NSF project on mixed phase clouds

Using airborne in-situ observations to probe the microphysical and macrophysical properties of mixed-phase clouds

Extensive cloud coverage has been observed from satellite images in polar regions, particularly over the Southern Ocean. Three types of clouds - ice, liquid and mixed-phase - have significantly different radiative forcing on Earth's surface. To provide more accurate assessment of the future climate, one would need to improve the simulations of these clouds in global climate models (GCMs).

My team uses airborne, in-situ observations on the scales of hundreds of meters, to evaluate and improve the GCM simulations, and to examine the impacts of global warming and anthropogenic emissions on clouds in the future.


Cloud phase identification method and quality control of VCSEL hydrometer water vapor data in NSF field campaigns

In the American Geophysical Union (AGU) Fall 2018 meeting, I introduced the method we used to identify three types of clouds - ice, liquid, and mixed phase. Data from two flight campaigns from the National Science Foundation were analyzed. 


Data download for VCSEL QA/QC water vapor data are available in 1-Hz and 25-Hz resolutions. 


Please contact PI Minghui Diao for more details about the cloud phase identification method, and for the most recent QA/QC of water vapor data in NSF SOCRATES campaign.
