ATom: Measurements from Meteorological Measurement System (MMS), 2016-2018

Description

This dataset contains measurements from the Meteorological Measurement System (MMS) instrument from the four ATom campaigns. MMS is a state-of-the-art instrument for measuring accurate, high resolution in situ airborne state parameters (pressure, temperature, turbulence index, and the 3-dimensional wind vector). These key measurements enable our understanding of atmospheric dynamics, chemistry, and microphysical processes. The MMS is used to investigate atmospheric mesoscale (gravity and mountain lee waves) and microscale (turbulence) phenomena. An accurate characterization of the turbulence phenomenon is important for the understanding of dynamic processes in the atmosphere, such as the behavior of buoyant plumes within cirrus clouds, diffusions of chemical species within wake vortices generated by jet aircraft, and microphysical processes in breaking gravity waves. Accurate temperature and pressure data are needed to evaluate chemical reaction rates as well as to determine accurate mixing ratios. Accurate wind field data establish a detailed relationship with the various constituents and the measured wind also verifies numerical models used to evaluate air mass origin.

34 MMS instrumentation on the DC-8 aircraft during the fourth field campaign in the NASA Convection and Moisture Experiment (CAMEX) series. The MMS Air Motion Sensor System consists of sensors that measure airflow angles such as angle of attack (AOA) and yaw angle, total and static pressure (P_total, Ps), and slow and fast temperature responses (T_fast, T_slow). The fast temperature probe location has been modified recently. The inset picture shows the rear rack with the Data Acquisition System (DAS) and Inertial Navigation System (INS). https://daac.ornl.gov/ATOM/guides/ATom_MMS_Instrument_Data_Fig1.png
