Understanding Changes in Cloud Phase Partitioning in Mixed-phase Clouds: an Arctic Case Study

Aug 22, 2016 Funded By: ARM

“A low cloud of water and ice – in Barrow, Alaska, how nice. Its structure was measured with ease – but why did the ice phase decrease?” For a springtime low-level mixed-phase stratiform cloud case from Barrow, Alaska, a unique combination of instruments and retrieval methods is combined with multiple modeling perspectives to determine key processes [...]

Towards Retrieving Critical Relative Humidity from Ground-based Remote-sensing Observations

Aug 16, 2016 Funded By: ARM

In a Global Circulation Model (GCM), cloud should form before the grid-box-mean state becomes saturated. Therefore, assumptions about sub-grid variability in temperature and water vapour are necessary, which are typically combined in the critical relative humidity (RHcrit), the relative humidity at which cloud forms a sub-saturated GCM grid box.

MAGIC Ship-based Observations Help Validate Satellite Microwave Liquid Water Path

Aug 04, 2016 Funded By: ARM ASR

Satellite-based passive microwave (MW) liquid water path (LWP) is a fundamental quantity for climate studies, climate model validation, and validation of satellite visible/near-infrared retrievals over the oceans. Unfortunately, the lack of independent observations has prevented the evaluation of MW LWP, and thus the accuracy of satellite MW-derived LWP remains uncertain. The ship deployment of the [...]

The Python ARM Radar Toolkit, the World's Leading Interactive Radar Toolkit

Aug 04, 2016 Funded By: ARM

Weather radars provide an abundant source of data related to the conditions present in the atmosphere. The Python ARM Radar Toolkit (Py-ART) allows scientists to effectively work with this data and extract scientific insights from these large data sets. Py-ART is used for analysis of weather radar data using established routines available in the [...]
