Climate Smart Agriculture in Asia: Measurements, Implementation Strategy and Challenges
by Kritee Kritee, Senior Scientist, International Climate, Environmental Defense Fund
Biography: Kritee is a part of Environmental Defense Fund's international climate team that is linking farmers to the carbon market in ways that promote mitigation, support development in the rural economy, accelerate poverty alleviation, and strengthen adaptation to the effects of climate change. She is helping lay the groundwork for agricultural carbon offset protocols for small land holdings by directing a multi-partner research team at the five GHG (nitrous oxide and methane) measurements laboratories across three states in Southern India. This research team is examining the effectiveness of innovative farming practices in delivering the three-fold goal of increased crop yields, better farm economics and decreased GHG emissions. She also provides scientific input to EDF's domestic legal teams' efforts to improve government policies related to the energy sector, with a focus on mercury pollution from electric generation units.

Iodine Monoxide observations from CU AMAX-DOAS aboard the NSF NCAR GV research aircraft
The CU Airborne Multi-AXis Differential Optical Absorption Spectroscopy (CU AMAX-DOAS) instrument was deployed for the TORERO and CONTRAST field campaigns. These were in the Tropical Eastern Pacific in January-February 2012, and the Tropical Western Pacific in January-February 2014 respectively. We report the first scattered light limb measurements of IO. I will discuss a number of highlights from our observations: 1) instances of enhanced IO mixing ratios in the transition layer 2) a free troposphere background of IO that shows little variation with altitude 3) a hemispheric gradient in total IO column and 4) the first quantification of IO in the lower stratosphere. These measurements provide the best constraints to date on IO outside the planetary boundary layer. They offer the chance to begin assessing our understanding on iodine chemistry in the transition layer, free troposphere, and lower stratosphere and its impacts of climate, particularly tropospheric ozone.
