Results have shown that the land use impact such as agriculture and urbanization can be detected in the monsoon rainfall climatology especially in terms of changes to the extreme rainfall patterns such as droughts and heavy rain events. One of the notable and enduring contributions of this project has been establishing the role of land surface feedback as a detectable and important component of the monsoon system. These impacts are relatively well understood and documented for local scales but understanding the feedbacks on the regional climate and the detection of landcover feedbacks within climatic datasets has been a challenge. Each of these changes has an impact on surface energy balance, and surface hydrology. There are also natural changes associated with the land surface as a complex feedback of the hydrological cycles and associated water storage, soil moisture and soil temperature as well as vegetation phenology. The effects associated with land surface changes are manifested as a response to population growth and economic changes and noted through physical changes such as urbanization, and agricultural intensification. Landuse landcover change is the other global change underway in an era of greenhouse gas driven climate change. Their policies may differ from this site.

PUBLICATIONS PRODUCED AS A RESULT OF THIS RESEARCH Results of this work will be actively disseminated through participation at professional annual meetings and conferences, and in peer-reviewed journals, and popular media. These activities will be transformed to a media content website, as well as in 4H handbooks, state fair activities, and for visualization and student activities digital libraries. Working with middle school teachers, project findings will be used to develop middle school classroom monsoon activities. The research will directly contribute towards the training of graduate students and postdoctoral researchers. As a broader impact, using the research findings, educational material will be developed for general public, undergraduates, and advanced graduate students. This will enable knowledge that is transformative to weather and climate models and helps develop a more complete understanding of the climate change processes over the Indian monsoon region. It will also improve the understanding of the mechanisms of monsoonal convective processes and its predictability, including the impacts of land use land cover change and land surface variability. Using multidecadal in situ and remote sensed observations, and results from land data assimilation system and coupled land atmosphere models, this project will yield an improved definition, attribution and prediction of the Indian Monsoon rainfall changes. The project will address the following outstanding questions: (i) What is the impact of land surface processes on convection and heavy rainfall over the Indian monsoon region? (ii) Is there a causal control of local land surface feedback on the Indian monsoon heavy rainfall climatology?, and, What aspects of this land use feedback can be detected from current observations, models, and reanalysis products? These questions seek to investigate if the impact of land surface processes can be statistically detected from multidecadal analysis and observations and what are the mechanisms by which land surface affects regional convection and heavy rains over the Indian monsoon region. The study seeks to test the hypothesis that the land surface feedback is an important modulator of the heavy rains and convection climatology over the Indian monsoon region and that the land use change has significantly contributed to the changes in the heavy rainfall climatology over the Indian monsoon region in recent decades.
