LANDSAT-D ground segment operations plan, revision A

The basic concept for the utilization of LANDSAT ground processing resources is described. Only the steady state activities that support normal ground processing are addressed. This ground segment operations plan covers all processing of the multispectral scanner and the processing of thematic mapper through data acquisition and payload correction data generation for the LANDSAT 4 mission. The capabilities embedded in the hardware and software elements are presented from an operations viewpoint. The personnel assignments associated with each functional process and the mechanisms available for controlling the overall data flow are identified

Air-Water Gas Transfer

A more complete understanding of the mechanisms involved in the exchange of gases between the atmosphere and the sea is needed if we are to address various environmental issues, and is essential to improved modeling of global climate. This volume contains selected papers from the Third International Symposium on Air-Water Gas Transfer, held at the University of Heidelberg, in Heidelberg, Germany from July 24-27, 1995. The papers are arranged into seven parts: Physical and Chemical Mechanisms, Waves and Turbulence, Breaking Waves and Bubbles, Measuring Technology, Laboratory Measurements and Facilities, Field Measurements, Remote Sensing, and Global Modeling. Emphasis is given to the transfer of carbon dioxide and other radiatively important gases, reflecting current interest in potential global warming. Breaking waves and the bubbles thereby generated play a prominent role in that regard. Also featured are non-invasive measurement technologies, many of which lend themselves to remote sensing applications. Those interested in chemical engineering, fluid mechanics, hydrology, hydraulics, environmental engineering, water quality engineering, climatology, meteorology, and oceanography will find this work a valuable resource
