The Vertical Atmospheric Structure Trail VAST92 took place from September 28 to October 16, 1992 at the Wehr Technische Dienststelle WTD 52, Oberjettenberg, Germany, in the framework of NATO working group AC243 Panel 4 RSG.8 on atmospheric propagation effects on electro-optical systems. The experiment was designed to quantify the influence of the atmospheric vertical structure variations on infrared propagation and imaging and on lidar means of remotely sensing the variations. The TNO-Physics and Electronics Laboratory participated with a lidar system, meteo and aerosol equipment. The lidar was stationed in the valley. An altimeter and meteo-equipment were mounted on the cable car. Aerosol spectrometers and meteorological equipment were used, including a sonic anemometer and a fast hygrometer to measure turbulence on the mountain. A large part of the data from these instruments is of crucial importance for the evaluation and interpretation of the data obtained by the other participants. In this report, we present an overview of the TNO instrumentation and experiments. A number of data sets have been processed to demonstrate the possibilities of the different instruments. Interpretation of the results is postponed to later reports. This report is also a guide-line for processing the TNO data in conjunction with data from other participants.
