In southern California, the combined ports of Los Angeles and Long Beach account for 33% of the nation’s containerized imports. In early March, a long-lasting labor dispute between the longshoremen’s union and shipowners came to an end, and the large backlog of waiting cargo ships was being slowly unloaded.

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is an imaging
instrument onboard Terra, the flagship satellite of NASA's Earth Observing System
(EOS) launched in December 1999.
ASTER is a cooperative effort between NASA, Japan's Ministry of Economy, Trade
and Industry (METI), and Japan Space Systems
(J-spacesystems). ASTER data is used to create detailed maps of land surface temperature, reflectance,
and elevation. The coordinated system of EOS satellites, including Terra, is a major component
of NASA's Science Mission Directorate and the
Earth Science Division.
The goal of NASA Earth Science is to develop a scientific understanding of the Earth as an
integrated system, its response to change, and to better predict variability and trends in climate,
weather, and natural hazards.
