angle Imaging SpectroRadiometer’s (MISR's) vertical viewing camera shows New Delhi under a thick haze. The towering Himalayas stretching across the north (swath displayed horizontally) prevent pollutants from blowing northward.

Sensing Aerosol Optical Depth

This image shows aerosol optical depth from 0 (dark blue) to 1.0 (red), and measures the abundance of aerosols. Optical depths for the area around New Delhi have not been calculated because the haze is so thick that the algorithm classified the area as a cloud.


The Earth Observing System Data and Information System is a key core capability in NASA’s Earth Science Data Systems Program. It provides end-to-end capabilities for managing NASA’s Earth science data from various sources—satellites, aircraft, field measurements, and various other programs.
