Observations/
Our lab coducts fundamental research in to the transport of mass, momentum, and heat in the atmospheric boundary layer. We use micrometerological proinciples to observe the surface to atmosphere interactions over complex terrains. We particularly focus on urban and coastal urban boundary layers. The work helps us to understand and develop physics based models to represent these complex environments. We have permanent facilities in NYC and alos have capacity to conduct these measurements anywhere required.
Coastal-Rural-Urban Gradient:
The spectral analysis exhibits the presence of vastly different flow regimes along the coastal-rural-urban transect. The coastal site is dominated by the sea breeze effect that dictates the transport of heat and momentum. The urban and rural sites are influenced by local land cover characteristics that impact the hygro-thermal climate.
Urban mixed-layer turbulence: A key part of our lab’ work is multi-scale urban observations- from indoor to city-scale. We use traditional boundary layer techniques to study surface layer and mixed layer characteristics as well as work on developing cost-effective sesnors for understanding indoor/outddor airquality.
We focus on understanding the complex boundary layer characteristics over the urban and coastal urban regions. We employ profilers- cielometer, microwave radiometer, and Doppler lidar - to study the transport of mass, momentum, and heat. We have an active campaign in NYC and in Summer 2022, deployed them in Houston, Texas.
Our lab is also involved in developing sesnors to study indoor/outdoor air quality. We use open source platforms and cost-effective sensors to develop instrumentation platform that is capable of sensing and communicating the data.
