Cloud Properties Experiment (CPEX)

Where: Table Mountain, Boulder, Colorado

When: Summer 2018

The Cloud Properties Experiment (CPEX) was 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 was 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 collected data, but future funding would be required and explored for data analysis.

Participants and instrumentation for this activity are:

NOAA ESRL GMD Chuck Long, Kathy Lantz, Allison McComiskey, Gary Hodges, Patrick Disterhoft 3 RadSys Systems (downwelling SW, DNI, DHI, LW, T, RH, P)
