Highlights will be written for high-level accomplishments and published journal articles of ASR research. Each PI should submit one highlight per fiscal year.

Recent Highlights
Objective determination of synoptic states
4 November 2018
Mechem, David B.
Supported by:
Research area: Cloud Distributions/Characterizations
Studies that explore aerosol–cloud–precipitation interactions must account for the different environments in which these processes occur. This effort demonstrates an objective approach based on self-organizing maps (SOMs) to classify the synoptic state (meteorological environment) that is sufficiently general to be applied to any geographical area.
Mean precipitation change from a deepening troposphere
3 November 2018
Romps, David
Supported by:
Research area: Radiation Processes
Why does the equilibrated global precipitation rate increase at roughly 2% per K in all global climate models? Despite the ubiquity of this result, we have not yet had an explanation for it.
Molecular and physical characteristics of aerosol at Pico Mountain Observatory in the Azores
23 October 2018
Mazzoleni, Lynn R; Mazzoleni, Claudio
Supported by:
Research area: Aerosol Processes
Oxidation plays an important role in governing the interactions of organic aerosol with clouds and atmospheric heterogeneous chemical reactions. To learn more about the chemistry of long-range-transported free tropospheric aerosol, we studied the molecular composition of organic aerosol collected at the Pico Mountain Observatory in the Azores.
Time scales in study of turbulent entrainment-mixing processes
23 October 2018
Liu, Yangang
Supported by:
Research area: Cloud Processes
Different microphysical time scales, including droplet evaporation time, phase relaxation time, and reaction time, have been used in investigation of turbulent entrainment-mixing processes and their effects on cloud microphysical properties. This study addresses the outstanding question of which is the proper microphysical time scale and reconciles the differences.
Different regimes and active regions of aerosol indirect effects
23 October 2018
Liu, Yangang
Supported by:
Research area: Cloud-Aerosol-Precipitation Interactions
Different regimes of aerosol indirect effects and the active regions over the global ocean are studied and identified by analyzing long-term satellite measurements of aerosol and cloud properties.
