Visible and near infrared wavelength sensors mounted on operational satellites now in use do not have onboard absolute calibration devices. One means of establishing an in-orbit calibration for a satellite sensor is to make simultaneous measurement of a bright, relatively uniform scene along the satellite view vector from a calibrated instrument on board a high altitude aircraft. Herein, aircraft data were recorded over White Sands, New Mexico at satellite overpass time. Comparison of the coincident aircraft and orbiting satellite data for the visible and near infrared wavelength channels of the NOAA-9 Advanced Very High Resolution Radiometer shows that the calibration of the visible channel was unchanged from prelaunch values, but that the near infrared channel has degraded 6 percent by Aug. 1985. By Oct. 1986 the visible channel had degraded 13 percent and the near infrared channel had degraded 19 percent. Smith, Gilbert R. and Levin, Robert H. and Koyanagi, Robert S. and Wrigley, Robert C.

Since the launch of the first of the Advanced Very High Resolution Radiometers (AVHRRs) in 1978, the data from these instruments has used for a wide range of non-meteorological applications. In this book, the author describes satellite system, AVHRRs, control of the spacecraft, and data- recovery arrangements. The book covers processing of the data to extract useful environmental information. The applications of the data to marine problems, based primarily on the study of sea-surface temperatures from the thermal-infrared channels of the instrument, are considered, as well as the study of vegetation and a whole variety of other land-based and hydrological applications.

Mohamed Larbi Selassi Deputy Director of the National Meteorology, Morocco Welcome address (translated from French) WMO, WCRP, Medias-France and scientific institutions representatives, ladies and gentlemen, to thank WMO and MEDIAS-France, who have honoured us by I want first organizing the two workshops, climate indices in Africa and data assessment for global change research in the Mediterranean region, in Casablanca and I welcome all of you here in Morocco. It is with great pleasure that I open these two workshops on behalf of myself and on behalf of the Direction of the Meteorologie N ationale of Morocco. Climate change is becoming the focus of the international community because of its global scale and unpredictable effects, the numerous impacts it causes, its global feature and the complexity of the solutions that can mitigate its impacts. Global warming and the greenhouse effect became a subject of study at the international level since the United Nations Conference on the human environment that was held in Stockholm in 1972. The research and coordination efforts that have been made in this area have led to an "International Scientific consensus". High level meetings like those held in Toronto in 1988, in Lahaye in 1989 and in Geneva in 1990, did confirm the greenhouse threat and the emergency to treat it.

This is a detailed description of the steps leading from raw signals measured in space, to calibrated comparable long term data sets, to its final form: useful information for user communities. Examples of applications and data validations result from different investigations in the Mediteranean area. An appendix summarizes useful formulas of the evaluation of satellite data.
