This book captures one person's love of nature and our natural world. It is a 57 year journey capturing memories of our natural world. This book is also a plea for all to help save our planet. It addresses the thought of if we love it then we will protect it. A few chapters are: Interconnected, Nature and God, Saving Earth ,Life and Death, Mountains, Water. etc.
Recent development of accurate instruments for measuring greenhouse gas concentrations and the ability to mount them in ground-based vehicles has provided an opportunity to make temporally and spatially resolved measurements in the vicinity of suspected source locations, and for subsequently estimating the source location and strength. The basic approach of using downwind atmospheric measurements in an inversion methodology to predict the source strength and location is an ill-posed problem and results in large uncertainty. In this report, we present a new measurement methodology for reducing the uncertainty in predicting source strength from downwind measurements associated with inverse mod...
The Indianapolis Flux Experiment (INFLUX) was designed to develop top-down methods for measurement and modeling of urban fluxes of greenhouse gases (GHG) to the atmosphere with spatial and temporal scale of one km. and one hour respectively. A small bias in the observation data relative to the background can introduce significantly large bias in the computed fluxes if it is relatively high to the emission enhancement. Hence, it is important to maintain accuracy of in situ GHG data for unbiased estimation of urban fluxes. Accuracy of GHG observation data can be influenced by quality control (QC) process used for error detection, instrument calibration and error correction. Currently different...
The Indianapolis Flux Experiment (INFLUX) aims to use a top-down inversion methodology to quantify sources of Greenhouse Gas (GHG) emissions over an urban domain with high spatial and temporal resolution. Analyzing the contribution of different source types or sectors is a fundamental step in order to achieve an accuracy level desired for such applications. To this end, the Weather Research and Forecasting model (WRF-ARW) was used along with a modified version of the GHG chemistry module for simulating the carbon dioxide (CO2) mole fraction transport during September and October 2013. Sectoral anthropogenic CO2 emissions were obtained from Hestia 2013 and from Vulcan 2002. Biogenic CO2 emiss...
