Cloud Streets

The linear rows of clouds extending off the mainland into the Sea of Okhotsk are called “cloud streets,” and form when cold air blows off land and over the open sea. As the temperature drops, water freezes into tiny clouds, which arrange into rows in line with the wind direction.

MODIS Corrected Reflectance Imagery

This corrected reflectance (true color) Moderate Resolution Imaging Spectroradiometer (MODIS) image uses MODIS Level 1B data in a combination of wavelengths similar to what the human eye sees. These data are available at NASA’s Level 1 and Atmosphere Archive and Distribution System (LAADS) Distributed Active Archive Center (DAAC).


NASA's data policy ensures that all NASA data are available fully, openly, and without restrictions. Here's what this means to you.


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.
