Aerodist Measurements and Chart–based Recording. The Aerodist system allowed dynamic slope distances from two ground transponder (or remote) stations to be measured by the master equipment in an aircraft that would fly between the two ground stations. By using these measured slope distances, as well as the known aircraft antenna separation.

[1] Hourly sea level observations measured by five tide gauges at Santa Cruz harbor (Tenerife Island), in the Northeastern Tropical Atlantic, have been merged to build a consistent and almost continuous sea level record starting in Datum continuity was ensured using high precision leveling information. The time series underwent a detailed quality control in order to remove outliers, time.

The Deep Propagating Gravity Wave Experiment (DEEPWAVE) was the first comprehensive measurement program devoted to quantifying the evolution of gravity waves (GWs) arising from sources at lower altitudes as they propagate, interact with mean and other wave motions, and ultimately dissipate from Earth’s surface into the mesosphere and lower thermosphere (MLT).
