Aerosols are collections of suspended solid or liquid particles in the gaseous atmosphere, such as dust, sulfates and nitrate molecules, black and organic carbon, sea salt ocean droplets that can absorb and scatter solar radiation, act as nuclei in forming liquid rain and ice droplets in clouds, influence local convective storms, tropical cyclones and can destabilize the planetary boundary layer height (PBLH). Aerosol observations are required on an hourly basis to follow the changes in the PBLH. Multiple satellite-based instruments are becoming available to observe aerosol distributions. However, they still mostly measure total-column quantities or vertical profiles with low-resolution near the ground, limited frequent coverage leading to a difficult task of untangling the Planetary Boundary Layer information from the column measurement. We have built a multi-sensor ground-based observatory network of ceilometer instruments distributed over the US which provide near real-time, streaming of high-resolution aerosol profiles up to 15km from the ground. We propose to use a novel tensor decomposition method to analyze the stream of aerosol profiles. The streaming tensor decomposition method enables one to analyze Mixed Boundary Layer Height (MBLH) acquired from our observation network in near real time and over long time data archive records. The tensor has been formed using 3 dimensions, a station site location, time of day and day with a value of the MBLH derived from a machine learning holistic edge detection algorithm. The normalized output results from the tensor decomposition method consist of high order tensors components with coefficients analogous to eigenvalues. We will show the time dependence of the dominant components of MBLH. These dominant components will show the correlations of MBLH over 24 hours over multiple regions. We can also use tensor decomposition to analyze climate data records of MBLH (monthly, seasonal or annual).
