... agencies, representatives of foreign governments and foreign scientific users will find its contents useful as they plan their own WRC positions. This report identifies and discusses only those agenda items relevant to radio astronomers and Earth remote-sensing researchers and that could impact them.

... Recommendation: Unwanted emissions due to new radar allocations in the 3-50 MHz range should be low enough to meet the levels of Recommendation ITU-R RA.769 in the Radio Astronomy Service bands at 13.36-13.41, 25.56 25.67, and 37.50-38.25 MHz. 1.18 To consider extending the existing primary and Recommendation: Second harmonic radiation secondary radiodetermination-satellite service emissions into the 4800-5000 MHz band should be (space-to-Earth)

... radiocommunication frequencies has become a key means of understanding the effects of changes in both the natural and artificial environment, and of providing information for effective decision making and resource management in many areas of society and life. In addition, Earth science and observation technology have economic benefits, both in job creation and in early warning of potentially disastrous and disruptive situations.
