Balancing Regional Greenhouse Gas Budgets: Accounting for Natural and Anthropogenic Flows of CO2 and other Trace Gases provides a synthesis of greenhouse gas budgeting activities across the world. Organized in four sections, including background, methods, case studies and opportunities, it is an interdisciplinary book covering both science and policy. All environments are covered, from terrestrial to ocean, along with atmospheric processes using models, inventories and observations to give a complete overview of greenhouse gas accounting. Perspectives presented give readers the tools necessary to understand budget activities, think critically, and use the framework to carry out initiatives. Written by a combination of experts across career stages, presenting an integrated perspective for graduate students and professionals alike Includes sections authored by those involved in both early and later IPCC assessments Provides an interdisciplinary resource that spans many topics and methodologies in oceanic, land and atmospheric processes

The book addresses in a comprehensive way the full greenhouse gases budget of the Italian landscape, focusing on land use and terrestrial ecosystems. In recent years there has been a growing interest in the role of terrestrial ecosystems with regard to the carbon cycle and only recently a regional approach has been considered for its specificity in terms of new methodologies for observations and models and its relevance for national policies on mitigation and adaptation to climate changes. In terms of methods this book describes the role of flux networks and data-driven models, airborne regional measurements of fluxes and specific sectoral approaches related to important components of the human and natural landscapes. There is also a growing need on the part of institutions, agencies and policy stakeholders for new data and analyses enabling them to improve their national inventories of greenhouse gases and their compliance with the UNFCCC process. In this respect the data presented is a basis for a full carbon accounting and available to relevant stakeholders for improvements and/or verification of national inventories. The wealth of research information is the result of a national project, CARBOITALY, which involved 15 Italian institutions and several researchers to provide new data and analyses in the framework of climate policies.

This book assesses the current greenhouse gas (GHG) monitoring capabilities of Europe, identifies and quantifies the uncertainties involved, and outlines the direction to a continental scale GHG monitoring network. The book uniquely addresses both the methodology of carbon cycle science and the science itself, providing a synthesis of carbon cycle science. The methods included provide the first comprehensive coverage of a full GHG accounting and monitoring system.

Cropping systems can be net sources or net sinks of greenhouse gases (GHGs) depending on climate and management. Agriculture can be a sink for carbon dioxide (CO2) if climate and management conditions are conducive for the build-up of soil organic matter. At the same time, agricultural soils are the main anthropogenic source of nitrous oxide (N2O), which is both a GHG and an ozone depleting substance. The work presented in this dissertation investigates the dynamics of CO2 and N2O fluxes over terrestrial systems in the Pacific Northwest (PNW) using measurements and modeling. The first study used the eddy covariance micrometeorological method to monitor fluxes of CO2 for two years at two agricultural sites representing the low- and high-end of the regional precipitation gradient. Combining the measured net ecosystem exchange of CO2 with information on carbon (C) export during harvest, we found that both sites were net carbon sinks. The high-rainfall site had a two-year C balance of 202 +/- 60 g C m-2, and the low-rainfall site had a C balance of 444 +/- 34 g C m-2. The second study used the flux gradient micrometeorological technique and automated static chambers to measure N 2O emissions over one year at two agricultural sites, one under no-tillage management (CAF-NT) and one that had conventional tillage (CAF-CT). The chamber results indicated total annual emissions of 2.7 +/- 1.6 kg N2O-N ha-1 and 4.4 +/- 3.2 kg N2O-N a-1 from CAF-NT and CAF-CT, respectively, while the flux gradient results indicated that CAF-NT and CAF-CT had total annual emissions of 2.1 +/- 0.4 and 1.7 +/- 0.3 kg N2O-N a-1, respectively. The third study investigates coupling the GHG processes in the Community Land Model (CLM) with a PNW regional air quality model. Results from two exploratory model runs are presented, which indicate that using CLM can strengthen monitoring and improve emission inventories in the PNW. The policy chapter is a review of California's plan to reduce elevated drinking-water nitrate levels, which are due to agricultural fertilizer use. This is a case where open-access to publications and data sets would expedite the formulation of good policy.
