9.1 Fundamentals

Table 9-1 provides an overview of the upper-air monitoring systems included in this guidance. Necessary details describing the operation of each of the monitoring platforms [Radiosonde (9.1.2), Doppler Sodar (9.1.3), Radar Wind Profiler (9.1.4), and RASS (9.1.5)] is preceded by a description of the various meteorological variables that are measured by, or derived from measurements obtained with these platforms
