Cloud Properties Experiment (CPEX)

Where: Table Mountain, Golden, Colorado

When: Summer 2018

The Cloud Properties Experiment (CPEX) will be conducted at the Table Mountain Facility beginning in the summer 2018. This research site is located at 40.125°N and 105.240°W.

The primary purpose of this experiment is to evaluate instrumentation for cloud properties, especially those that may be useful additions to the SURFRAD (Surface Radiation) Network, and secondly to augment a data set for a cloud forecasting study. This campaign will collect data, but future funding will be required and explored for data analysis.

Participants and instrumentation for this activity are:
