Heber Valley, Utah
What's New?: 

CFACT science and field campaign planning meeting, October 22, 2021 (Friday) from 8:30 am to 2:30 pm US Mountain Time. The primary purpose of the meeting is to review and discuss detailed plans for the field campaign in January and February 2022 and related science missions. The meeting will be virtual on zoom.

Project Description: 

Observations, Modeling, and Prediction of Cold Fog

CFACT  is a field campaign and science project sponsored by the National Science Foundation (NSF) that investigates cold fog formation in mountain valleys.  The overarching goals of the CFACT project are to 1) investigate cold fog development and environment conditions in complex terrain with the latest observation technology, 2) improve microphysical parameterizations and visibility algorithms used in numerical weather prediction (NWP) models, and 3) develop data-assimilation and analysis methods for current and next-generation (e.g., sub-kilometer scale) NWP models. 

The CFACT field campaign will be conducted in Heber Valley, Utah, during January and February 2022, with the support from the NSF Lower Atmospheric Observing Facilities (LAOF), managed by NCAR’s Earth Observing Laboratory (EOL). The deployment of a network of ground-based in-situ instruments and remote sensing platforms will help to obtain comprehensive measurements of thermodynamic profiling, cloud microphysics, physical and chemical properties of aerosols, and dynamics of the environment. Comprehensive data analysis, data assimilation, modeling, verification and validation, and predictability studies will be conducted following the field campaign.
