Mesoscale and Microscale Meteorology (MMM)

MMM investigates the basic physical processes that govern the weather: how the atmosphere and Earth's surface receive incoming radiation, scatter and absorb it, and retransmit it; how weather and climate are affected by terrain and the characteristics of soil and vegetation; how severe storm systems develop and die; and how precipitation processes occur.

MMM provides research services to the community in four areas. These services include: (1) the development and maintenance of several models; (2) the development of instrumentation; (3) the development of software for analysis of data collected by NCAR and other facilities; and (4) the organization, leadership, and/or participation in field campaigns. We would appreciate input on your use of and your suggested improvements to these research services provided by MMM.

6. MMM Instrumentation

Over the past several years, a number of instruments have been developed by MMM or in collaboration with other divisions, universities or agencies. These instruments are generally developed to advance the research goals of specific scientists, but once operational, they either become part of the overall suite of instruments available through NCAR or remain available through direct collaboration with the principal investigator who developed the instrument.

Among the instruments developed are:

Multi-angle Spectrometer Probe

Intermittent Sampler

Video Ice Particle Sampler

Balloon-borne Ice Crystal Replicator

2D-charge Instrument

Airborne Infrared (IR) Video Camera.

Do you have an interest in using any of these instruments in the future?
