The concurrent effects of increasing atmospheric CO 2 concentration, climate variability, and cropland establishment abandonment on terrestrial carbon storage between 1920 1992 were assessed using a standard simulation protocol with four process‐based biosphere models. Over the long‐term(1920–1992), simulations yielded time history uptake that is consistent (within uncertainty) long‐term analysis based ice core data. Up to 1958, three analyses indicated net release from ecosystems atmosphere...
Abstract In terrestrial high‐latitude regions, observations indicate recent changes in snow cover, permafrost, and soil freeze–thaw transitions due to climate change. These modifications may result temporal shifts the growing season associated rates of productivity. Changes productivity will influence ability these ecosystems sequester atmospheric CO 2 . We use ecosystem model (TEM), which simulates thermal regime, addition carbon (C), nitrogen water dynamics, explore issues over years...

A globally integrated carbon observation and analysis system is needed to improve the fundamental understanding of global cycle, our ability project future changes, verify effectiveness policies aiming reduce greenhouse gas emissions increase sequestration. Building an requires transformational advances from existing sparse, exploratory framework towards a dense, robust, sustained in all components: anthropogenic emissions, atmosphere, ocean, terrestrial biosphere.

Environmental impacts and net-energy of hydrogen production via solar-electrolysis are highly sensitive to operating constraints context specific variances.
Green ammonia has received increasing interest for its potential as an energy carrier in the international trade of renewable power. This paper considers factors that contribute to producing cost-competitive green from exporter’s perspective. These include resource quality across sites, operating modes off-grid plants, and seasonal complementarity with buyers. The study applies a mixed-integer programming model uses Australia case because excellent solar wind resources, synergy between...
Abstract. The CO2 source and sink distribution across Europe can be estimated in principle through inverse methods by combining observations atmospheric transport models. Uncertainties of such estimates are mainly due to insufficient spatiotemporal coverage biases the In order assess related use different models concentration field over has been simulated with five Eulerian as part EU-funded AEROCARB project, which main goal estimate carbon balance Europe. contrast previous comparisons, here...
As the global transition toward sustainable energy gains momentum, integrating electric vehicles (EVs), storage, and renewable sources has become a pivotal strategy. This paper analyses interplay between EVs, integration with Indonesia’s grid as test case. A comprehensive system modeling approach using PLEXOS is presented, historical data on electricity generation, hourly demand, energy, multiple scenarios of charging patterns EV adoption. Through series scenarios, we evaluate impact...
There is substantial evidence that soil thermal dynamics are changing in terrestrial ecosystems of the Northern Hemisphere and these have implications for exchange carbon between atmosphere. To date, large-scale biogeochemical models been slow to incorporate effects on processes affect with In this study we incorporated a module (STM), appropriate both permafrost non-permafrost soils, into ecosystem model, version 5.0 Terrestrial Ecosystem Model (TEM). We then compared observed regional...

This paper summarizes some features of the interannual variability tropical CO 2 sources during 1980–95. Sources are derived from inversion atmospheric concentration and isotopic data using three different techniques two transport models. We show that source is significantly correlated with SOI. Composite for ENSO events an initial negative anomaly followed by a positive anomaly. tentatively attribute to ocean terrestrial response.

Continuous measurements of atmospheric CO2 over the continents are potentially powerful tools for understanding regional carbon budgets, but our limited processes driving high-frequency variability in these makes interpretation difficult. In this paper we examine synoptic (⊼days) surface concentrations four continental records from Europe and North America. Three source functions corresponding to ocean, land biosphere anthropogenic sources sinks have been implemented a transport model....
Atmospheric reanalyses are a popular source of wind speed data for energy modelling but known to exhibit biases. Such biases can have significant impact on the validity techno-economic assessments that include simulated power.
