Indiana Flux Study (INFlux)

Where: Indianapolis, Indiana

When: Spring 2013 - 2017

The Indianapolis Flux Study (INFlux) is National Institutes for Standards and Technology (NIST) led effort with partners from Pen State University, NOAA ESRL GMD (Global Monitoring Division) and CSD. The primary objective of the experiment is to develop and evaluate methods for measurement and modeling of greenhouse gas fluxes from urban environments. The study will use distributed tower measurements and periodic aircraft sampling of greenhouse gases and dynamics to accomplish goals.

CSD will deploy scanning Doppler lidar instruments to the Indianapolis metro area. The HALO Photonics lidar installation occurs in the Spring of 2013 for a two year deployment, and returns in January 2016 for further measurements. HALO collects high-resolution vertically staring data and takes vertical velocity variance and aerosol backscatter signal strength profiles. The High-Resolution Doppler Lidar (HRDL) installations occurs in the Spring of 2014 short term.
