November 1, 2009JPEG
The skies over northwest India were extremely hazy on November 1, 2009, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this image. Scores of fires (locations outlined in red), probably related to agriculture, were puffing small plumes of smoke that coalesced into a thick river of haze to the south. The haze may also contain urban air pollution and dust.

Acquired November 8, 2009, this true-color image shows a cluster of fires, marked by red outlines, burning in northwestern India, not far from the Pakistan border. Haze appears especially thick in Pakistan, and might result from multiple sources.
Acquired October 21, 2009, this true-color image shows a large cluster of fires burning in northwestern India. Red outlines delineate actively burning fires, and many fires produce small smoke plumes.
