Remote sensing of the atmosphere by optical, acoustical, or radar means is becoming increasingly important in the meteorological community. Yet those of us in remote-sensing development are frequently asked the question, "How do you know your interpretation of the probing wave interactions with the atmosphere is correct?" Indeed, providing the independent verification of remote sensor performance has always been a challenge.by Freeman F. Hall, Jr.
Synchrontron radiation is currently viewed by scientists in many fields as an ideal source of light for experiments in science and technology. A recent report by the National Academy of Sciences1 states that over the next ten years both construction of new facilities dedicated solely for use as sources of synchrotron radiation and expansion and dedication of existing facilities are required to meet national needs. To respond to this national need for extreme ultraviolet synchrotron radiation facilities, the National Bureau of Standards (NBS) is making available its dedicated Synchrotron Ultraviolet Radiation Facility (SURF) to users in the general scientific community outside NBS.by Lucy Hagan
